Gas Leak in Filler Tube

[Shadowman00]

I'm once again going to tap into the great minds on this site.

Over the weekend I filled the "Toy" tank on my WW. As I was filling the tank, I noticed that there was a leak in the fill neck. Gas was not dripping out, but there was a stead stream. Unfortunately I wasn't in the position to do anything about it at the time, so it just leaked. Yes I feel bad about the impact I had on the environment, but even worse about the $15-20 in gas I just lost.

I know I need to replace the fill neck, which looks to be about a 2" rubber tube. Luckily, it looks like the remaining fuel is below the leak level, so no more fuel is leaking. However now I have 2 questions.

1) We leave for a week long trip on Thursday. Is there a type of tape I can wrap the filler neck with to prevent further leaks until I have time to replace the tube? Would regular duct tape work or is there a special tape?

2) When I do replace, the tube goes through the floor of the trailer and then is connected to the tank using a hose clamp, there is about 2 1/2' exposed below the trailer. Rather than remove the entire hose and have to get into the flooring on the trailer, could I cut the tube and splice it below the floor, or am I better off to replace the entire thing, and go up into the trailer floor? Also, the current tube is somewhat rigid, not as plyable as standard rubber tubbing, is there a specialty tubing I need to get?

I'm relatively handy when it comes to these things, but I often don't want to pull things apart unless I have to. So if I can just replace the section of hose that has the leak, I think it would be much easier and less intrusive to the trailer, which could cause additional problems?

Any thoughts, suggestions, ideas would be greatly appreciated.

No glue involved with the PVC patch. Can be either black or white. Just cut a couple inches of your original hole out, slide the PVC into each end about two inches or so with hose clamps. Relatively little pressure on the coupling other than venting. JMHO

I've not had to deal with this as of yet, but I'd also be inclined to replace the entire hose. Since a part of it leaked, the entire run is suspect to me. I like the idea of a PVC replacement.

It was easier for me to drop the tank, rather than try to squeeze under floor or cut hole.Might do this when you come back and leave tank empty.Mine was fairly easy once the tank was down.

I would replace the entire hose once you trip is over. It'll be hard to get a barbed insert in and clamped on each end with limited space. You might disconnect the hose and insert a barbed insert into the old and new hose to fasten them together (no clamps). Then as you remove the old hose have someone feed the new hose through the hole without much of a problem.

You can buy it online (Amazon Prime) or even from Walmart. It's good with Fuel, Oil, Water and Air at big pressures. It's available in width's up to 2".

Thanks, I was hoping there was a "simple" patch system to hold me over for the week!

I like the direction your heading with this. However, when you say heavy wall PVC, my mind goes directly to the black PVC that is used for the black and grey tank discharge? Is this what your referring to? If so, is there a specail glue that is used on the connections, or will regular PVC glue hold up to the fuel? I'm just curious if the fuel will eat away the glue, I know it "welds" the PVC together, but will the gas eat through it?

The technical stuff is what I usually over analyze!
