Fuel filler hose replacement
 

Fuel filler hose in my 1973 23'cc must be replaced. Any tips on the best way to do this?

No one has ever had to replace a fuel fill hose even with the addition of ethanol to gas??? :D

Re: Fuel filler hose replacement
 

Been there, done that.
Use a hose nipple and clamp the old and new hoses together at the gunwale. Don't cut the new hose to exact length until it's in place. Then pull the new hose into place using the old hose as the guide/snake. Make sure you clamp securely. Simple. Not easy, but simple.

So what you are saying is to thread the inch and one half I.D. hose DOWN from the gunwale to the tank after connecting it securely to the old hose? I have connected the old and new hose with tie wraps and have been trying to pull up from the tank to the gunwale and it's just not working.

Re: Fuel filler hose replacement
 

Yep. Tie wraps won't do it though. You need wire clamps or worm-screw clamps as well as a two-ended hose nipple to connect the two hoses. I have done a few of these over my 40+ years of boating. I have failed to bring a hose up from the tank once or twice. I have never failed to pull one down from the gunwale.

Oh yeah. It's easier if the tank is removed.

Job done. Brought the hose up from the tank with tie wraps connecting both inch and one half hoses. Secret....spray lots of SILICONE spray on the hoses, near the connection. Slipped right on through up to the fill port on the gunwale.
Next, I have to do the vent hose.

Re: Fuel filler hose replacement
 

I have to do the same mod. I'm curious how you do the vent hose.

Any recommendation out there?

Re: Fuel filler hose replacement
 

The only way to pass that vent hose is by cutting a small (4") inspection port at the top inside left of the strut/conduit that runs from the deck to the gunwale where both the fuel filler hose and vent hose pass through. There is no way to pass the vent hose through the small right angle hole at the top of the conduit with the new hose connected. That hole is just about the same diameter as the vent hose. It then takes a sharp right angle and connects underneath the gunwale out the side to the vent port. I'll let you know how I make out.

Re: Fuel filler hose replacement
 

Vent hose is in. A messy job putting both these hoses in but
it needed to be done. Ethanol in the fuel really did a job on the fuel filler hose. It was more or less rotted out.

Re: Fuel filler hose replacement
 

JFM, did you have a hard time getting the hose loosened from the foam from the filler cap to the tank? I put in an inspection plate to access the 1 1/2" fill hose and the vent, but can't seem to break the filler free. Any suggestions? This is kicking my butt!

Re: Fuel filler hose replacement
 

MARLIN...I did not have any foam around the fuel filler tube. Just the 4 bolts holding the filler tube in. Those were difficult to get at but I was able to remove them. I just undid those 4 bolts and pulled the filler tube up from the top of the gunwale. The boat is a 1973 CC.

Where did you cut your 4" diam. port. Upper or lower area?

Point "B".

Thanks!

Your conduit that runs from the deck to the gunwale is similar to mine with the exception that your gunwale cap extends down further than mine. At the top inside left of that conduit I have a hole that is just a little wider than the vent tubing. The vent tubing comes out there and makes a 90 degree turn and connects to the vent, (overflow fitting), on the side of the boat.

Just don't get any Silicone on any primed surfaces waiting for paint.... :( Fisheyes

Re: Fuel filler hose replacement
 

Nothing to paint. The hoses are inside a conduit. ;)

Re: Fuel filler hose replacement
 

When I replaced the fill and vent hoses on my Tsunami,I figured that it would be a nightmare.
The opposite was true.After I pulled the hatch cover,cleaned,inspected,and re-installed the tank,it was just a matter of connecting the new hoses to the old,with a a piece of tube and some hose clamps,and pulling them through.

I removed the fill port,and pulled the old hose,and new hose out from the tank,under the deck,and up the pillar,to the gunwale as one piece.Discarded the old hose,cut the new hose to length,and attached it to the fill port,and tank and re-installed it.Did the same with the vent hose.
Other than a little bit of a PIA getting at the screws,it was pretty easy.

Re: Fuel filler hose replacement
 

You didn't have to cut a hole in the pillar to install / gain access to change out the VENT TUBE??

Re: Fuel filler hose replacement
 

Nope,the vent went out pretty high.I was able to get to it,by reaching up under the gunwale,just to the front of the pillar a little bit.I had to go down,with my hand a bit,then I was able to push it up,and on.
I did cut up my hand a bit on some rough glass,but i was able to slide the hose on to the vent and clamp it.I don't know,maybe I just got lucky.

Here's where my vent is,you can see it,just under the blue horizontal scaffold tube.It still has the masking tape on it,looks like a nub.

Re: Fuel filler hose replacement
 

You're fortunate. Vent hose on mine came out of a small hole at a right angle near the top of what you call a pillar. Could not reach it by hand, let alone get it through that hole and out to the vent fitting on the side of the boat. Had to cut an access port to get at the vent hose. Fuel filler hose was pulled through to the top of the gunwale with the old hose. My tank remained in place during the procedure.
