New filter installed, but didn't make the difference (it makes me feel better having a proper fuel filter with water separator). Injector removed and it indeed had a lot of carbon build-up on it. I did some cleaning, but couldn't get the bugger disassembled. As it was, it barely came out of...

I pulled the fuel pump assembly open...the strainer and gasket looks like the spitting image of the part they're still selling, so I bet they're still compatible. There unfortunately wasn't much to clean off the strainer and the inside of the pump also looked pretty clean. After reassembly and...

On the HMMWV, a pretty good rule of thumb for me to follow has been: Does this component thread into the engine, transmission, or transfercase? If yes, it's almost certainly metric. Almost everything else on the HMMWV is SAE. The gray area is going to be on modification/accessory installation...

Let me make sure I actually need one first before you dig too hard. I have a chance to turn the wrenches again tonight to check it. I also have a proper fuel filter arriving tomorrow I'm case it's not the pump. Sent from my Nokia 6.1 using Tapatalk

I personally own a VFC Mk16Mod0 SCAR-L. It's absurd how closely they replicated this to the real thing, right down to barrel take-down and receiver disassembly. I got a chance to handle one just before they released them to the public and had a guy on base laughing when I knew exactly how to...

The idea's not original. This fella in this post chose to modify his fuel cap that's always in-place: https://www.steelsoldiers.com/showthread.php?127621-Ran-out-of-fuel-on-a-HMMWV&p=2089635&viewfull=1#post2089635 (Post 26 a few posts down shows it installed) Same method here, except that I...

Oh man, sorry to hear about the loss. I used to love getting into airsoft skirmishes year ago right up until it seemed that all of my gear broke down at the same time. I really want to get back into it some day (still have all my gear) and have a real blast rolling out the HMMWV onto the field...

You can really do a lot with the standard tool kit. Flat and Phillips screwdriver, adjustable crescent wrench, slip-jaw pliers, and your tire change tools (lug wrench and jack). Fuel spout and fuel can is nice, too. I've overhauled the coolant system roadside, adjusted mirrors, tweaked...

Mmmm, Mets. Where's that HMMWV with the grill attached to the back of it? Sent from my Nokia 6.1 using Tapatalk

I had this issue, too. I was able to sneak a rivnut in there just right to get it hold in place. If that fails, you can place in a wellnut that will expand a bit larger and should hold up a few years before the rubber dry rots. The wellnut was actually what was there when I picked up my...

Nice! While looking for information about the fuel pump, I stumbled upon the patent for the exact heater I'm working on. Funny enough, the patent literally expired today. https://patents.google.com/patent/US4276018 The attached PDF has multiple detailed drawings and the dialog of the patent...

You're the best for taking the effort to look for that, even if you end up not turning up anything. I did find an army TM that covers another piece of equipment that uses the same engine. It's been helpful at understanding some of the operations of the engine that weren't covered in any repair...

Here's a compliant source for what you're asking about: https://www.hummerpartsguy.com/SPRING-FRONT-1728LB-SNOW-PLOW_p_123.html That said, I haven't done much work with springs, but definitely can tell you that higher spring rate would likely be miserable and actually probably cause issues if...

Learned that my QP-1800 inverter won't drive my air compressor. Then again, I think something is wrong with my air compressor. It'd throw the breaker every time I tried to run it on the HMMWV, and kept burning out 20A fuses on my garage breaker until I decided that it needed to be placed out...

Curious...did you ever find the actual culprit? I'm always wanting to know what little bugs show up in the 4L80E transmissions since I am troubleshooting a problematic one over time...

Looks good, but I have to ask: you're deliberately leaving out the side reflectors? What for? Sent from my Nokia 6.1 using Tapatalk

What to do with the air filter is straight out of the Hatz Repair manual: In short, sounds like I need to actually pull this off the engine to get a clearer picture of how to disassemble the filter, as there should be both a removable and non-removable filter element-I'm likely hung up on the...

Alright, so I've gotten a start on getting truly hands on. Drained and rinsed the tank with some fresh fuel, changed the engine oil (well, it had no oil. I just ended up filling it), and attempted to change the fuel filter unsuccessfully (more on that soon...). Slaving off of my HMMWV and...

I just brought home an older ground support heater, NSN 4520-01-056-4269, manufactured by Davey Compressor Company of Cincinnati, Ohio. It's definitely a bit rough around the edges, but it looks like all of the essential equipment is there and in-tact. The hour meter reads out about 1400...

Machine recovered A-OK. It's a bit different than the machines I could find manuals for, but doesn't look too different to be and to figure out how it all works, especially since the fuel diagram and wiring diagram are both right on the housing. As I expected, fuel smells and looks bad, so...
