Solenoid leaking -
If it's leaking from the barbs, check hoses for lacerations & poor connectivity.
or.........
Remove barbs, clean the threads and loctite them back in place.(DON'T OVER TIGHTEN THEM DUDE
)
If it's leaking from inside the solenoid manifold, check the lpr pressure. Shouldn't be more than 90 psi
Check the noid retaining screws for their tightness
If the leak is still there strip it, clean it then lubricate the solenoid and gasket.
If you have a problem stripping the solenoid, i can help you out dude, piece of cake.
