In simple terms it is an on off solenoid.
My advice is: not to follow my advice.

This is the ebay adjustable fuel pressure regulator I was thinking about.

One thing that I've learnt from this saga so far with the two Nikki carbies & fuel return valve is that how sensitive the RB30 Nikki carby to the fuel pressure. If the fuel pressure is 4-5 psi, the float level rises too much. If the fuel pressure is too low(1psi or less) then the float level is way too low as to starve the carby of fuel and cause it to run lean and hesitate on accelerator pumping.

Hey Dom14, what ended up being the issue in the end? The Fuel return solenoid or pump?

Dom has been a bit quiet, lately. I can't remember what his solution to the problem was, either. Try this thread, http://www.nissanpatrol.com.au/forum...ul-Hints/page3

Hi all, ended up being the fuel pump.
For anyone else with a similar problem a simple test is to pull the fuel line off the top of the fuel filter. Attach a pipe to the top of the fuel filter and run it into a container. Turn the key enough to hear the fuel pump start and measure the amount that ends up in the container after 1 minute.
Mine had pumped a mere 200ml at most in 1 minute. From what I can find online it should be closer to 900ml - 1 litre in 60 seconds.
Based on this it seemed the fuel pump was the likely cause since I had replaced the fuel filter and left the fuel tank Cap off when testing to ensure there wasn't an issue with negative pressure etc.
If you get enough volume into the container I would then be looking at the fuel return solinoid, carby inline fuel mesh filter (banjo bolt) or the carby itself as these bits are all after the fuel filter which is where the above test tests up to.as such.
