I finally got around to putting a new fuel pump on my 48 today. I noticed that the road draft tube looks like it's got a lot of sludge in it. How hard is it to get this thing off the side of the engine so I can give it a good cleaning? I can see that its bolted to the oil pan. Is that all that holds it on?

OE, Right, that bolt and the tight fit in the oriface of the engine. In fact they stay in without the bolt. I think the bolt was mounted in order to assure that if it ever got knocked out of the block, it would dangle and follow you home. Just a little tapping will draw it out or loosen it up so you can pull it on out. Should clean up nicely and you can paint it and tap it back in. Piece of cake. Charlie

Thanks for the info. I'll get the thing out and give it a good cleaning and a paint job.

Tap it from front to back holding a piece of wood next to it so the hammer dosen't damage it.
this will loosen it up.
The sludge is between the two layers of the main tube.

When you get the draft tube off put it on hot grill for 30 minutes and everything will turn to white powder. Tap and brush powder off and paint.

Dougs,
Great tip. The ones I have cleaned up I have soaked in used gas. It is always quite a mess doing it my way and does require a lot of common sense like not using gas near a heater or in an area that is not well vented. All my cleanup work using chemicals, I do in the second story of my shop. It has a large window at both ends of its gambrel roof, and the ridge vent spans the entire roof. The only electrical device in use at the time is a CFL light bulb. I also do not store gas in this area.
Thanks, Mike
Thanks, Mike

I hope you don't get one that was in as tight as mine was- I tried being gentle, with a block of wood , etc, but after an hour, (and having a spare on hand), I had to get serious-
I ended up chaining it to the engine crane, applying some "lift", and then some persuasion with a big hammer, and it finally let go. I was removing it to see why I always had a small puddle of clean oil when I parked. It turned out that the baffle on the inside
of the block was missing.
