If you find good flow at the pump outlet, try blowing out the fuel line from
pump to carbs with compressed air. Though it seems unlikely that the line has
something solid in it, blowing it to test is quick and easy. Also check the
flex line from hard fuel pipe to the carb. They can peel internally, impeding
flow, yet not leak externally.Bob

Subject: [Mgs] Fuel starvation issues (or at least I think it is)
Date: Sat, 13 Sep 2014 13:40:52 -0700
The other day, driving home, I nearly didn't make it. Car would come to a
sputtering halt every time I had to climb a hill, then would come back to
life
after I sat for a minute or so.
I checked fuel flow and found it lacking. Thinking it was the (aftermarket)
pump, I replaced it today with a new one. New pump is rated at 1-4PSI,
25gallons/hr. But I'm not seeing that. I'm still getting about 3 gallons an
hour (at the carbs). It took 2 and a half minutes to fill a 16oz cup. I've
verified that the fuel filter isn't clogged (I get the same flow without the
filter installed).
I'm assuming I've got debris somewhere. I'll check the outflow of the pump at
the pump soonish (I've got commitments in the next half hour, or I'd have
already done it). Obviously, if the flow is bad at the pump body, then the
problem is in the tank (or very nearly). But if I get good flow at the pump,
what's the best way to try to restore flow to the hard line. I don't see any
obvious kinks or damage. And if I get poor performance at the pump, just how
miserable is it to get the tank off and fixed?
