Just Kidding! These guys wont lead you wrong! This is what I am running. 45 psi at idle, 43 at cruise, 37 at WOT. :c: I have a Draw Straw, -8 lines on the suction side and -6 on the pressure side running through the factory filter housing. Yes, I still have heated fuel if needed. Dave |

That should limit presure to 25 or so psi. I have over 60K on the current setup. And don't forget, too much is almost enough!! Dave |

You must not have been running these pressures for very long now. Even 25 is still to high. Your gonna end up blowin the internal overflow or the diaphram on the pump if nothin else happens first. 21psi is the max that even Bosch says the pumps will tolerate on a regular basis, the rebuilder I taked to reccomends 18psi max even for competion trucks that they sponser.

I'll keep running it until it fails. This VP has already lasted longer than the factory unit running "spec'd" pressures. :D Dave |
MikeL was who we were trying to go through. As I understood it he is the only vendor for them. At this point I would say that this belt drive pump system is gonna be the only way to go once it catches on. This thing rocks. Hopefully when the next guy is ready to give it a shot you can help them out. I'm already up and runnin on it myself.
