Fuel pressure questions making my own standalone. I have a tank made running a inline pump mr gasket 42s. says will run 2-3.5psi at 42 gph. will be running a 125 plate shot from harris speed. Need to know what jet would be the correct fuel jet to make up the difference for the pressure difference of high to low. Thanks alot !

Call hsw. I'm not familiar with low pressure jetting, but that 2-3.5 seems awefully low? What kind of intake? If your using a vic jr etc if your plate has spray bars i don't think it'll flow correctly with that low of psi.

90 mm plate kit for ls3 manifold. And I just know these pumps can run cars so I figured it would be ok for a nitrous kit. I just needed to know the size of jet. So you don't think I should run this pump then ??

After looking up that pump, no I would not run it. its max psi is 4 and I dont even think it can deliver enough fuel for a 150 shot at 42 gph. I would look up something like the holley blue or black pumps(110 gph and 140 gph) and the holley 803 regulator.
this is all low pressure stuff.
