A few weeks back I asked about the internals of my failed TR6
fuel pump. Several of you responded that the valves should be
staked in place and suggested I try that fix. I did, it didn't
work, so I ordered a new one. Then I really started to screw up!
If you've replaced one, you know the metal fuel line from pump
to carb fits tightly in place with VERY little play to remove
the connections on the pump. With the leverage of the line, and
a slightly different angle of the new pump, I managed to cross
thread the pump output fitting. Dooooh!
OK. So I figured the best way to right that wrong was to get
the tubing and pump off the car, and carefully line up with
original threads. Then with some luck the compression fitting
will seat and hold things nicely. So off they came (side note:
go look at how many things you have to take off or loosen to
completely remove that fuel line!) Still kind of wobbly as
as tried to line up the old threads, so I decided to remove the
compression "ball" and get the brass fitting loose in my hands.
It wasn't loose, so I persuaded it, thinking a new ball would
seal better anyway. Then the fitting wouldn't come off until
a bit of emery polishing was done. A little work had the threads
fitting together nicely. Now for reassmbly.
I figured to replace the brass fitting and the compression ball
just for good measures. First challenge seems to be that the
brass fitting isn't to be found, either in local PepBoys and NAPA
or via the folks like Moss and TRF. No big deal, mine doesn't
look that bad. Second challenge is the compression ball. What
I've found to fit the 1/4" tube are shorter. The original angles
up, then runs flat for a short distance, then angles back down
at the other end. The new one just angles up, then back down.
So I tried anyway, and the fitting seems to bottom out, but not
seal. Cranking sends nice squirts of gas out from around the
fitting, and it's still mechanically loose. I'm getting afraid
of tightning any further.
Not completely sure if the problem is just the smaller compression
ball, or if I screwed up with the emery cloth on the tube. I
thought I'd buy another fuel line, but TRF & Moss don't have
it. I can buy the tubing I assume, but then have to deal with
bending.
Any hints on fuel line bending or what to do about the compression
ball?
Thanks in advance,
Joe
