[TR] Fuel pump problems

[Dave]

 "Besides, electric pumps are so MG-ish!!"  Or AustinHealey-ish!  Take your pick.  ;-)

The mechanical fuel pump has a rubber diaphragm that stiffens in time - especially when exposed to alcohol.  I replaced my TR6 pump with an electric which has no such issues but I rebuilt my TR3 pump with a fresh diaphragm for originality reasons.  The electric pump is more convenient when I am putting the cars in storage and draining the tanks.

Jus' sayin'.

List,


I still haven't figured out why something that's worked for over 40 years and, even now, may not be the source of the problem is so eagerly replaced.  And, to boot, it's so much simpler than the replacement: no wires, no electric power requirement,  no connections to come loose, no motor to fail, no special mounting,  and so on and so on.. Besides, electric pumps are so MG-ish!!



The last fuel pump problem I had was on a TR6. Turned out to be a stubborn clog in the steel fuel line between pump and tank. Only replacement cured it.



Just sayin',



Ed Woods.

My Triumph TR4-A starts fine when I pump the fuel pump a few times and seems to run fine for awhile. After about 2-3 miles it starts chugging and tries to kill. I stop open the hood and pump the fuel pump about 20 times and get in and drive for about 1/2 to 1 mile and it chugs again. It takes awhile to get back home this way. I'm thinking of installing an electric fuel pump. Wondering which brand to buy? Some say they pull and push so it doesn't matter where you mount them. I've read where you should mount them close to the tank. It looks like some mount in place of the existing pump as a replacement and other are in combination with the manual pump. Help!!
+++++

Why wouldn’t you just rebuild the pump? Rebuild kits are readily available and the process is pretty simple.
