time to service the fuel filter on my work truck.I've got a couple of questions.
1- is the spin on filter under the hood the only fuel filter to change?
2-Is this system under constant pressure and if so how is the best way to relieve it without making a mess? Do I find and pull the fuel pump relay to let the engine bleed off the pressure while running?
I'm not versed on deisel trucks so much as I am the heavy equipment we use.
