[abie_lah]

if i set presure without hose vacum at 60 psi what is presure if i put a hose vacum at fuel regulator??,, my vacum engine at idle is 0.25 and what presure in 15psi boost??

so im assuming thats .25 bar? ill tell ya what it should do. static 60psi once you hook the boost line up with the engine running it will pull about 5-7psi of vacuume so at idle with the boost line hooked up fuel psi will be around 55-53psi. WOT with 15psi boost you should be at 75psi
