Product Description

Genuine Walbro 255LPH external fuel pump (part # GLS 392). Made in the USA. The GLS392 Walbro fuel pumps support up to around 500hp at the wheels when wired to ensure they receive a healthy 13.5-14.5V supply.

We also offer this pump with optional fittings. You can either choose 5/16″ or 3/8″ push on hose barb fittings or AN-6 (anodised aluminium) or AN-8 (stainless steel) fittings as commonly used on applications with anodised fittings and braided stainless fuel lines.

This is a universal in-line EFI fuel pump which mounts outside of your fuel tank. This can be used by itself with a fuel cell (or suitable fuel tank) or in series with other fuel pumps or most commonly it is used on high performance applications with a fuel surge tank (note that applications with a surge tank also require a low pressure lift pump to fill the surge tank). If you are building a high-performance fuel-injected machine and require an external fuel pump (or several) then these are a great option without spending a fortune. We have even used two or three of these pumps set up in parallel drawing from a single surge tank to support applications making in excess of 1000hp.


These Walbro fuel pumps have become the industry standard for fuel pump upgrades on performance vehicles.


The deterioration of a fuel pump due to age as well as the extra demands on the fuel system due to performance enhancements mean that replacing your factory pump should be one of the first modifications for your performance car.
