No ill affects, no issues in traffic in Vegas heat and no difference at the track, been like this for 14 years. Pump has been in the car for 22 years....Never had to touch it.


Yeah I ran an old system in my Coronet like that for the first 20 years I owned the car. A couple of Holley pumps located by the rear bumper with no regulator and a long line up to the carb. Worked fine for 20 years of street driving and street racing.

I 'm a firm believer in all return lines for gasoline should enter from the bottom of the tank or cell, not spray through the air into the tanks or cells from the top or sides tsk twocents

We've been using the pump return style method for 20+ yrs, since the last 3 pumps we've had it was built in. Never an issue but I'm thinking of using one of these for added street duty reliability, but to be honest it might be overkill shruggy
