Welcome to the SS forums!!!

Well we all assume it is a HMMWV, I am going to guess you have a M1097R1 with a GVWR of 10,000lb by the serial number, this makes a significant difference. BTW your truck is really not a 2007, it was rebuilt to M1097R1 standards in 2007, most likely it started as a 1980s/early 1990s M998 SO...

You can get it directly off of the alternator output lead

What vehicle do you have?

The sending unit needs two things, a complete path (wire) to the gauge and the sending unit must have a good ground, the tank is plastic.

Welcome to the SS forums!!

That contactor going bad is a fairly common issue, post a picture of the data tag on your PCB box as it may be on of the ones that should be replaced because of its age. You will eventually have issues with the rest of the box but might get a few more years out of it, there are other options...

Remove the PCB (EESS) box and open it up there is a contactor (solenoid) inside that LOOKS the same as used for many starter (edit and winch) applications, it is 24V and should be rated at 100A AND continuous duty, do not cheap out on this part buy a good brand name contactor. The heater fan...

Dang I did not realize the 6BT weighed 320lb more than the Dmax... it is however all cast iron which does have its advantages. The Dmax only weighs about 80lb more than the 6.5T, adding 400lb will be noticed.

Spring side goes in. solid face goes out

The TPS has absolutely nothing to do with the fuel system, I suspect your "mechanic" has less knowledge than you think, Coug (and others) have given some good advice, until you positively ensure the glow plug system and plugs are working correctly throwing money at it will not get it fixed.

They are not that hard, you don't even need any special tools, I am 66 and 3/4 broken down and I can still get them done no problem.

Interestingly enough there were some van or bus applications that used the 6BT and a 4L80, that adapter angled the engine for clearance, I wonder if that would be useful in a HMMWV conversion???? I have no idea what mods were done to the engine as far as oil pan/pump pickup that may have been...

A basic M998 weighs about 5200, 4L80 180lb, 6.5L 750lb, so the starting weight of a basic or A1 without the engine trans,exh would be around 4200 as Coug said the later the truck the more basic weight

I have cruised a few Cummins sites and it looks like an expensive adapter. the common wisdom is without allot of upgrades the 24V will tear up the 4L80 because of the massive torque...
