53 chevy with 350 and 2 holley 94's, manual fuel pump, standard fuel pressure regulator with a glass filter.
the other night the engine started to stumble and would backfire when i let of the gas. so i started changing parts like plugs, cap, rotor, filters, etc. i decided that because it was backfiring from both the left and right exhaust pipes that it could be running lean. i looked at the glass filter and the fuel was very low. i changed the fuel pump and blew through all the lines. still very low fuel in the filter.
i ran a line from the filter to a 1 gallon can and the filter was full all the time, WTF
what i'm concerned with is that the fuel filter is empty most of the time. it fills about 1/8 full then runs dry, it does this every 8 seconds. its not vapor lock or a crushed line. air blows through the system well and the car runs fine. but i will be running at high speeds for 6 hr to billettproof and sure don't want to run lean. what do you think?
