Wide band came right after I recalibrated the controller, after I recalibrated the controller I noticed the the gauge was read low fuel pressure again but AFR was fine. So jumped on google and found that the heat in the engine bay can cause the liquid filled gauges to read low and to get a correct measurement all you have to do is 'burp' the gauge and release the pressure in the gylcerine by removing the bung in the top. So I did and got my 8 PSI of fuel pressure back No issue with fuel system thank god.

Cleaned the reg found still had the problem ended up finding the issue lay with this http://aeromotiveinc.com/fuel-pressure-gauges-liquid-filled-vs-dry-problem-solution/

Is cleaning the FPR1200 as simple as remove inlet and out lets and using compressed air? Or strip in right down? p.s Sorry not that way inclined

Live in NZ and its 95 cant get any better where I live. Power feed to pump is good and earth is connected to the surge tank/sway bar mount bolt. But can go around tomorrow and check quality of supply and earth with DMM. If its debris how would I go about fixing this? More importantly how would I pinpoint the issue. I replaced fuel filter 3000km ago. Also If it helps when the car lost fuel pressure I was able to use the adjustment on the reg to bring it back up. Then after idling abit I had to reduce it when lost pressure returned as it was to high.

Cool thanks for replies fitted the setup last weekend and was wondering about the intank pump. I didnt have an issue getting the fuel pressure down. Went right down to FPR lowest, then sent a 58PSI. However the fuel pressure seems to randomly drop at times, was sitting in maccas drive through and wideband went to 15.5 pulled over and pressure was at ~40 PSI. No leaks was wondering if I had a bad 044 straight out the box, (was purchased through plazmaman not ebay special)

I have a standard intank fuel pump, plazmaman surge tank with single 044 feeding a plazmaman fuel rail with an FPR1200. I see people talking about a venturi and a check valve in the intank pump assembly and modifying it. What does this achieve and do these need to be modified? Also on start up the car takes a while to start I assume this is because the 044 has no check vavle so fuel drains out of rail? What is the part I need to buy to fix this, do speedflow do something? Any help is appreciated.

Recommend going to see Jonathan at Harman Brothers Racing. What car clubs are there in South Island and what are the normal events, I drive a tuned BF MKII F6 and would be keen at looking clubs if there are any.
