Mep002a stuck fuel injector line

[trooper632]

Hey all, I'm in the process of trying to get my mep002a up and running after about 6 years. First off the fuel that was left in the tank was nasty and was gummed up in the tank, cleaned all lines and made sure clean fuel is going from the tank to the filters and to the IP pump, and fuel returns back to the tank. Problem is one of the injector lines is frozen to the injector. It wont budge the other one came off with no issue. I dont want to break it, I've even applied some heat to it to no avail.

What the best advise to try and free it up. On another note the IP pump seems to be ok as it pumps fuel out but it wont start I'm sure because its only getting fuel to one cylinder. Also dont think the glow plugs are getting hot. Where would be the best place to buy the plugs, they seem to be pricey on ebay.

I would liberally soak with Deep Creep, give it time, and a few thermal cycles with a torch. Rinse and repeat.

Deep Creep is a penetrating oil and lubricant that quickly cuts through rust and buildup of all kinds to loosen, lubricate, and protect parts and mechanisms.

2nd that! There is literally nothing mechanical stopping it from coming out, just lube, heat and a little vibration wouldn't hurt.
either tap on the hex part of the fitting or very gentle vibration from an air hammer with a flattened chisel will do it.

Glow plugs were available as of last year, I bought a box of ten Champion 182 CH42 glow plugs online. I don't remember where they came from but do a search for CH42 glow plugs.

I do see that the glow plug washers are the same problem as the plugs, Expensive and/or unavailable. Looks like you have a couple choices from McMaster-Carr. A 97725A100 has a hole just a hair small but outside is good and the 97725A228 Which has the hole good but outside too big. I think it would be much easier to shrink the outside on a belt sander than it would be to try to hold a copper washer and drill it out.

I believe they were on ebay. I recall you sharing the link, seller had 10 packs for $150 but it looks like they are now gone.

I KNEW I should have bought several packs!!!

Does anyone have the thread size, and length on this glow plug? Just curious.

Champion says 10mm 1.0 but I find that fairly hard to believe.... AND here's more proof that 10 x 1.0 is incorrect!
