Default Onan MDJE - what is this part?

Hi,

Can someone help me to identify this part that is left over from my rebuild?
It seems to be either an oil coupling or fuel coupling but I can't figure out where it goes.

Cheers,
Mike

Looks like part of the fuel return line.

Maybe it screws into the block and the oil pressure gauge threads on to it??

My guess,,, oil line restrictor to limit oil flow to the cylinder head?

Looks like this to me, fitting into the injector, but you must have started off with a spare if the generator is assembled already. Cheers Dan

Many years ago, while still working in the shop (before I got to venture out in public) we'd play with each other and slip in an extra part or two for the mechanic to "find" when he had the engine most;y together.
Sometimes they catch on right away and toss out the extra part. A couple of times they'd start to take it back apart. Valve keepers were a popular "spare" part for this. Pretty obvious if you slipped them a conrod or oil pump, but an oil pump drive spider was good too. Some guys had no sense of humor, some did, one guy threw a real fit and was left alone forever.

The "extra parts" gag is always a good one, BUT I always thought it was worse to not have ENOUGH parts... Now you're left wondering what you put where it doesn't belong This gag works best with things such as automatic transmissions or anything with lots of thrust washers that are easily mixed up

The worst is trying to put together cheap-azz furniture made in China. When reading badly translated directions with piss-poor pictorial drawings where all washers and screws look alike in the drawings and trying to match up the actual hardware, I always seems to have left overs.

Then you get those cheap-azz allen keys that come with the cheap-azz furniture accidentally in2 your tool box and wonder why you twist, break and strip them

Wow! dead on about those cheap-azz allen keys. I also hate when I overtighten the cheap-azz allen bolts which pulls those cheap-azz stud nuts out of the cheap-azz fake particle press board too.

That's the one!!! The injectors are still in the specialist workshop being reconditioned. I must have left one of them off when I handed the injectors in. Well spotted BigBlockChev!!!
