I'm looking to replace my stock fuel pump before it fails. I was originally thinking about the Walbro's, but have become wary of them because they are loud. My car is stock and I want to keep it as quiet as possible. Aside from buying another stock pump, which is more than I can afford, can anyone suggest some quiet pumps? I've searched for all permutations of fuel pumps and noise, but haven't found much in the way of suggestions. Thanks .

 

I believe VENOM sells an OEM replacement pump.

 

I have a 190lph and its not loud. I mean I can hear it prime at startup, but its not like "WTF!!!"

 

Skoundrel, how would you compare it to stock? I like hearing them prime at startup. It makes troubleshooting easier. I just don't want to hear it while I'm driving. Thanks for the reply.

 

At startup its only a little louder than stock. Driving, I couldn't tell you since my exhaust is loud as ***** lol

 

Anyone else have any experience with the 190 lph Walbro? It is really tempting, but I don't want to get stuck with a noisy one. Also, would anyone know what the stock unit flows? Thanks.

 

bump for the morning

 

hey a got a 255 walbro i droped in my del sol a week or two ago and yeah it primes noisy for like 4 seconds (comparable to you power window rolling up or down ) and the only other time you hear it is after warm up at a stop light it humps a little but who cares turn on your radio at like 2 volume and now more hum!! its not like your on the street and some guy's on the next block changing his oil and is like "wtf is that a walbro 255 fule pump in a del sol!" it tolerable for sure i try to hear it and cant alot of the time

 

I'm with 4ghatch. I have a 255 in my sol. He's right. At start up, it's like rolling down a window. I can't hear mine while driving at all. Stopped, if you listen for it, you can hear it. But it's not the annoying whine you hear on a GM truck. Man, I hate that sound...

 

I've checked the Helms manual and can't find the answer. Would anyone know what the stock pump for the sol flows in lph? Thanks

 

this has probably already been covered, but I wanted to double check. If I put a 190lph pump into a stock motor, would that damage the stock fp regulator, or would it run rich?

 

good question..

 

mabye alittle rich but only be like 20mpt (mile per tank loss) and the fpr would be fine
