bleoh - we are getting full power to the pumps. They are wired directly to the main power distribution block (through a relay). We verified that we have full power to them all the time.

woh - the pumps are not below fuel level - they are mounted to the top of the fuel cell. The fuel pickup comes ...

Let me add a few more details about the setup. We are running a semi-returnless system. By that, I mean that the regulator is next to the pump back at the fuel cell. The fuel is pumped into the regulator, then to the fuel rail. The return to the tank is from the regulator. There is no return coming ...

Yes. There are a couple places that make the hardware to do that. It has been discussed here a few times in the past. You can probably dig up the old posts using the search.

EDIT - David you beat me by a minute!

Thanks. Thought about that, but the fuel cell is well vented. We thought maybe the roll-over valve in the vent was stuck, but it all checks out OK. I think if we had a vacuum problem then the fuel pressure would not recover immediately when we switched pumps.

We are still stumped.

cavitating pumps - need help!

Here is an interesting problem we are having with the fuel pumps. A pump will run for about 10 minutes, then suddenly will get noisy and fuel pressure will drop. If we flip the switch to change pumps, fuel pressure comes back immediately and that pump will run for about 10 minutes. Again we flip the ...

I know someone that had a setup like that a long time ago (on his AirSensors EFI system) and it seemed to work well. He did run the fuel through a small cooler that was mounted in front of the radiator.

Jerry - I have one that is identical to yours (found it at Fry's) and it did not work. The "other" software is for the "other" ECU that we have in the racer. It has nowhere near the flexability of MT, but that is a topic for outside these forums. Interesting that the converter (the one that appears ...

I was having major problems with the tuning software I was using for our "other" system - I tried every USB/Serial connector I could find and none gave me a reliable connection. I even tried the one that they sell, and it didn't work.

I was on ebay a few weeks ago and found some very inexpensive ...
