OK, so my question is...what is the max fp you should have? My buddy just did the BD setup with the oil pressure switch. He likes it cuz the pusher isn't pushin till it sees oil pressure. He also thinks that if the stock one fails, the pusher will keep pushing right throught the stock lp. What do you guys think?
My next upgrade is a new lp/big line kit. Does the FASS pump come with big lines and fittings or do I need the Vulcan big line kit with thte FASS pump? Thanks...

 

whats the max? well that has been debated more then ford vs chevy, I keep my 30lb gauge stuck on the pin, some guys say that is too much, well I have 70k on it that way so it must work.

I have unplugged my pusher and the stocker will pull through it, but I would not reccemond running that way for long. if you get the carter rv pump at napa it comes with a check valve set up so you can run a bypass the makes it no more resistance then stock to pull fuel. can't say on the fass.
