Fuel pressure(just after fuel filter) shows around 1.5psi. And that's not by tapping into it but by plugging the pressure gauge directly into it.(I ran the engine with the petrol left in the carby float bowl). Revving high won't make any difference, but it shouldn't anyway, 'cos the power to the fuel pump is from the battery.
It should show bit more than that I reckon. What do you think?
I'm not sure whether intank pump's weak or whether its' not getting enough voltage.
Tachometric relay's doing the job of FPCU now.
Voltage was ok when I wired it up & tested it.
I'm just going to give direct battery power to the pump and see whether it can produce a better fuel pressure.
That way I can rule out whether the pump's not getting enough power from the tachometric relay.
