Adjusting fuel pressure
Hi,
I'd appreciate some advice on setting up the correct fuel pressure. I have a TR7 with a warmed up 4.6 RV8 with Lucas 14CUX FI and a Tornado chip. I've just overhauled the fuel system: surge tank, Bosch 254 911 pump which gives 4 bar pressure, new filter, new lines and an inline pressure gauge. On the advice of Mark Adams (Tornado) I installed a manually adjustable fuel pressure regulator from a Jag XJS. IN place of the vacuum line it has a screw which adjusts the pressure. I set it to 30psi with the engine off and the pumps running. Is this right? I've also read in various places that these systems need somewhere between 50 and 60-something psi. What is the correct number and how do I set this up? I've scoured the web and can't find the information I want. The car is my daily ride and I take it on weekend track days. Cheers Mike |

Re: Adjusting fuel pressure
As Mark developed the tune he would have done so based on a specific fuel pressure as this affects flow rate etc. No one here knows what Mark did so you will need to check with him.
