View Full Version : How to Check a T-Rex?

My question is, how do you know if the booster pump is bad and not something else?

Last week, power to the T-Rex (Vortech's fuel booster pump) was restored and I sure could feel the difference in power! I could also watch the fuel pressure rise from 35-60 psig. But the pump made a good amount of noise...more than I expected.

Well, as of yesterday, the pump is quieter. But I have lost Hp and the fuel pressure is far lower during boosted acceleration. There is smoke from the tailpipes during deceleration. Needless to say, I am taking it easy on the driving for now.

Your help is much appreciated!
