[TR] TR4 Fuel Line fittings at Fuel Pump

[Brian Jones]

Listerati,

I searched the archives and thought I'd found my answer, however the 5/16"
NPT and 1/4" NPT fittings I just bought do not fit the inlet/outlet on my
TR4's mechanical pump. Close, but no cigar.

Could anyone please tell me what threaded fittings I need for attaching to
the TRs mechanical pump?

Also, I want to build into my fuel delivery system an auxiliary,
low-pressure facet pump. Would such an 'in-line' pump be able to pump
through the mechanical pump, or do I need to bypass it, should the
mechanical pump fail (again)? Yes, that was my Labour Day: the ignominy of a
tow.

Interestingly, I'd have expected a stuttering stop with a fuel delivery
failure. I was in third, gunning it up a hill and it stopped pretty quickly
(2 seconds from full power to stopped engine). Almost like shutting down
with the key. I guess at 3-4,000 rpm, it's consuming fuel at a fair clip.

I'd have normally assumed an electrical failure, but this felt different. I
pulled the line to the front carb and span the engine. N'er a drip came
forth. Nada. I have a half tank of fuel.

I am rebuilding a spare fuel pump I have from ebay. It seems OK (i.e it
sucks air when I work the lever) but I'm rebuilding it with a TRF kit. I'm
swapping pumps because this one is an original with the primer lever; my car
came with a replacement pump with no lever. I note that new replacements can
now be found with the primer lever.
