Fuel pressure to twin 45's
madrallysport - 18/1/08 at 12:26 PM

Guys I have a red top facet fuel pump, running to a filter king regulator, which is then feeding a pair of webber 45 carbs, what is the ideal fuel pressure the regualor should be set to.

Cheers

About 2.5 psi as i remember.
If you have a filter King then a small cheap fuel pressure gauge can be temporeraly fitted to it while you set up.

Cheers snapper, I can get the the lend of a gauge, just wasn't sure what pressure to adjust it too, the car is running on a little when you lift of from full throttle, so I got the carbs balanced during the week, so just want to see if theres too much fuel going into her.

again thanks
