You're right on the cap being a temporary fix. I either need to get a new fuel rail (probably from merlin) or I can actually pipe solder a permanent cap in place because the fuel rail is made from copper. I'll probably just get a new rail because I don't want to risk a fuel leak turning into an engine fire
After a suitable amount of time with no pressure, & a good cleaning with alcohol or acetone, you could epoxy the cap on with JB weld.

I know it sounds a little "bandaidish" but I fixed a leaky banjo fitting (fuel) with the stuff two years ago in Moab, & it still no leaky to this day...

I've never looked closely at the schrader valve thingy on the fuel rail, I always assumed (apparently incorrectly) that the innards came out with a valve core removal tool...
