Fuel leak

Postby DarthJ » Thu Sep 01, 2016 9:12 am



What a fun morning. When I went to bed, everything was fine, woke up to gas smell and fuel leaking from what appears to be the tank on my GL1500. What do you guys see?

I'm draining the tank and will be removing it to look.

The wet spot seems to be up the left side. I would follow it up as far as it goes and see if you can see where it is starting from. You will have to remove the seat. It very well could be a hose at the top of the tank where it leads to the fuel pump.

Let us know...

Already have the seat off, I don't see anything wet on the top, but I'll trace the lines to double check.

aaaand found exactly where she's leaking. On a whim, I used a shop towel and wiped the fuel off the area. Came RIGHT back and I saw a tiny hole just big enough for fuel to come out. I have it highlighted in the picture. Click to see it full size and note the circled area by the arrow:

Ok, yup see it. A leaking tank itself I've not heard of before. Don't know what would be a good fix for that other than replacement. Hopefully someone smarter than me will check in to offer a great fix to the problem.

Hope not, Rob, they're $651 out of partzilla! :shock: But it is what it is, at least my truck gets an extra 5+ gallons of gas :lol: (It always seems to happen with a full tank, doesn't it?

Pull the tank inspect for rust, pitting etc. if It looks good otherwise weld the hole..it looks like it could be in the seam or am I seeing it wrong. Or a good sealer like POR15 and weld.

depends on your pocket book..what's cheap???

Not on the seam, the hole is a small bit above. Finally stopped dripping fuel, (always has to happen when full, why not when empty?) so I got a pic of the clean dry hole. It looks like it rusted from the inside out.

Rusting from the inside out. Patching the hole will only be a temporary fix.

Thanks, Tom. Obviously not what I wanted to hear, but does confirm my own observation. Time to see what I can find.

I'd do the Permatex thing and start looking on ebay for another one. That way you won't be without while you are looking for replacement. Then, before replacing clean and seal the inside of the new one to make sure it won't happen again.

We've always used Permatex "black" gasket maker, in a tube (we always referred to it as "gorilla snot"). It's NOT a silicone-type material - it sort of hardens, but remains somewhat pliable. We sealed a 1/4" hole in the bottom of our rally car gas tank with it, sealed up a rather larger hole in the alloy sump of my own rally car, and neither of 'em ever leaked again (and we never repaired them!). Back in the day, I had a Yamaha TX-500, and I used the Permatex black on it all the time. The left side cover had to come off at least once a month to service the many, many chain drives inside (5, IIRC) and, as gaskets for the side cover were no longer available, I used nothing other than the Permatex. Even though that cover held back extremely hot oil, at fairly high pressure, it never leaked a drop.

I even sealed up several small holes in the (aluminum) diesel fuel tank on my boat with the stuff. Someone had left a handful of galvanized steel screws sitting on top of the aluminum tank - electrolysis made the screws "melt" right through the top of the tank. That was about 14 years ago - there's a LOT of fuel pressure against the patches but, even so (and even going through some rough seas!), it's never leaked. Not even a trace. Funny - the boat yards I spoke to insisted that only replacing the tank was acceptable. Unfortunately, on my boat, it would have to be split down the belt line & the top half of the boat removed, to get to the tank. As the boat's a 30 ft. turbo diesel cruiser with a command bridge, separating the boat that way is not for the faint of heart. The cost of replacing the tank was estimated at roughly twice the value of the boat. I did my own patches instead ("gorilla snot", stainless washers, & stainless screws into the holes). An old-time marine mechanic I trust took a look at the repair. His opinion? Consider it a permanent fix, and forget about it from then on. 14 years later, it appears he was right!

Personally, if I were you, I'd probably see if I could access the hole with a drill & small drill bit. I'd open up the hole a bit to remove all traces of rust (**hint - magnetize the drill bit first, so drillings & rust cling to it & get removed, rather than being chased into the tank), then patch it with Permatex (which will also prevent further rust). For peace of mind, a swath of Gorilla tape over the wound & Permatex (a Band-Aid, if you will) will keep the area clean & dry. That would keep you on the road until you can get a replacement tank (or, forever, if you chose!).

I should add that, from the moment you press the Permatex on, the leak will be sealed. The seal will only get stronger with time. A warning though - the stuff is MESSY, and gets everywhere (like NeverSeize does....except that this stuff doesn't wipe off!!). Wear an old shirt, and keep rags handy. BTW, the stuff is actually very dark brown, rather than black.

Just my $.02' worth.
