I've been getting a smattering of oil/gas on the after-market chrome cover behind the fuel pump. I replaced the fuel lines within the last 3-5 years. Do the pumps leak? is it a simple replacement? Thanx, Dave

Try tightening the screws that hold that chrome cover on. Those screws(plus two more under the cover) also hold the fuel pump halves together, and if loose, can leak.


Crap I re-read your post...you say a chrome cover behind the pump? Gotta pic of it?
To answer the question, yes, the pump can leak, but they are not hard to remove/rebuild at all. I think the procedure is in the Service manual, which we have here.

The cover I was referring to is the triangular shaped piece that covers the gap behind the carbs. I'm getting splatter on the lower part of that cover that is directly behind the fuel pump.

Check other places on that side. I've seen some fork seal leaks that put oil in many places. One guy tore the front lower cowl off a GL1800 looking for an engine oil leak that turned out to be fork seals. I had oil all the way back to the rear wheel on my '77 when I bought it. Fork seal. If it was on the other side, I'd say shifter seal.

I did the fork seals last year and they made a mess everywhere. They're good now. This is low, behind the engine, right hand side.

Upon further review, I replaced the fuel FILTER, not the fuel lines 3-5 years ago. :oops: I'll replace the ORIGINAL lines this weekend. I hope its that simple. :beg: Thanx, Dave

I was getting some leakage from the tach drive cable in that area. As I recall, that was a new o-ring to fix it

When I installed my electric fuel pump, I accidentally left the two top bolts on the final drive inspection cover loose. That leaked. A lot.

:shock:

So, my cousin flew back to Phoenix Tuesday and so I used my day off Wednesday to take the stock pegs and shifter off and put my beloved after-market floorboards back on. Figured that would also be the chance to replace the fuel lines. Pulled the sidecovers off and don't really see where the moisture that sprays onto the right side could be coming from.

The left side, however, is a different story. There's plenty of moisture on that side.

The bike goes through a small amount of oil in the course of a season, maybe 3 or 4 half quart refills. uses no coolant. Getting the old lines off was a struggle, as I didn't want to remove the engine crash bars. I probably spent as much time as if I had removed them, but I prevailed in the end. Anything else I should look at on the right side? I'll take suggestions as to whats leaking on the left side, but my nature is to put the side cover back on and ignore it. :whistling:
Thanx, Dave

I was thinking the same thing as Joe. That would explain the oil slick on both sides.

Can someone show me what that looks like? Is it hard to get at/replace? Thanx, Dave

We had a member that had a leak in that area, and it turned out to be a folded rear cover gasket.

Yep. Looks like it is off the nipple. Could reduce oil consumption some, too. There is usually a catch can that condensate ends up in (if all is connected properly). You'll need to check and empty it each oil change. Finding new tubing, if yours is split, isn't easy. I ended up getting clear Tygon from Lowe's to replace the split tubing on my '78.
