[FC] Repairing Fuel Pumps

[Mikeamauro at aol.com]

"...I'll note that when I have experienced this problem, it was with  pumps 
that had sat for months at a time between run cycles, and it was obviously  
related to the drying-out of gasket and diaphragm materials..."
 
I can see where drying out of the diaphragm  material could lead to leakage, 
but non-use has never played into the  issues with my FC: it is driven daily. 
On the other hand, my 64 Spyder is only  driven about once every 30-days, if 
that, and I've never experienced any  weeping between pump sections with that 
vehicle. I surmise the added heat of the  FC design (and resultant contraction 
& expansion cycling) , along with  the higher elevation of the FC fuel tank 
(in relation to the fuel pump) are  major contributing factors. Regarding FC 
fuel tank elevation: I've  noticed, when I've had fuel pump sectional leakage, 
the leakage is more likely  with a full fuel tank. And, the fuel will continue 
to leak (through  gravity) after the engine is shut down.
