In need of help.
I own a 1986 nissan fairlady 300zr (Z31 with the later VG30DE engine)

The fuel pressure reg is finished on it and as I can't find a replacement in the UK, I'm going to have to buy an aftermarket adjustable one.

My problem is that I have no idea what pressure it should be set to?

I assume it would be the same as the N/A z32. If this is so, does anyone know what I should set it to?

Many Thanks
Sanj

 

Sadly, you're going to be best off finding an Aussie with a manual. Not going to be able to get much help here as there aren't too many 300ZR around, let alone in English speaking countries.

 

If it looks like that, then it's the same as a z32 or anything with a vg30de/dett. Any parts store and more then likely a couple dismantling yards should have them.

 

Thanks guys, My regulator has 2 inputs (one from each bank) and 1 output plus a vacume exit. I've bought an uprated one but also need a new fuel pump!!!
