Hey guys I'm with the mass national guard where cleaning up after the recent hurricane. We noticed diesel under the truck opened the hood and the first injector line at the dv on the pump is leaking tried tightining it that did nothing. Any suggestions?

I ended up replaceing the o ring under the delivery valve and that fixed er up

I have one leaking at the rear, probably same problem. How much is involved in replacing the o-ring?

 

its extremely easy remove the fuel line then the retainer plate with a single nut above or below the dv then unscrew the dv that's it
