Quadrajet Problem Solving > Dialing in your rebuilt Quadrajet carburetor
7045214, w/ complete kit from Cliff installed, recipe #2, WOT problem.
77cruiser:
That may not be enough pump, you might have to get something a bit bigger.
Maybe in the 100 gph range.
spluhar:
45gph is 1 mpg @ 45 mph. That's not enough? 5/16" id (.3125) (3/8" fuel line) is waaaaay bigger than .135 seat size.
77cruiser:
The pumps are rated at free flow, so under 5-6 lbs. pressure they don't put out that much flow.
429bbf:
spluhar did you ever get your problem figured out? what kind of rig is this in ? just curious.
spluhar:
No, haven't dealt w/ it. I have a hard time spending another $130 on a $20 ebay carb. A new fuel pump may not even eliminate the problem.
It's a 76 Ford Elite. 1971 429 w/ ported stock valve heads and a mild cam. 3:25 rear, cast iron manifolds, c6 trans.
What did Ford do w/ the 429cj? What did Buick do w/ the GS455? Mine isn't that far off of these notable qjet cars.
