New Guy - M1009 Fuel Tank Sending Unit Part Number?

[CompoundCuckVee]

I've just bought an 86 M1009, It had trouble idling, you let off the throttle too quick and it will stall, it was probably a filter, or something simple. But I bought after the Portsmouth, NH Highway Dept. got a hold of it, painted it orange, and started running it on kerosene. So I figured I might as well check out the tank, so I dropped it, cleaned it, and im going to use some lubromoly diesel purge before i re-install the tank. But the sending unit was corroded on the inside of the tank, after sitting for two years with half a tank of off-road diesel... So to avoid future problems, I'm going to replace the sender. does anyone know the part number for napa, autozone, or wherever?

Suggestions are welcome for other mods/repairs. I started with the fuel system, and next is all the fluid changes; tranny, differentials, oil, filters, chassis lube, and whatever I gotta do to get it back into top running condition.

I'm new here, and to diesels in general, but I can take some flak, so have at it. I could stand to learn a few things.

its the same part as the civilian blazer with the 6.2L engine.

nobody has the right unit. They've got one, but I take a look at it, and its got three outlets, the one I pulled off the tank on mine, it has four. filler neck vent, feed line, return line, and filter drain. Any ideas?

the fourth line is capped off under the bed, its not used except for draining the tank.

Manuf. part# 25004140 It's from the 289-20-P. The parts guy at the NAPA I deal at, cross matchs it to a NAPA#. You used to be able to do it at their web site. But they took it off, why who knows? 9 out of 10 times the part#'s cross over out of the military parts manual (CUCV & M880s) Not the NSNs It has to be the Part # OK.

I just noticed in your first post, that they ran the truck on kerosene. Thats not the best thing for the injector pump, as its not as lubricative as regular diesel fuel. Depending on if they ran it on that for a long time, you may be looking at a injector pump rebuilt in the future.

Welocome aboard. Everyone on this site are very knowledgable with a lot problems with our MV's.

Alright Thanks guys. I just found the part number in 289-20P, it does cross over to the napa #, autozone too. Autozone wanted $106 for it, NAPA took $70.

And yeah... they ran it on kerosene for a year or two, and then let it sit for another year with 1/2tank of it. It was pretty pale, so I'm hoping they were at least blending it with diesel. An injector rebuild is on my to-do list though. As soon as I get an intake, I figured im right there anyway, why not just unbolt and at least clean the intake mani. But when I dropped the tank the lines on the sender were rusted from about a half tank up... Looked like rock candy.

Wow, that really sucks! Rust sucks!

I happen to have a spare J code intake. I'd let it go for cheap. Shoot me a PM if your interested.
