Engine trouble

[umpkin]

to fit a fuel pressure gauge, its as shuan said, i had one on mine too coz my fuel reg went badly wrong and doubled the pressure, you put a T bit in the pipe between the fuel filter and the regulator, and then connect the gauge to the 3rd exit off the T bit.

i personnally would be worried to use your idea pukka, i always end up covered in petrol unless things are tightly piped up just clumsy i guess

If my regulator is faulty would it be best to fit an aftermarket adjustable regulator behind the fuel rail ahead of the filter ??...i guess Nissan would want arm and a leg for a new fuel rail and regulator and a used might be no better ??

I have a fuel rail and regulator kicking about somewhere no doubt so forget nissan

Its not my idea. Its a 'lo-gauge'. Its the one below

Thanks everyone for the help, especially adz and pukka ..I got a gunson's colortune and timing light and they seem to work ok, didnt think they did a pressure gauge too.

I managed to find a T piece and an old air pressure gauge and measured the fuel pressure as 35 psi (idling) and 42 psi at WOT so the pressure regulator is working some as far as I can tell but i'm not sure what the spec is

Car flooded again today and I had to take the plugs out and blowtorch them...not going to be very convenient carrying a torch with me incase the engine floods . Tryed removing the fuel pump fuse and flooring accelerator but this didn't work

So far I have : -

Checked timing 18 deg BTDC
cleaned AFM with white spirit and paintbrush
changed engine temp sender
adjusted valve clearances
checked earths at coil and swapped rotor, cap & leads

I tried adjusting the idle CO with the screw on the AFM but it doesn't seem to affect the idle and just turns and turns.....do they go clockwise to weaken the mixture ??
