I had installed an electric fuel pump in my 77 Midget and
removed the mechanical fuel pump. This pump was install in
the back of the car by the tank. The car currently has a
1500cc engine with a single ZS carb.
I was going to re-route the steel fuel line to run a more
reasonable route in the engine compartment. This is what
I found. Starting from the gas tank, the line is 1/4" steel,
which runs up front to the transmission tunnel where it curves
up a few inches. There the line switches to a rubber (or whatever
fuel lines) are made of. This rubber line goes up along side the
transmission for about 2/3's of the height. At that point
the 1/4" steel line starts again, and run to the old pump. On the
output side of the old pump the steel fuel line is 5/16", and
this runs to the carb. The input to the carb is 5/16".
The entire run from the tank to the old mechanical fuel pump
was 1/4".
I wanted to run a new steel line from the rubber line at
the transmission. I was going to make it from 5/16" tubing
but I would have a mis-match in size for the rubber hose.
I think these are my choices:
1. Complete the run with 1/4" steel tubing and
force the 1/4" rubber line from the steel tube onto the
carb.
2. Replace the fuel filter at the carb with one that
takes a 45 degree flare fitting, and flare the end of the
1/4" tube at the carb.
3. Run a 5/16 all way from the new fuel pump to the carb.
The easiest solution is number one. Is that asking for
trouble? Number 2 is very doable. Number 3 would require
more work. Is a 1/4" run down stream of the pump a bad
thing? Sometimes I think that I think to much about the small things.
