Thanks jhv48- Had an
oil filled gauge and switched it out a month ago after it was giving me a hard time. I'll also check for trash in the tank.
I just talked to Mallory about their bypass regulator and Holley about their pump.
Mallory said that the bypass regulator I have relies on the return line to regulate. If my fuel pump is internally regulating/bypassing fuel, it could create an issue of the regulator trying to bypass the fuel at the same time the pump is. They said to "shim" the bypass spring on the pump and Holley should know what I'm talking about.
Holley said the pump does have an internal bypass and should be used with a dead-head regulator. They also said it
can't be shimmed not to self-regulate.
I will try a dead-head regulator first and see what happens. If I don't need the return line at all, I guess I just wasted the time involved in making the return set-up, but as long as it works, I'll be happy.
If it doesn't work, I will replace the pump and use the dead-head. If this doesn't work, I'll drop back 10 yards and punt....
