hey guys, i just bought a walbro 255 for my 96 ta, now i know the racetronix kit is very good, but i dont really see what the diffrence is really, besides the hose to the fuel pump. I have used several walboro pumps in my mustangs and turbocoupes and never had a problem wit the hose getting ruined. Is the kit worth it, and whats the deal with wiring it to the alt, do you realy think you need to do that

Are you cutting an access panel or not?
If you are not then go ahead and get the racetronix kit. If you are going to cut a hole then you can skip it in my opinion. I put in a 255 without the kit and had some issues with the hose, had to go back in a couple of times and ended up double clamping both ends to keep from bleeding pressure.

With the access panel its a snap to get to the pump.

The wire to the alt is to keep voltage to the pump. Fuel flow is dependent to the voltage of the pump.

Unless your wiring harness for your fuel pump is better than the stock one that came in the b-cars (prolly the same) I wouldnt be doing any performance oriented fuel pumps without add on wiring harness.

I used a walbro 255 without the race tronix kit in both my 97 cars and they are fine and was 3 years ago for one a 2.5 for the other. they are both still going strong

Mine is suppling enough fuel for a 200 shot on a cam only motor. About 500rwhp. stock wiring. If you going above that you might want the ractronics kit otherwise no.

I assume that's with a 255L?

i see the constant debate about these pumps, but its for the ls1 guys, i know are pumps are diffrent, do our pumps have the venturi? why cant you use the factory gm flex hose?

well maybe the camaro wiring is more sufficient. the b-car wiring completely sucks. You can burn it up with a stock motor with no mods.

I have no problems with my walbro pump, it handled my heads/cam car back when I had a 150 shot with no problems too.

Yes the gss307 255L (not the gss340 high presure)

I just had my walbro/ractronix installed two weeks ago. I like how the fuel pressure sits right where they say it will at WOT, and at idle now I show around 38-39 psi. WOT is 43.5 psi. My stock pump was def. hurting at 159k. I was down to around 32 psi at idle and barely 40 psi at wot. Going to be running a plate kit, so I figured it would be a good thing to do. Who knows, every car is different, jakesz28 is having no issues he says, maybe the next guy would go lean.

I am in the middle of installing mine. The pump itself is a high quality kit and a drop in (no mods to the bucket needed).
The function of the wiring harness is to eliminate the voltage drop to the pump. The wires are much larger in diameter than the factory wiring, and go straight to the alternator. Racetronix advertises 12v (stock) vs. 13.5v (their kit). This should eliminate any fuel pressure drop at WOT.

I have installed both and will only do a stock pump or Racetronix unit if I am doing an intank. They just make sense for most applications. I made my 600RWHP pull with a racetronix kit and yes the wiring. The Wiring IS much needed.

I've never actually seen a Racetronix kit but does anyone see a benefit to running an alt wire on a stock wiring setup just for a fuel pump boost? Cheap mod if so. Was thinking about doing that to mine and using a Racetronix kit on the project car where I'll be running two pumps.

ok i know this is a really old thread but i am about to cut an access panel and replace my fuel pump, and I was wondering if it would be ok if I replace the whole fuel pump assembly with the racetronix fuel pump assembly without using their wiring harness kit??

00blackfirebirdform

I read that their pump ideally runs off 13.5v and that the factory wiring harness only delivers 12v

Im not sure that anywhere sells the whole wiring kit anymore...looked for it a few days ago and couldn't find it anywhere but the ws6store, and that was "pump only"-no kit from what I read...

00blackfirebirdform

they sell a wiring harness with their pump and you can buy one from them that wires straight to the alternator but what im wondering is if the racetronix kit will pug into the factory harness? and if it will supply the pump with enough power to even fuction properly

You can run it with or without the Racetronix harness, but I would suggest using it. Consistent fuel pump voltage is nice. It is plug and play into the factory harness.
