A fuel pump wiring harness purchase line may name a full / OE-style harness, a connector/pigtail splice kit, or a relay/fuse/hotwire path sister — and this catalog does not print a harness-named SKU. The same ticket words can still point at different electrical cartons, so the first job is to name the object before anyone quotes a pump box. Soft-link the wiring, connector, relay, and low-voltage sisters when those pages already own the depth; open KS-360501 only after a pump-side 1987-1995 C/K match, never as a harness cure-all.
Match the purchase line to the physical electrical object
The line may name a full / OE-style harness, a pigtail/connector, or a relay/fuse/hotwire path — not one universal harness SKU. A counter who hears “harness” and ships the nearest pump motor has skipped that fork.
A full / vehicle harness is the longer body-side or OE-style run that replaces worn harness wiring. An OE pigtail / connector harness is the short splice-in plug that Delphi-style notes often call a wiring harness or pigtail in the same breath.
A relay / fuse / hotwire path is a different carton again: kits sold under the harness noun that rewrite battery feed through a relay and protection. Those three readings share a purchase-line name and still move as different objects.
| Ticket reading | What the words may name | What the counter must match | What not to invent |
|---|---|---|---|
| Full / OE-style harness | Longer vehicle or body-side wiring run | Sheet already prints vehicle harness / OE harness | A harness-only Kangsong carton |
| Pigtail / connector harness | Short splice-in plug or connector kit | Sheet already prints pigtail, connector harness, or module plug | Shipping a pump when only the plug is burned |
| Relay / fuse / hotwire path | Relay kit, breaker, or hotwire feed sold as a harness | Sheet already prints relay kit / hotwire harness | Treating the kit as the pump motor carton |
| Not on this sheet | Harness-named job with no printed carton here | Category browse; refuse a fake harness SKU | KS-360501 as a harness cure-all |
Write the object in the same ink as the year and the platform before any carton moves. Shopping rows and install videos mix these cartons under one search label; the counter still has to name which one the bay needs.
A burned connector or pigtail is not a pump carton
Melting or bubbling at terminals points at the vehicle connector/pigtail object; a new pump alone can repeat-fail if that object stays burned. Delphi’s failed-pump analysis puts the heat on a poor connection in the vehicle body harness and says the electrical connector must be replaced or repeat failures will occur.
That case language is order language. The burned plug is a carton of its own, even when the ticket still says “fuel pump wiring harness.”
A short connector harness on aftermarket shelves is often only inches long. It is not the same object as a vehicle-length OE harness, and it is not the pump motor in the box.
When the bay shows a melted shell and the ticket still names a pump, stop the pump quote long enough to write the connector object. The in-tank fuel pump connector sister owns plug depth; this page only forces the naming fork.
When the ticket means a relay, fuse, or hotwire path instead
Kits sold as “fuel pump wiring harness” can be relay/breaker/hotwire hardware; that is a sister path object, not the pump motor carton. Catalog taxonomy on the open web places relay kits inside the harness noun, so the words alone do not prove a pigtail splice.
A fuel pump relay is the switching half of that path. The fuse amp rating already in the power center stays the rating printed on that fuse; AA1Car’s rule is to replace a blown fuse with the same amp rating and never a higher one.
Voltage drop on a live feed can starve a good pump even when a key-on meter briefly looks fine. MOTOR’s 2003 fuel-pump diagnosis treats about 0.1 V or less on the ground side as an acceptable live-circuit return.
That same article flags a positive-side drop above about 0.1 V as a damaged harness connector or wiring path. Keep those figures on MOTOR’s method; they are not a Kangsong amp or gauge line.
From the field: On PerformanceTrucks, a reply says “big pump and stock wires don’t get along.” — PerformanceTrucks fuel pump wiring thread
Read that as a buying objection when someone wants to reuse stock feed under a higher-draw pump. It is not a wire-by-wire install recipe and not a test result for this catalog.
Open the 12v fuel pump relay sister when the ticket is already the relay cube.
Open electric fuel pump relay for the same cube family under the electric-relay label.
Soft-open what causes low voltage to fuel pump when the bay is chasing loaded loss instead of naming a harness carton.
Soft-link wiring, connector, electrical connection, relay, and low-voltage sisters
Aftermarket wiring, in-tank connector, electrical connection, relay, and low-voltage pages already own those lines — soft-link them instead of retelling. This page stays on the object fork: full harness versus pigtail/connector versus relay/fuse path.
Use aftermarket fuel pump wiring when the job is sheet-match to the vehicle plug. Use fuel pump electrical connection when the ticket is the connection itself rather than a harness-named carton.
