Fuel Pump Recommendation

[jim hensley]

Anyone have an issue with fuel pressure going to 0 on launch? Had no issues using A2000 Aeromotive pump, and using same setup, bought a megnafuel quickstar300 pump/filter combo cause I liked their filter setup. About 3 tenths off the transbrake, rackpak shows fuel pressure spikes down to zero, right back up, then right back to zero then back up, then fine the rest of the run. Same results when checked pressure on both high side and low side location. Sent in fuel pump and regulator to megnafuel, said everything checked out fine, but did put new o-rings in the pump. Reinstalled and had same problem. Put my Aeromotive pump back on with no issues. megnafuel said they had no idea why this would happen. After further investigation, I was told by another major pump manufacturer to stay away from the pump/filter combo's with the vertical filter's as they can cause this. At least it was a problem in my case..
