My LP has started acting a little funny. Immediatly after starting it shows 15psi at idle. But after running about a minute it drops down to 13psi at idle. Is it possible there is some trash or something in the tank that is sticking to the pickup screen while running, then falls off when not running?

 

Could be, there's also a screen on the intake of the pump. Mine's doing something similar, but I figured it's the stock pump that's still inline. Haven't ordered my MaxFlow kit yet. try checking your voltage at the fuel pump also. Maybe it's dropping. Not sure where you are getting power for your pump.

 

Power comes from stock connection. Holley is in stock location per Wildcat Diesel. I will check voltage this weekend.
