A walbro fuel pump line names the GSS in-tank, GSL inline or external, F90000xxx, or FR reciprocating object that the printed Walbro / TI Automotive Aftermarket application sheet or carton already lists. The same ticket can say walbro fuel pump catalog once and still mean that sheet’s printed family, not a Kangsong SKU. The fork below is the GSS carton (and inlet geometry when printed), the GSL inline path, the F90000xxx / industry-tag Walbro high-flow naming fork, the FR reciprocating carton, shopping numbers that stay off this catalog, and the 1987-1995 C/K truck kit as a different machine.
When year, make, and model are already on the ticket, copy the Walbro sheet first so the shopping carousel stays closed until that object is named.
A Walbro fuel pump line starts on the printed application sheet
A Walbro fuel pump line starts on the printed application sheet, and the carton follows that sheet’s year/make/model plus the printed family / number.
The Application sheet / printed part number is the Walbro / TI Automotive Aftermarket carton or application list that already names a GSS, GSL, F90000xxx, FR, or OE-spec object. At the desk that sheet is the only list worth copying before a Walbro carton leaves the shelf.
A search bar that already says walbro fuel pump still has to open that paper. A shopping carousel of GSS, GSL, F-number, or FR cards can sit shut until the sheet says which object belongs on the line.
Write the vehicle family the way the sheet already prints it. The purchase line copies that ink, and this catalog does not invent a Kangsong card to stand in for a missing Walbro SKU.
Many Walbro sheets already name a GSS in-tank pump
Many Walbro sheets already name a GSS in-tank pump, and the printed inlet geometry matters when the sheet lists it.
A GSS in-tank pump is the printed high-flow in-tank family many shopping pages already name. Inlet geometry is the printed difference between those GSS cartons when the sheet shows a centered inlet versus an offset or in-line inlet — beyond marketing flow tags alone.
That pump moves gasoline (or the fuel the sheet names) from the tank toward the injector path when the sheet is an in-tank GSS line. Wikipedia’s fuel-pump page already separates an in-tank electric class from a carbureted mechanical class.
Copy the printed GSS row, including the inlet note when the sheet has one. Two shopping tiles can both say Walbro and still disagree on that inlet.
A Walbro GSL inline pump is a different printed family
A Walbro GSL inline or external pump is a different printed family, not every Walbro carton.
A GSL inline / external pump is the printed universal inline or external family. It feeds a fuel injector / injection path when that sheet is an external or inline line.
How a Car Works draws the line between a cam-driven mechanical pump and an electric pump that sits next to or inside the tank. That lesson names the drive fork. It does not turn every Walbro line into one in-tank canister.
A counter that already holds a GSS carton while the sheet names a GSL number is holding the wrong family. Aftermarket wiring notes for an external power path stay on soft-link only — aftermarket fuel pump wiring; this page does not retell that harness job.
An F90000xxx line is another printed family when the sheet says so
An F90000xxx high-flow or E85 flex line is another printed family when that sheet names the F-number — not a 255-versus-450 ranking guide.
An F90000xxx / industry-tag Walbro high-flow line is the printed flex or high-flow in-tank family when the sheet already shows that F-number. Industry tag language such as “Walbro 450” is naming evidence on that sheet only. It is not a Kangsong ranking section.
From the field: On an SVTPerformance thread, an owner already asks about premature failure of a printed Walbro F-number (f90000267). Replies worry about fake carts and wrong relief class on that shopping line. — source: SVTPerformance, early death of a Walbro
No pressure, flow, or price figure from that thread is copied here. — source: SVTPerformance, early death of a Walbro
Keep the F-number on the sheet when that is what the carton prints. Horsepower ranking against another marketing flow tag belongs elsewhere.
A Walbro FR reciprocating pump is another printed family
A Walbro FR reciprocating pump is another printed family for carbureted or marine windows when that sheet prints FR.
An FR Series reciprocating pump is the printed aluminum reciprocating / diaphragm electric family for carbureted or marine windows on Walbro material when that sheet says FR. It feeds a carburetor float bowl when that is the printed path, and it is not a GSS turbine canister.
Wikipedia’s fuel-pump page already notes that carbureted engines often use a low-pressure mechanical class, while some layouts use gravity feed and no pump when the tank sits above the carburetor. An FR sheet is still a pump order only when that sheet actually prints FR.
The older cam-lever versus motor story lives on mechanical fuel pump vs electric. This page only names the FR carton the sheet already printed. A brand-sheet sister for another maker’s mechanical / electric split stays on carter fuel pump — soft-link only, never an equivalence swap.
Printed Walbro shopping numbers stay on the sheet, not in this catalog
Numbers such as GSS340, GSL392, and F90000267 stay on shopping pages. This catalog does not print them.
