Instrument Services rebuilt my OEM sending unit over this past winter. It looks good for sure, but I haven't installed it yet to try it out. It set me back $405. and took around 3-4 months (if I recall correctly). At the time I sent my original sending unit in to be rebuilt, MTS had their new units on backorder, and they'd been on backorder for quite a few months! Now it's spring and I have both sending units, the original and an MTS.

There's a company that rebuilds the sending unit, if you need that, but it isn't cheap or quick. I'll let others speak to the pump. I have nothing to offer on availability of those for your application.

I'm seeing several used MJ fuel filler necks on eBay. It's another option.

Austin did a little explaining, but I didn't really pay that much attention, as it didn't affect my 4.0 application. He spoke of wiring and mounting issues though.

I didn't know where to drop this info, so I'm putting it here. I've had my sending unit ordered since August of last year. On the phone just now, Austin at MTS told me that they have the JPSU-6 units for the 4.0 back in stock. Pricing is a little over $100. (Sending unit only, that price does not include the pump.) The 2.5 units are still being redesigned and aren't quite ready yet.

The picture above is from the original CL ad. It was a driver when I brought it home, but it had issues. It needed brake work, a new exhaust system, there was a sizeable hole in the driver floorboard, and the A/C was inoperable. Those were the major issues. I'm sure there were others, but those were the biggies. I drove it around a bit just to play, and it was a blast to have a manual tranny again! The brakes I tried to tackle myself. I replaced parts and sent it to a garage to do the final adjustments. While it was there, I also had them charge the A/C and replace a missing fan. (I didn't notice that it was missing, and for a while, neither did they.) When I picked it up, the brakes were great. The A/C was cold. That was the good news. The mechanic also asked if I knew my slave cylinder was leaking. Like...a lot. Bad news. That was NOT going to be a minor repair. And that's when I drove the Comanche home and parked it. For years. A few years later, there was a false start. I thought time and money were going to let me start working on it. I picked up a new Optima Yellowtop, a DirtBound battery tray, and a new set of battery cables from @MeanLemons. I also bought all the parts needed to convert my AX15 internal slave to external. I figured that while I had it apart, that was a good time to do an upgrade. And that was as far as I got. The battery and related parts were all installed. The clutch work never got started. In the intervening years, all the truck got from me was to occasionally start it up and let it idle for awhile. And to add insult to injury, a branch fell out of the neighbors tree and tweaked the front left corner from the header panel back to the door. Darn it!

My first love is my postal jeep. But I finally had to park it because it needs too much work...as in top to bottom, and front to rear. Expensive and extensive work. But I still wanted something to tinker with and do minor repairs on. (Note that I said MINOR repairs. That's important to the story.) In the Summer of 2013 I decided to search for a Comanche. I missed out on a couple, but I finally found one on Craigslist in neighboring Indiana. I rented a trailer, and the lady I lived with at the time and I headed out. We picked up the truck, and on the way back home Kathy spotted something in the ditch along the highway. I bailed out and she found a place to turn around and came back for me. When I got back in the truck, I was carrying a handfull of fluff. This one little kitten was all I could come up with. I looked all over. There was no momma to be seen, and no other babies. This little girl came home with us. We both figured that for Kathy to have spotted her like she did, this was one lucky kitty! So we named her Lucky. My cats are my kids. We lost Lucky in June of this year. Since her memory will forever be tied to this truck, I wanted to start my build thread before the year was out. I'm cutting it pretty close.

Another option is to get your old sending unit rebuilt. That's not quick or cheap either though. I've been on the waiting list with MTS since August for a new sending unit. The old one is getting rebuilt. The quote was just over $400. for that, with a wait of eight to ten weeks. When all is said and done, the sending unit is one part that I'm going to have a spare for.

Are you still running a cat? Having a plugged catalytic converter gave me those same symptoms.

The old parts are removed and new ones ordered, so there's no going back. I just want to save the old sender and gas tank for now, in case they might be worth hanging onto.

My fuel pump was the problem. It wouldn't prime. Now I have a new Bosch 69302 set to go in. But everything in, and attached to, the fuel tank looks sketchy. So I'm taking Pete up on his advice about going through EVERYTHING while I'm working back in that area.

MTS apparently has my sender on backorder. My name's been on the list for over a month now. I'm considering having my old unit rebuilt. I might even keep it as a backup. The only option I've come up with so far is Instrument Services in Machesney Park, IL. Their ballpark is $325 to $350 and a wait of 8 to 10 weeks. Is anyone familiar with other rebuilders? Older posts in the forum mentioned Tri-Starr Radiator. They're out of that business, and sent me to Instrument Services.

My last battery tray came from Dirtbound, made specifically for an Optima. My new Group 34 battery is NOT an Optima, and I'm in the market for a new battery tray. (I'm keeping the old one on hand though, in case I ever go back.) Dirtbound isn't taking new orders at the moment. Anybody have any suggestions as to whose tray they like at the moment, and what makes it stand out?

The next time you place an order, you may see more color options available. Pete asked about the zip hoodie with both the front and back design, so we used it for our guinea pig. We were able to add a few additional colors, and there don't seem to be any negative side effects with the listing. So as time permits, I'll start going through all the CC apparel in the US market and see if I can give the membership a few more options. (Some of them are sure to make you stand out!) I don't think we've sold a single item on any of the international Amazon sites, so I probably won't bother trying to make any updates there.

Thanks for all the input! I'll just absorb the cost of this repair without bothering my neighbor for any compensation.
