1988 GL1500 Fuel lines

Post by Geowing66 » Mon May 07, 2018 9:16 pm



Hello all,
A couple of years ago I had my carbs rebuilt at a Honda Shop because of a fuel leak that I assumed was a sticking float. It started leaking after winter storage and I started up the bike for the first time that year.
Fast forward a couple of years and I started my bike up for the first time this year and took it for a ride and noticed a strong gas smell.
when i got off the bike I notice fuel running down the engine and onto the ground. i opened up the fuel tank door and there was a river of gas pouring out.
Today I took the air box off to find the leak and the fuel line was barely holding on to the inlet tube. as soon as I touched it gas started running out.
The fuel line and the clamp are shot. my thought was if the shop rebuilt the carbs, why wouldn't they replace the fuel lines.
Anyway my question is can I take off the top of the carbs (air-horn) to make it easier to replace the fuel lines?
the one that fell off is the one under the air-horn. Also what size fuel line do i need? I think it is 3/8".
Thanks guys
Keep Riding.
Geo

Hello Geo,

Would you have some pics avaialble?
I went through the same (nice) work of lines replacement 2 weeks ago. But I don't recall any air-horn on the top of my carb. I only have a plate where the air box is fixed.

Cheers,
Gilles

Yes that's it. The plate where the air box is attached to.
Did you pull off that plate?
Sorry no pics available at the moment.
Thanks.
Geo

Yes, I had to remove this plate to access one of the lines which was damaged.

Now my 2 cents: if you have a bit of time, why not taking the carbs out, and check/replace all the lines and clean the carbs?

There is a high chance that you won't access them for a while once the lines will be repaired, so why not taking the opportunity to have a look at them?
It might be quite painful to be honest, in particular when plugging back all the lines and cables.

If the carbs were rebuilt a couple of years ago, I would recommend not touching them at all, outside of replacing the fuel lines which you are about to do. When it comes to getting that deep into the bowels of the bike, my motto would be "if it ain't broke, don't....". I just did carb kits on my '92, and it is a big job, but it is doable. My carbs were surprisingly clean, next to no residue in the float bowls, kind of unusual, because it had been sitting for a couple of years before I got it in '2013. If your bike was running fine before, I would say just change the fuel lines, and keep on trucking.
