I'm running alky and seem to have fuel pump problems. I use the Edelbrock victor alky pump I go thru 2 or more a season. Fuel presure seems to drop on them. What kind of pumps do some of you run? And what pressure should I set my regulator at at an idel, which for me is about 1200RPM. Is there a way to check what the max pressure is without reving the P*ss out of the motor. Any help would be appreciated.

The KSE is by far the best setup. If your rules say OEM type pump, use a Carter.

If you can run a belt drive pump its the only ay too go.

I'd try the pro/cam 7.5psi pump and throw all that return line and regulator crap away. Less stuff to go wrong and less weight to carry around, and cheaper in the end.

I have to go with the KSE if its allowed in your rules.

I run the Edelbrock's, too. I don't have any trouble except when the pump has a valve break or the filter plugs. I run a Barry Grant diaphragm regulator( the red one that does NOT have the idle jet) and I just set the car idle at 2500 or 3000 rpm and set the max pressure at 10 lbs.

I run the Edelbrocks too.
I run the BG mechanical bypass.
I've had two problems with the pumps : let them dry out after running them and they go bad, which I don't blame on the pump - I learned to keep them wet with alky / gas / WD40 and that cured that.
My second problem happened just this year when a pump with about 35 races on it started losing pressure at high RPM (meaning 7200 for me). Turns out I broke the spring in the pump, engine builder blames my heavy pushrod. But I plan to keep using them.

I dont know about the fuel sitting in mech pumps causing problems but we have run alky for years with a KSE pump and havent had any problems with corrosion. We run a good top lube to prevent corrosion in the fuel and never touch the system during the season. At the end of the season we drain and flush or oil everything up and its good to go next year.

Ive been down that road myself. My first few years I used the Edelbrock #1711's. (Usually 2 a season).
I was given a few pumps from IMCA's Edelbrock contingency program at the end of 99'. Had 3 DNF's the first 3 weeks in 2000 due to what Edelbrock termed as "factory defects". I guess I got what I paid for.
Have been flowin' great every since using Belt driven pumps. Just gotta keep it regulated!
