Anyone happen to know what the thread pitch is for the banjo fitting that connections from the driver fuel rail into the high pressure fuel pump?

With the amount of pressure involved in the pump, I can certainly appreciate that. This fitting is feeding the HPFP, so it should be dealing with relatively low pressures (50-60psi).

I do appreciate the advice, I'm looking to switch it to an AN line.

What makes you think it's low pressure, if it's dealing with the high pressure fuel pump?

Thanks for your help. I've seen it done on a single race car that I helped work with. If only we could find the eBay auction it was purchased from so we can order more...

the good deal is keep DI fuel feed line stock and the same fuel delivery pipe and that connect it to new PI fuel rail unless you donna full boost ur engine then you need alot of fuel that u have to change alot of parts to make ur engine happy with it .

what u need it stock 3 bar fuel rail to keep DI system works . fuel pump to in tank fuel regulator 3 bar to two feed lines (one for DI and one for PI) ans there is no returned line .

good luck
