The blower vent hose is rotten so I decided to replace it. I searched the forum and got some good advice and purchased some 15ml travel trailer heavy duty 3 inch hose. I tugged on the existing hose and it ripped in half behind the gas tank. Has anybody replaced the vent hose without moving the fuel tank forward? How in the heck did you do it? My fuel tank is full for winter storage and I'm looking for an easy way out. Thanks for advice.

I had to do it on mind, but had to slide the tank out a little to do it. It's pretty easy, even full, to slide the tank out a little on my '91.

If you can tie/tape/etc. a cord or a fairly stiff piece of wire on the old hose and when you pull it out the old hose you can pull the cord/wire with it, then use it to pull the new hose back up behind the tank and connect to the vent box. Otherwise, drop a cord with a weight on it or feed a wire behind the tank to pull up the new hose to the vent box.

Mine fell apart under the engine... it was tough enough to get behind the tank that I left it there. Mine had a piece of rigid PVC inside it along side the muffler so I spliced in a new piece of vent hose from the blower to the rigid pipe. Seemed like the vent up behind the tank was still in good enough shape.

the hose is a bit collapsed to fit back there, picture the wound wirey spiral can be folded onto itself like a slinky, if you can manually collapse it you should be able to fish it up and in, but it won't be easy with the tank in place. and since your tank is probably 20-25 gallons of fuel it will be heavy at about 6 lbs a gallon. My route would be to siphon the fuel into 6 gallon gas cans till it is light enough to slide into the boat a few feet.

Then you can clean back there, you will always find leaves and pine needles, atleast if you are in an area like ours.

And dead mayflies.

The tank capacity is 31 gallons. I know water is 8.34 lbs per gallon. With the weight of the tank + fuel it is approachind 300 lbs.

gas is about 6.22 lbs/gal...so only about 192lbs in fuel.

I had to pull my tank out a couple times for different things. It slides out very easily, even if it is full. It is also very easy to siphon the gas out of the tank (I do it to cars around my neighborhood all the time :D). Just buy one of these and siphon the fuel into your car, truck or gas cans to lighten the load.

I had to slide my gas tank forward on my 99 205 last year in order to get the fuel filter out of the tank to replace it. I am not very mechanical, so if I can do it, I'm sure you can to. Go for it!

heck sodar, you have a mouth don't you? Just when you see the fuel put the hose in the tank, and if you taste gas, spit don't swallow.

Gas varies in weight depending on premium regular etc. and on temp. It is far less temperature stable than water because it lacks hydrogen bonds.

hence you get more fuel if you fill on cold mornings than at 90 degree in the sun in the afternoon, and you are supposed to not top off to allow for heat expansion room to avoid overflow.

I did a thread on this:

If similar to 190, there is a hose bracket under the tank that will come off with two screws. I have a pic of this in the above link... I did not have to mess with the gas tank at all...


Enjoy,
