Some Fuel Filter Questions and comments about my terrible week.

[98G]

My M998 is currently dead on the side of the road, 40 miles from home. This is the M998 that's been all over the country and never had a hiccup.

I'm thinking the fuel filter is clogged. I don't know of a source of a replacement that I could get faster than late next week. (Any ideas?)

I've got a CAT spin on conversion that I was planning to use on the redtruck. I'm thinking I'll just convert the HMMWV to spin on and be able to drive it home. Any reason not to do this? (This is the whole point of my post - the rest is just rambling.)

For the last three days Janet has been driving it back and forth to work because I stole her gladiator for a trip to CO to pick up a load of useless military surplus. She has been the envy of the hospital. Yesterday the CEO wanted to drive it, so she let him drive it to lunch and it stranded him. (!!!) They towed it using the strap I keep in it, transfer case in H and transmission in N. At walking speed, maybe a mile. They (not janet) also tried to start it using ether. (Ether is absolutely contraindicated. It's quite possible that they took a trivial problem and turned it into a major one. )

My CO trip was an unmitigated disaster. I blew two separate tires on the trailer, ended up buying tires and tools and broke a jack and dropped the trailer. I was out an extra day, and went way over budget for a trip that wasnt worth doing in the first place. I got to the hospital, tired and dirty, about 9pm last night. I tried to limp the HMMWV home, and gave up about a mile into it when it acted starved for fuel and died.

I'm going after it shortly, with a standard toolset and a towbar. But I'd rather drive it than flat tow it behind the gladiator. A spin on conversion looks straightforward and very do-able on the side of the road. Comments?

Hummer H1 uses an aftermarket fuel filter assembly on his expedition off road rig.

Eric only has about 300,000 miles on it. After-all, it’s just a filter.

You need to also check the usual culprits. Fuel lift pump, fuel line directional valves, clogged sock, water in fuel.

Start by opening up the filter housing…bring fresh diesel and a 5 gal bucket, you need to validate you’re assumption and go from there.
worst case, buy a quick inline filter and bypass the OEM canister, this way you have some level of filtration.
Also very well is the inside of the injection pump…algae does crazy stuff to these pumps.
bring carb Cleaner, clean fuel, a pre-natal baby nose sucker to remove dirty fuel from top of pump, remember, you may need a special bit to remove the top 3 screws on the pump, also bring a bottle of injection pump fuel additive, dump direct 100% into the pump, you aiming to check the
fuel cut off armature….and don’t forget to remove the fuel tank check valves If not already done.

Sorry to hear. This will for sure make you a stronger person...

Just out of curiosity before you get into wrenching and to cover the basics, did someone refuel and putting gas in by accident?

Best of luck.

So today a good time was had by all.

I was unable to locate my CAT spin on conversion. That simplified choices somewhat.

I loaded the toolbox, the towbar from hell and 3/4" feet, safety chain, and took janet's Gladiator and dragged the HMMWV to the driveway.

It towed fine, like a persistent tailgater.

The fuel drain on the driver's side failed to put anything out more than a drop or two. I'm going to blow that line to ensure patency before reconnecting it.

The fuel filter looks terrible. The inner plastic tube not so bad. I think I've located the culprit lesion...

Cranking gets fuel squirting from the tank line, which should sufficiently demonstrate that the sock in the tank is ok, as is the lift pump and the line isn't occluded.

The plan at this point is to clean the filter housing, install new filter and inner plastic tube, reassemble and reassess.
