I am assuming
1 is the main feed
2 is the return line
3 x over
4 x over
MY question is if i get a fuel cell and use the factory sending unit/pump can i hook number 2 into a vent fitting and do away with the x over? Correct me if I'm wrong but I want everyones knowledge.
2,3,and 4 are emissions lines. The dodge doesn't have a return line. You can get rid of 3 and 4 and just run one fitting off ur your fuel cell into #2.
