It usually varied between 38 and 42. There is a dyno test showing gains in 45 and 50 fuel pumps though, its somewhere on here. FAQ I think.

The HSR should work with your stock pump. If you buy a Holley pump.......Walbro makes it. Holley just repackages it and passes the love on to your wallet.

If you can show me a product that someone on this board hasn't screwed up on install I'd be surprised. I really think the Walbro is a good product. I'm not saying one or two have never went out the door that wasn't working correctly, but I think it is VERY rare that it happens. I put one in my wife's stroked and blown 97z28 and it supplies over 500 hp at as much as 70psi without making any noise in the car. I like it and highly recommend them also.

I NEVER trust an in-line fuel pump. Not even an expensive one. I have had several and they all failed within a year. I have been running my in-tank Walbro for years without a problem and it is MUCH quiter then ANY in-line pump I've had.

The in-lines were so loud I could hear it over my SPL 1 3/4" heads with 3" Hooker cat-back system (no cat).
