What Walbro pumps does this fit?

This harness is a universal fit for most Walbro GSS series fuel pumps. The connector end matches the GSS pump electrical connection and the open pigtails splice into your vehicle wiring.

What else do I need for installation?

You will need butt connectors, Walbro part number 187-113, to connect the open pigtail ends to your vehicle's fuel pump wiring. These are sold separately.

What gauge wire is this harness?

The harness uses 14 AWG wire across its 12-inch length. This gauge is appropriate for the current demands of GSS series high-performance fuel pumps and helps maintain consistent voltage delivery.

Product Details

Swapping in a Walbro GSS fuel pump often means the factory wiring connector does not match up. This universal wire harness from TI Automotive (Walbro) gives you a clean connection with the correct GSS pump connector already attached to one end and open pigtails on the other for splicing into your vehicle's existing wiring.

The harness runs 12 inches in length with 14 AWG wire, which is appropriately sized for the current demands of high-performance fuel pumps. The thicker gauge helps maintain consistent voltage at the pump, which matters for keeping fuel delivery steady under load. You will need butt connectors (part number 187-113) to tie the open pigtails into your vehicle harness. This same wire harness is used in the TI Automotive GCA311 pump kit, so it is the factory-recommended connector for the GSS pump lineup.

For anyone building a custom fuel system or replacing a damaged harness during a pump swap, this is a small part that avoids improvised wiring connections that can cause voltage drop and inconsistent pump performance.
