Hi guys, just filling up the boat and noticed a gas leak. Upon further inspection I found the filler hose to the gas tank was rotted and leaking on top of the tank. The hose connection is approximately 1 1/2" diameter,will measure later to be certain.
There is only a small access circle on the floor to the tank which I removed the worn hose from the tank. My question is what would be the best way to change this as most of the hose is under the floor and only comes out just in front of the steering wheel where the dash is and than out to the side where the filler cap is. Any ideas would sure help,thanks.
 
Goood luck with this one...........I had to do one of these many years ago, different boat but the hose was in front of the passanger side seat and the tank was mid boat under the floor...........one of the LONG screws used to mount the passanger seat perferated the hose.........

What to do...... measure the hose very carefully, try to get the EXACT length + ~ 1/2 inch.
Remove both ends, attach the new hose end to the end at the fill side. Use a good quality tape and make sure you wrap it at least one foot on both hoses.

Pull the hose thru from the tank side.

Make sure you use TWO hose clamps on both ends!!

That is my best suggestion. All I can say the one I did was a real BIATCH!!!!
 
Thanks kg, have you ever heard of anyone using general purpose (pink/red) air hose as a fuel filler hose? ,I have a fair bit of that type of hose.
The first thing I should do is remove the filler cap flange from the boat than remove the hose from the barb and feed the new hose with the old one through the boat. What do you think?
 
that's why it got eatin by the gas not rated for fuel. Real a-hole who installed that hose. Your lucky gas is nothin to fool with use the real deal.
 
I think the hose may of been original,it"s a type of tank truck hose with steel wire wrap. I was just asking for a replacement hose and a hose supply store said the pink would be good for replacement. I also did not think so as well,that's why I asked you guys. Thanks.
 
You have to use coast gard certified gas fill hose!!!!!!! If you do not the boat will not be leagle and some one could get killed!!! NO SHORT CUT IN MATERIAL!!!

If you try the pull-thru method, I would opt for using a plastic hose to hose barb from the plumbing aisle. Use some good hose clamps to hold it together. I'd give you 20 to one odds that it will work and you may end up cutting out the floor. Aren't boats fun?
 
Hey guys,found some writing on the hose "FUEL FILLER HOSE 310 USCG". I'm sure that was the good stuff at one time.Thanks
 
USCG = united states coast guard. That is what you need to replace it with and nothing else!!

Any marine store will have it just make sure you measure the inside diameter.

good idea on the barbed plastic pvc and clamps.......it will be a biatch and some of the isulation will get ripped out but better safe with a fresh hose that not.

Just so you know, When I was in the business, we had a customer with a 24 ft old piece of crap cuddy, the kind of customer who did not have any money but wanted his boat to work. So just the minimum was done to keep it going. The other Mechanic who worked on it did what was needed. when the guy put the boat in the water he went to the end of our docks to fill up with gas, 60 gallons poured into the bildge and no one knew it was happening. The old fill line rotted out in several places over a few winters real bad as he did not use it that often. WHen he hit the key to start the boat...........it blew up!!
He had to jump thru a melting vynal bimini top to escape. The burning vynal stuck to his skin line fly paper.........the boat burned to nothing, drifted into other boats tied to the docks and damaged them also......it was a real mess to say the least.

Not trying to point any fingers but even proffessionals can and do overlook some issues that are not in plain site.

As a boat owner you own some responsibility to understand some things and if you are going to do work on your own boat it must be done right. Not like cars where you can cut corners and get away with it, IE regular rubber hose.....or worse, air line hose.....WTF!!

You did very good finding the problem so do the repair correctly!! If you can not then let someone who can do it, do it.

Shields, Vetus or Trident brand. I tried the stuff they sell on Ebay and it's real junk. Wasted $50. Spend the 7-10 bucks a foot it costs for the good stuff.


At least that guy put the hose in the fuel fill and not the rod holder.
 
Bought the right stuff,found a tight 1 1/2" nylon hose barb. One of my boys pulled the hose while I fed it through. No room for clamps but soaped the new hose as it was heading under the floor. Good to go. thanks for all your help guys . homerl.
