[Mgb-v8] Fuel Pump Woes

[edd.rogers at gm.com]

Rick,  you have had 3 fuel pumps fail in rather short order. Maybe the 
problem isn't the pump.  I would check out every thing related.  Is the 
sock on fuel pick up clogged?   Bad ground? clogged fuel line?  collapsing 
draw line from tank?  I find it statistically unlikely that all three 
pumps have failed.  maybe the original then a bad replacement but not all 
3.  food for thought

Rick:

The original SU pump works just fine for a carbureted 3.5L. I've gone
the same route of multiple different after market pumps, but have come
back to the original. Just a thought.


The kicker for me was looking at a UK built V8 powered Group B Rally MG
Metro. They had pulled out the Rover derived V6 and installed a V8 in a
very professional manner. With all of the pumps available, they chose a
good ole' SU one to keep it fed.
