The Walbro GSS family of in-tank fuel pumps is the single-most trusted name in high performance street and strip fuel pumps. Including the GSS340, GSS341, GSS342 and GSS343 (formerly F20000169), these amazing pumps punch far above their weight when comparing quality and performance to price.

All three pumps are nearly identical but differ slightly only in the position of the inlet relative to the inlet. Choose the configuration that works best for your application. In nearly all cases, the GSS343 kit is the best choice for mid-to-late GM applications, including all GM TBI applications that are upgrading to a high pressure aftermarket EFI System.

Kit includes the basic components you will need to install this pump in your tank. Note that modifications will be necessary to fuel tanks that do not have provision for an in-tank mounted fuel pump.
