Well the one clamp I put on the hose barb slipped down due to vibration. The other one held the hose on,but again I had a slight leak.
My new fitting came today in the mail with the new crush washers. MUCH NICER of a BARB.
None of this undersized crap above a single bulb.
On the left is the OEM fitting, the right is the one I ordered that cost $5.
The hose actually had to be pushed onto the fitting instead of held on like on the OEM one. I reused my stock banjo bolt.

Preliminary testing with cycling the Posi-flo lift pump showed no leaks. Running it in the driveway also showed no leaks. We will see how the trip tomorrow goes. I am confident this is it for the fuel head inlet minor leaking at the hose.
