[TR] Fuel pump problems

[dave]

Exact same thing happened to me.   Big indicator for this is that when you open the gas cap there is a hiss as the vacuum created gets filled by air.

 

Of course, this happened when I was driving my teenage daughter home from school.  That is SO NOT GOOD!!!

Good point.  When I first got the TR6 it would run for a while but then cutout.  This turned out to be the tank vent line that goes to the charcoal canister had been routed poorly and was contacting the exhaust pipe and had melted shut.  Fixed that any everything is fine.


Be sure to consider the entire fuel system.

On my wife's 250, we were having a similar problem.  The 2 or 3 miles was enough to get on the highway and up to speed.

Tried all kinds of things.  Replaced hoses in the engine compartment, the coil -  thinking it was getting hot and cutting out.  Checked carb diaphrams, fuel filter.  

Finally, we found a rubber hose underneath the car at the back.  It connects the metal line from the tank to the metal line that goes to the fuel pump.  It was soft (probably the original hose)  and there was enough movement in the two metal lines to let the hose crimp and block the fuel flow.

Replaced it and it solved the problem.

I mounted my facet pump over the fuel pump block off plate (Chevy plate works) and minimal piping mods.

 

Pump mounting holes are very close to the plate.. i started with studs and later switched to rubber mounts (I had some MG exhaust mounts laying around).  While its not at the tank, it is less than 12 inches of lift.  Big filter in front of the pump finishes it up.
