My in tank fuel pump works OK for the first 20 or so minutes,[1977 stock 4cyl. VEGA] ,
but when the engine gets HOT, It pumps very little gas and the engine runs rough and stalls?
I let the motor cool off for 20 minutes it pumps Ok again???
I can tell by looking at the see-thru in line fuel filter, that Im not getting any or little gas to the carb.
Any suggestions are helpful.
