.. should be good for 700 or more.yeah then one shits under full power and bye bye engine
Id rather have just one pump quit and loose fuel altogether than have one pump out of the two quit and let the engine still be running in possible serious lean condition

I borrowed Dave's Weldon and it cleared that right up. The Orange car had a Weldon on it. With both pumps running base pressure goes up maybe 2-3 lbs at idle. Either one should be fine. Also run two filters, one before the pump and one after.

I run an Aeromotive Pro pre-filter and a Aeromitive standard post filter. Braided line the whole way, no hardlines.
I have -12AN line from the fuel cell to the pump, then -10AN from the pump up to the engine bay, I have a Y-block in the engine bay where it splits to two -8AN lines and each -8AN line goes to an end of the fuel rail. I got the Weldon 2040 regulator.

Aeroquip Push-lock is a cheaper alternative from cell/tank to the engine bay. It is a very durable hose.

I have a Weldon 2035. Pressure started dropping at about 1250 rwhp at the track. I added my old Accel DFI pump that I used on the Cobra. It flows about the same as the 2035. They aren't too bad if mounted properly. Here is the video of the Weldon that was bolted right to the car with no isolators.http://www.youtube.com/watch?v=8Qc07FKciTc
If I can make room I am going belt drive this winter.. I don't like the idea of two pumps.
Sounds like tornado sirens. :fork:

maybe I'll give it a try, thanks

How loud are the Weldon pumps? is the pump like you have good for continuous use or no?I picked up a Magnafuel 4301
Any of you heard good or bad about these pumps?
FWIW
I have been using that exact pump for the last 2 years. It is a great pump, I had one issue with it overheating, but after sending it in and them fixing for free its been flawless. It was 95 when it overheated, i havent heard of such problems with other users though. There was older style wear plates in there that expanded and locked it up when overly hot.
I have a 74micron pre filter and a 40micron post filter. I have part #'s if you want and it will save you money buying direct rather than through a vendor.
-8feed and -6 return (Stainless all the way)
Line runs in one rail across the front through the other, out the back,and into the magnafuel fuel pressure regulator.
Depending on your power goals you may want to increase line sizes.
