I have used an electric pump on a couple of different cars now..The 1st couple I did have some issues with reliabliltiy. I do run the pump when the car is going down the track, but the primary use is to get moisture out of the motor after a run. Alcohol injected. I also have a blowoff valve set at 12" just in case
I found on a website that to make the pumps live you have to do some mods to it. I took one apart and did what was listed. That was 4 years ago and have not had a problem since then.
If anyone wants the information on how to modify an electric pump please send me you email address and I can forward it to you...It will be 2 Word Doc files (4 pages in total )
Good luck
