Fuel Leak ... need mobile diesel mechanic

just started today,
took ten minutes to start, first around noon when we wanted to leave the grocery, then later in the evening going back to homebase location

I did have a mechanic, i called him, he has stopped doing mobile and is shop only, wants me to drive there, bring it in, 35 miles
i don't like that idea
since it looses prime while sitting, it is probably something to do with the high pressure side to the injectors, the HP pump or the lines or the injector distribution manifold/block? what ever they call that thing, yeah it won't be cheap, i rather not risk a fire
i have road service, but they like to tow to the nearest shop, and my guy is NOT the nearest one, rather spend the money on the mobile mech than on the tow truck, paying the extra miles,
if i have to tow, i might go to cumins in Ventura
but prefer local service

going to call in the morning and cancel that appt, and ask for a mobile recommendation
i'm sure he knows other mechs, that do it, it was his living for years
but i sure would like some fall back names and numbers
service area San Fernando Valley, LA county, Calif
Class A

    Take a look at where it is leaking from. Might be nothing more than filter is loose. Maybe fuel line or cracked injector line. Put some cardboard down for now, so you don't have to lay in mess in the morning.

    After you get done "looking" put those clothes in a separate plastic bag and wash separate or throw away. Those starters are big $$$ to just grind away trying to start an un-primed motor.

    its not the main fuel filter, i checked that
    its coming off something on the engine
    will lift the bed, and take look after breakfast

    i did NOT grind on it solid until it started, just tried it 7 or 8 time in that 10-15 minutes

    Does that 5.9 have an engine mounted lift pump like the ISC? If so they can develop leaks due to ULSD. On the ISC there are three bolts on the top of the lift pump that you can tighten and stop the leak.

    You beat me to it JetAonly...I too was thinking the possibility of the Lift Pump, if in fact his rig/engine has one. Not sure if they used them on the older models as far back as '95. If it is however, even if tightening the bolts gets it to stop, that will be a very short term fix. But, maybe enough to get it to the shop.

    MrWizard...Also, check the fittings on the fuel line(s), especially at the lift pump manifold (on top of the pump). You may simply have a loose fitting. Not common, but it could happen.

    A couple of years ago, my lift pump started leaking just out of nowhere one morning while preparing to leave on a trip. It was enough of a leak whereas driving it wouldn't be prudent. This was a Friday evening after everything had already closed (naturally), so unhooked the toad and back into the yard it went with that weekends trip now cancelled. Called the Local Cummins Northeast on Monday and they had one on the shelf. About $300.00. Did the replacement myself. I was just glad that it happened while still home, and not somewhere down the road! ($$$$ !!!)

    I finally located the other guy, my first choice Paul's truck service
    Also Santa Clarita
    I just left him a msg
    I will call Jeff bevis, if Paul can't get to me
    Thank you

    I have been under and over the engine
    And comparing what I see to the engine manual
    Looks like I have a Bosch P7100 inline injection pump that is going south
    It's all wet on the exposed end away from the engine
    (Way too much plumbing for me to get involved)

    The little thing the Manual calls the lift pump is down load on the other end of the engine and is dry
    This is the B series 5.9 with mechanical injectors 230hp