The in-tank connector sister covers the pump-side plug. The how-to-wire sister covers hardwire steps; keep that depth off this naming page and open how to wire a 12 volt fuel pump only when the ticket is already a hardwire job.
This catalog prints no harness-named product
WooCommerce search for harness returns empty; inventing a harness-only Kangsong carton is out of scope even when aftermarket PDPs print harness SKUs. Vehicle-specific “Fuel Pump Wiring Harness” cartons exist elsewhere with printed wire and terminal counts; this catalog does not print that class of SKU.
When the ticket needs a harness-named object this sheet does not print, stay on products-root without inventing a part number. The printed sheet that does carry an OE-comparable harness line is a complete C/K assembly window, not a harness bottle.
What the C/K assembly sheet means by OE-comparable harness, no pigtail
KS-360501 prints a complete 1987-1995 C/K assembly with an OE-comparable harness and no pigtail connector — not amp, AWG, colors, or a harness-only SKU. The feature line is “OE-comparable harness (no pigtail connector)” inside a pump-plus-sender-plus-housing carton.
The worked listing prints a DC 12 V supply as its working voltage. The main connector line reads 2Pins, and the flow window reads 43.3-49.5 Gph for that same assembly.
OE examples on that sheet include 25168719 and E3902 for the printed C/K window. Amp draw, wire gauge, polarity colors, and harness USD are not printed on that sheet, so none of those lines are invented here.
Maximum Air Pressure 12-26 is an air label on that assembly only. It is not wire gauge, pin count, or harness length.
Select KS-360501 only after pump-side C/K fit; browse products-root for unprinted harness jobs
Unprinted harness jobs stay on category browse; open KS-360501 only when the ticket is pump-side plus the printed 1987-1995 C/K window — never as a harness cure-all. That printed window is the 1987-1995 C/K electric gasoline pump assembly.
| Printed label | What KS-360501 prints | Harness-job misread to refuse |
|---|---|---|
| Vehicle window | 1987-1995 C/K 1500 / 2500 / 3500 | Any harness line outside that truck window |
| OE crosses | 25168719 / E3902 and listed crosses | Using those crosses as a universal harness key |
| Electrical | DC 12V, 2Pins | Treating pins as a harness-only SKU |
| Flow label | 43.3-49.5 Gph | Treating flow as harness length |
| Air label | Maximum Air Pressure 12-26 | Reading 12-26 as AWG, pin count, or harness length |
| Overview | Fuel pump + sending unit + housing; OE-comparable harness, no pigtail | Ordering it as a harness-only or harness cure-all carton |
If the ticket is that C/K pump-side assembly, open the product above. If the ticket needs a harness-named object this catalog does not print, stay on products-root.
FAQ
What wires are connected to the fuel pump?
Power and ground feed the pump motor; sender pins, when present, ride a neighboring circuit in the same module family. Name those roles from the vehicle diagram or the printed sheet — do not invent color recipes on a listing that left colors blank.
What is a fuel injector wiring harness?
A fuel injector wiring harness is a neighbor object for injector drivers, not the fuel-pump electrical carton. Keep injector-harness tickets on their own line; this page only names pump-side harness, pigtail, or relay-path objects.
What kind of wire for fuel pump?
Wire kind and gauge belong to the kit or vehicle diagram that prints them. KS-360501 does not print AWG, so do not borrow a relay-kit gauge or a shopping band to fill that blank.
How to hardwire a fuel pump?
Hardwire steps are a competing install intent. Soft-open the how to wire a 12 volt fuel pump and relay sisters when the ticket is already a hardwire or relay-path job; this page only names that object.
How much does it usually cost to replace a wiring harness?
Shopping and AI panels float price bands that change by object type. This page refuses invented USD; name the carton first, then price the named object from a live quote.
How much does it cost to replace a fuel injector wiring harness?
That cost question belongs to the injector-harness neighbor, not to a fuel-pump harness ticket. Keep injector pricing off this pump-side naming fork.
Is a fuel pump wiring harness the same as a pigtail?
Sometimes the ticket uses both words for the same short splice-in connector; Delphi-style notes equate wiring harness with pigtail on module jobs. A full / vehicle harness and a relay/hotwire kit are still different cartons under the same search noun.
Can KS-360501 replace any burned fuel-pump harness?
No. KS-360501 is only the printed 1987-1995 C/K complete assembly after a pump-side match. It is not a harness-only SKU and not a harness cure-all; Maximum Air Pressure 12-26 on that sheet remains an air label only.
