I could tell these O-rings were swollen when I rebuilt this DFR, but I didn't realize they would blow off the valves while I was test-driving. And I CERTAINLY didn't expect the engine to just STALL. But after a tow-truck ride, and some foul language, I came up with this.
I drilled a 1/16" pilot hole ~1//4" into each valve's center. Then I widened it with the drill tip of this standard Ford trim screw. I found out the hard way that even this short screw is too long, so I cut a pair down to ~2 threads, and installed them to keep the O-rings on the valves.
To permanently eliminate the reservoir, use
these Dorman fuel tubes.
A reservoir marked "DO NOT REMOVE CUP" does not contain a filter. For a replacement O-ring for the cup, buy a NAPA 3268, Fram CG3862, or equivalent filter.
