View Full Version : Fuel Pump advice.

Since I now have the heads, I'm ready to start buying the remaining misc. crap I need to get the 6 speed + heads and cam in the car.

One of the things I've not decided on yet was a Fuel Pump. The walbro 340 is fairly loud, I've heard that the Aeromotive Stealth Pumps are quieter which I wouldn't mind spending the extra $40 if it was quieter. Anyone know if the Aeromotive pumps are actually quieter?

The Walbro is 255LPH free flow, and the Aeromotive is 340LPH, both exceed what I will need by good margin.

I'm leaning towards the Aeromotive for the the fact that it is said to be quieter, and it also flows a crap ton more. Not that I will be planning on exceeding the Walbro's limits.

I will probably buy the Aeromoitive pump, just wanted to hear if anyone had words on either of them.

isn't that just the walbro 255 pump, the 340 pump I thought the buick guys used for more fuel pressure...?? Never thought the 255 was "that" loud with gas in the tank.

It hums pretty good in his car for sure. My 255 is silent.

I've got the 255 in my car and I don't think its too loud. I can hear it prime before I start the car but with the engine running I don't even notice it..

I have 30# SVO's I'll just be adjusting the FP to match what I need at the injector. If I run them at 48psi the'll be like 38# injectors. If I need more or less fuel I can always change the fuel pressure and reset the injector constant in the tune.

You mean in my car? Yeah, you can hear it in the back seats pretty easy when its running.

Well I do know that the Racetronix is a good pump. Granted its just a Walbro 255 in a racetronix sleeve :)

I hear really good things about the Aeromotive stealth pumps right now. Not a bad choice at all. I know my Racetronix is quiet for sure.

I couldn't find anything about the noise differences between the two, maybe most people just don't care. Its not a decision maker for me, but it is something I would consider.

In the end, I just ordered the walbro 255 tonight. Everyone uses it. Also ordered ARP flywheel bolts. Since I don't have them might as well get something thats less likely to fail. And sometimes it can be a pain to find these in the right grade in a hardware store.

Only a few things left to buy really. Got the fuel system, got the parts. Only a few things left to find. Lower shiftboot for the T56. I can't find one at all, but have seen T-5 boots before. I may try to make that work.

Just my .02 but I have run turbo toyota supra stock pumps in quite a few n2o cars with no issues and they are quiet. They are fairly cheap (bought a couple Denso ones from egay) and also toyotas have a rep for being kinda reliable.
