99 Mack E7 460 Fuel solenoid leaking fuel


Recommended Posts

Just bought this truck, well maintained very clean truck. The fuel solenoids are leaking around the outside, hard to tell exactly where but NOT from the fuel line. seems to be from the outer cover where the 4 torx screws are. Is there a seal there? or maybe the o'rings leaking? Any ideas where to look? See pic below.

Yes there is 2 square o-ring behind the solenoid. The screws are tamper torx plus if I remember correctly.

I was hoping it was just an O'ring, I'll be pulling it apart tomorrow. There not leaking much so with new rings hopefully we will be ok. Thanks for the input!
