Hi guys just wondering if anyone can tell me why my vg has low fuel pressure coming out the tank, I have replaced fuel pump, fuel filter cleaned the pump cradle lines but still bugger all pressure, I changed the injectors just to be sure but still hasn’t started, will start if I spray start ya bastard down the intake but not for long,
Could it it be the fuel tank breathers there the only things not connected

otherwise start trying to measure fuel pressure and look at the fuel pressure reg

Did you label the fuel and return lines to make sure they went on the correct way. It's easy to swap them by accident.

Checked the vacuum line on the fuel pressure reg? Or even just the reg itself?

Also, how are you measuring fuel pressure and where did you get your new injectors from?

How do you it has low fuel pressure?

If they're unkown history I'd just change f/pump & filters but also check relay & wiring not only has power but correct volts with multimeter when bridge plug under dash.

Regulator can only check vacuum hose is connected & if it leaks fuel..otherwise buy a gauage to be 100% sure.
