lol i don't have a clue, i would take off the fuel line and have a look but i would have to de pressurise the line then fuel would still leak everywhere so thought it better just to ask lol
dont know if its the same on an ep82, but on my ep80 i had to use 7mm hose from the solid fuel return line coming from under the car to the fpr (with 7->8mm adapter inbetween).. from there onwards i used 8mm as my fpr has 8mm hose fittings
sorry to hijac the thread but im looking to put a fuel pressure gauge into 1 of the fuel lines do i put it into the hose coming from the fuel filter or the 6 mmhose coming from the rrfpr
