Starving for fuel at high speeds - The 1947 - Present Chevrolet & GMC Truck Message Board Network

dion · 04-03-2002, 11:48 AM

I can tell I'm not getting enough fuel on the Highway, when I put it to the floor when I'm going 65-70 it hesitates for a second, I'm using a 1406 600, everything looks good, filter is new, lines are good, pump is new, any ideas?

No help on this subject, but I just wondered if you had any luck on your grill situation yet?

I just put a rebuilt in, I think going to a 750 will help.

Deadman finaly responded belive it or not, he told me the Grille was on the way and should be here this week, I'll let you guys know.

dion, try the carb jetting kit for that 1406. I had the same symptoms when I had that carb set to lean. I would try to richen it before you decide to slap a bigger carb on the engine.

How do you know your problem is fuel? Couldn't it be air?
