Gents,
After many headaches, frustrations, and calming myself before throwing wrenches, I’m struggling to find a good fuel pump.
Here is what I have found….
The glass pumps are back ordered as the company was bought out by another and they are not making any currently (from chevofthe40s)
I have bench tested 5 fuel pumps and they worked in my hand. (10-15psi vacuum on fuel “in” and 2-4 on fuel out to the carb)
Once I connect up to my engine, I get <6 psi suction and most were 0-1 for output. What I have realized is that the position of the pump lever that rides on the cam has a different travel on each pump even though it’s the same part number (Chinese crap). I have even found pumps that have the lever pointing down instead of up.
Questions:
what pump are you using on your 216, 235 or 261? (Part # and FLAPS?)
What is the orientation of your pump lever?
Thanks,
Chris
