I finally finished up my fuel pump and harnesses this weekend! Basically i got EVERYTHING from Racetronix.

New Walbro 255 pumps. -8 feed and -6 return













Next was the harness. I order the Hotwire kit for my truck, and an universal kit for the second pump which will be triggered by a 4psi hobbs switch. I also ordered a new bulkhead, 2 x internal harness and weather tight connectors for the 2nd pump and hobbs switch

both harnesses lined up, LONG *****



final product


pump connectors




hobbs switch connector, wires to override the second pump to turn it on and a wire to a dummy light to turn on with the second pump turns on.



fuses, battery hook up and alternator feed





I also picked up this monster filter. it is 9inches long!! it is a little overkill but it was cheaper than the 5inch long one...

 

Who is best to deal with at racetronics? I need to order a hot wire and a hobbs set up like that for my 2000 GMC so I can run 2 walbros!
THANKS

 

Great pics and write up. Why wouldn't they put the relays in the engine bay instead of under the truck?

 

I had good luck with just contacting them via email, since i could not find a phone number. They are also a sponsor on Tech so you could PM him over there.

Well the universal harness has the relay under the hood. The Hotwire kit for my truck puts it under the truck...

 

I Think it's best to have the relay as close to the pump as possible.

 

I don't think it matters really. I'd perfer to have it under the hood so it's easier to get to if it ever goes bad.

 

Nice work Corey, Looks really clean .

Questions- Since i already have the hot wire kit, in order to run a secondary pump i will need to get a " secondary" harness ? If so then i guess i will have to run another one on my truck ( hotwire kit is already installed) , damn. I was hoping to just tap in for secondary pump Off of the main pump.

And you bought the " Y " fitting and Otiker clamps from them also?

I need to go shopping on their site.

 

Why not just use a peice of 10GA wire?
Ground it on the frame at the tank, relay under the hood.

 

Looks good man. Are you running a turbo set up?

 

Yeah i liked the quality of the hotwire kit so i just ordered the universal kit for the second pump. I also ordered anothe internal harness and a wether proof connector. The universal harness was only $45 i think.

I got the Y from lightningforceperformance.

I got the clamps from home depot. Goto the plumbing row and look in the PEX section and you will find them.
