Anyone ever replaced their fuel lines from the tank to the engine? Mine have fuel drops on them in the basement and the engine appears to be stalling due to air in the fuel. After 30 seconds the fuel filters go 3/4 empty, engine stalls, I thought it was the transfer pump and i replaced it with the latest updated Cummins pump today, no improvement Then I noticed the fuel drops when I lowered the ceiling down in the basement. The new pump is nice-- it self primes when you change the fuel filters,
