Fuel Pump Recommendation?
New motor is almost ready to drop in. Pretty mild street motor which will not see racing etc - just a solid cruiser.
I'm thinking about putting a stock replacement pump on it - thoughts?

Since you're asking, on rarely driven carbureted cars, I usually go with a rear mounted Mallory 140 electric set up. Does have a regulator/gauge mounted to the engine mechanical pump block off plate. Like this set up, as can run the pump to prime a bit before starting, bump the key and you're fired up. Also a switch, to run the carb dry, when putting away. Something to consider.

Thanks for the thoughts on this guys. Vette5.5 - Since we live in AZ, the car can be driven year around - and I'm hoping there wont' be many weeks where I don't take it out at least once or twice.
I was wondering if I needed to go with an upgraded mechanical pump, but thinking it might be a waste of $$ given the application.
BK - what is the motor like if your car? Similar to what I will be running?
Thanks again guys,
Adam

Stock is fine.
Adam,
A stock pump is fine to over 500 hp. provided it is in good condition. The return line keeps the fuel moving back to the tank under light throttle conditions, i.e. cruising, and helps prevent vapour lock in warm to hot climates. Does it get hot in Arizona?
Hope this helps.

Adam - My engine is a fairly mild 383. I do put quite a few quarter mile runs on it each year and the stock type replacement pump works fine Thats with winding 1st and 2nd gears (automatic) to 5,500rpm and crossing the line at about 5,200. The only fuel starvation problem I had, other than float level on my Quadrajet, was with the paper filter in the carb inlet. I removed that and put a large in line filter between the pump and carb, and no more problem.

I went to NAPA 6 years ago (22K) and got a $36.00 new pump with gasket. GM wanted $45 but I drive by the NAPA place every day going to work.
It has worked with now problems and it had no issues with the piping, in fact it looked just like the original one.

That's the key with the QJet, pulling out that little round paper filter - and/or the sintered bronze filter in some of them. Huge flow restriction...

BK - Sounds good. I will be running an Edlebrock Performer carb on a fairly mild 350 so it sounds like a stock replacement pump is good for my application. I just couldn't see the extra $$ of a performance pump being worth it for this motor.
Mikep3 - thanks for the heads up on Napa. I'll be giving them a call.
