I have a venom fuel rail and wanted to hook up a FP guage and SFMU. People mention the stock fuel rail return fitting is 4-an. So for the Venom fuel rail what size is that fitting on the other side of the rail? I'm assuming that hex nut is what I would remove to hook up the SFMU?

Those with venom fuel rails how did you hook up your FP guage and SFMU?


99 GS

I honestly don't know, but you could take that nut to Lopers down in Tempe and they could match up whatever sixe you needed. Wait. You're in Casa Grande or something. Hmmm... Maybe there's information on the Venom website as to the sizes of the ports on that thing?

As for hooking up the SFMU and gauge, I would think you'd need a line coming out the end of the rail with a T in it. I'm no SFMU expert, though.

Worse, im in Sierra Vista. The nut looks to be about 3/8 with a corse thread. So thats 6an size correct?


From what i gathered, OEM line goes to the rail, but you replae the OEM filter in the rear, then you run a line from the rail exit to a "T" where the guage will go, then from there to the SFMU, then from SFMU you run a line all the way back to the return?

Am i tracking?

^^^^^^^^^^^^^^^^ is correct, but you have to take off your stock FPR from the rear, also.
