how can I find a leak in my fuel system. 93 f350 4x4 non turbo
Hi I need to find out how to find the leak in my fuel system because when it sits for a hour or more I have to spray a little starting fluid to get her to fire and it seams like it is not getting enough fuel when I am driving it, does not have the pickup it should either.
I have replaced the pickup pump, injectors,fuel filter,air filter. 1993 ford F350 7.3 non turbo 4x4 crew cab |
what about when the motor is cold? will it start by itself first thing in the morning?
|
it is even harder to start then. Its even whose yet if it drops below 40 F outside
|
disconnect lines at tank... and at injection pump.... use shop air down regulated down to 5 psi or so..... then get good heavy soapy spray bottle and you will fid leak quick...its time consuming to do but its the most efficent way to nail it with out chasing ur ass all over the truck and guessing and shooting in the dark....may use as much as 10 psi but i wouldnt suggest goin over 10 psi...... let us know what ya find..
