gary2 Posted November 16, 2009 Report Share Posted November 16, 2009 I am losing power down the straight aways, you can ease off the gas get back into it and it goes fine. Am i looking at a weak fuel pump, bad fuel filter,or maybe a bad pump on the carb,Thanks Link to comment Share on other sites More sharing options...

THATS WHAT MINE WAS IT RAN GOOD FOR A FEW LAPS THEN THE CAR STARTED TO CUT OUT. WE CHANGED DIST. AND IT WAS FIXED. ITS A CHEEP FIX TO CHANGE THE FUEL PUMP FIRS OR I WOULD CHECK UR LINES AND CARB FOR TRASH. Link to comment Share on other sites More sharing options...

F5RACING Posted November 19, 2009 Report Share Posted November 19, 2009 what size is the fuel line? changed out pump filter and had carb rebuilt and still had problem. changed to a larger diameter fuel line and seemed to go away. could have been coincidental.
