Testing fuel lines
I am getting ready to get the rear tub back from the painter on the 110 project and before I start fitting it to the truck I want to test the fuel pump, fuel lines etc... to make sure all works and there are not leaks etc...
It is a stock 4.0 system basically. Question is do I need to have the motor running to actually test it all properly or can I just put 12 volts to the pump and get pressure up in the system?
WIll the fuel get pumped up to the rail and back the return line to the tank without the motor running or any of the fuel management stuff hooked up?
I am trying to get away from having to mock up the entire system just to make sure the lines are all good etc..
THanks for the help.