A printed shopping number is a GSS340 / GSS341 / GSS342-class, GSL392-class, or F90000267-class number already on seller pages. It stays a shopping-page object. It does not become a Kangsong SKU.
| Printed shopping number | Where it already lives | What this catalog prints |
|---|---|---|
| GSS340 / GSS341 / GSS342-class | Shopping pages as Walbro in-tank GSS rows (inlet geometry when listed) | Nothing under those numbers |
| GSL392-class | Shopping pages as Walbro inline / external rows | Nothing under those numbers |
| F90000267-class | Shopping pages as printed F-number / industry-tag high-flow rows | Nothing under those numbers |
| This catalog | Empty Walbro product search | The 1987-1995 C/K window only |
A buyer who wants GSS340, GSL392, or F90000267 written as a Kangsong SKU is asking this catalog to invent a card. Keep the number on the sheet and leave the empty search empty.
Those shopping-page objects can sit next to the ticket as reference ink. They still do not open a Kangsong Walbro listing.
KS-360501 is the 1987-1995 C/K window, not a Walbro SKU
An in-tank truck complete assembly is a different machine, and KS-360501 prints a 1987-1995 C/K window that is not a Walbro fuel pump.
Wikipedia’s fuel-pump page describes the job as moving fuel out of the tank toward the carburetor or the fuel injector. The same encyclopedia page places many fuel-injected engines on an in-tank electric pump, or on a high-pressure pump mounted on the engine.
In-tank units there are often an assembly with strainer and sender. That In-tank electric assembly is the truck carton, and a Walbro GSS, GSL, F-number, or FR carton is absent from that truck window when the sheets differ.
| Object family | What the line is naming | What this catalog prints |
|---|---|---|
| GSS in-tank | High-flow in-tank canister on that Walbro sheet (inlet geometry when printed) | No Walbro SKU |
| GSL inline / external | Universal inline or external family on that sheet | No Walbro SKU |
| F90000xxx (when printed) | Flex / high-flow in-tank F-number family on that sheet | No Walbro SKU |
| FR reciprocating (when printed) | Carbureted / marine reciprocating family on that sheet | No Walbro SKU |
| 1987-1995 C/K truck | Complete in-tank assembly for that pickup window | KS-360501 only for that window |
Wikipedia’s fuel-injection page notes that port and TBI systems commonly use an electric in-tank supply, and that direct injection adds a separate high-pressure pump on the engine when that architecture is present. A truck complete assembly offered as the Walbro carton is the swapped machine this page is trying to stop.
Fuel pump assembly vs pump naming stays on fuel pump assembly vs fuel pump. Shared words fuel and pump do not merge those two printed windows.
KS-360501 prints a 1987-1995 C/K complete assembly, and that window is not a Walbro fuel pump. The live PDP title for that kit lists the 1987-1995 C/K 1500/2500/3500 pickup window plus OE marks 25168719 and E3902. Printed electrical and flow fields on that same kit read DC 12V, a 2-pin main connector, and 43.3-49.5 Gph.
Maximum Air Pressure 12-26 on that label is an air figure, and it is not Walbro fuel pressure. The product overview still names the pack as an electric gasoline fuel pump with installation kit and a 1-Year Limited Warranty.
None of those words say Walbro. A ticket that actually names 1987-1995 C/K after the Walbro fork can stay on this window. A ticket that still names a GSS, GSL, F-number, or FR object cannot borrow the kit because both objects can say electric.
Which catalog line fits an unprinted Walbro job
Unprinted Walbro jobs stay on the category. The C/K kit opens only when the sheet is that truck window.
This catalog does not print a Walbro SKU. Browse the catalog for unprinted Walbro jobs when the sheet still names a Walbro GSS, GSL, F90000xxx, or FR number.
Open the 1987-1995 C/K electric gasoline pump only after the sheet already lists that pickup window with 25168719 or E3902.
If the sheet already named a Walbro GSS, GSL, F90000xxx, or FR number, keep that number on the sheet and stay on the category. If the sheet is the printed C/K window, the kit is the carton that can move.
FAQ
What does a walbro fuel pump purchase line still have to name?
It has to name the GSS in-tank, GSL inline or external, F90000xxx, or FR reciprocating object that sheet already prints, plus the printed number and inlet geometry when the sheet has them.
Is every Walbro fuel pump an in-tank GSS pump?
No. Many sheets name a GSS carton, but GSL inline/external, F90000xxx, and FR reciprocating families are different printed Walbro lines.
Is KS-360501 a Walbro pump?
No. KS-360501 prints a 1987-1995 C/K complete assembly. That window is a pickup-truck kit, not a Walbro SKU.
Does this catalog print GSS340, GSL392, F90000267, or other Walbro shopping numbers?
No. Those shopping-page objects stay on seller pages. This catalog does not print them as Kangsong SKUs.
Where does the mechanical-versus-electric drive explanation live?
Use the mechanical fuel pump vs electric sister for drive-type contrast. Mechanical vs electric drive is only soft-linked here so this page can stay on the Walbro sheet fork.
Can the C/K electric kit replace a Walbro GSS or GSL pump?
No. The C/K kit is the 1987-1995 truck window. A Walbro GSS or GSL carton stays on its own sheet.
Is a Walbro GSL inline carton the same object as a Walbro GSS in-tank carton?
No. A GSL inline or external carton is a different printed Walbro family. A GSS in-tank canister is a different carton.
Is the C/K Maximum Air Pressure 12-26 label a Walbro fuel pressure?
No. Maximum Air Pressure 12-26 is the air label on the C/K kit. It is not Walbro fuel pressure.
