ok im replacing my fuel pump on my 94 lt1., but want a pump with a higher flow for my paxton setup. i bought 30# ford injectors and am having pcmforless reprogram my pcm for the added boost etc. i have been doing some research and found that you need a harness for the fuel pump on the 94 f-body for afermarket pumps. where is the best\cheapest place i can pick up a high flow fuel pump with the harness for my 94 lt1. are there other pumps besides walbro which seems to be the most common aftermarket pump used, that i can use, such as holley, would i need a harness for the others like the walbro, ive never done a fuel pump in an f-body before so i need some suggestions. i seen that cutting a trap door above the fuel tank would probably be the easiest way to replace it. any suggestions would help, thanks alot!

I would talk to Racetronix they seem to be the fuel pump experts. I would also cut the trap door even if you drop the tank out to clean it out cut the hole so you have easier quicker access especially if you mess something up on the install.

 

Can't got wrong with a Walbro 255 lph.

 

Harness is not needed to make the fuel pump work, it shold plug and run. The racetronix harness us used to deliver better valtage to the fuel pump which inhances it's output.

 

not to hijack the thread, but this pump rated at 255lph without the voltage booster harness right? i would assume walbro would rate it based on the voltage provided by the existing wiring.

 

Racetronix + trap door. Its A+
