fuel lines
 

The boat i bought has been sitting for a few years so i am going through the boat to bring it back to life. I removed the hatch above the tank to check condition and clean the tank out. The hoses are in very bad shape so will be replacing all of them. Does any one no how long the hoses are? I would like to buy new hose before removing old if possible.

You buy it by the foot. Just get more than you think you need. When you take the old hose off, cut the new hose to that length. In my '82, the tank in the floor back against the transom. Conservatively, I could probably plan for 18" from the tank to the water seperator. Another 18" from there to the shutoff valve. Maybe 4 ft from there to the primer bulb. Then 2 feet to the engine. 10 ft would cover it, I think. More if your tank is further up or if you have multiple tanks.

my tank is in the floor. vent and filler look to be about 6 foot the engine line looks to be about 10 foot to the filter then another 4 to engine. also i did not find any foam other than around the tank under my floors. my v20 cuddy is an 86 so i was expecting to find flotation.

Sounds like mine. Like aw says, measure and get enough (i.e. plenty). I'm real glad I pulled a pull-string in with the old line when I pulled it out (I pulled it out from the back). I fed the new one from the front and had someone pulling the string from the back - it was a bit of a fight, but it made the boat run again.

I guess thats what i will do is pull old ones out with pull ropes then measure. did not realize how expensive fuel line and filler lines were, much more than i expected.

If you think thats a lot SELL NOW!! It only gets worse!!

Have some pics lines were in the water. I am going to rout the new lines through clamps near the top of the stringers. I might move the vent also.

Boat is a an acronym for: Bust Out Another Thousand

Wow, that there is some rotted fuel lines.

Are you removing the tank, inspecting/ replacing? Maybe wait then till you know that the connections on the tank will be in the same place. Like you said, hose is expensive and a half inch too short might as well be a yard!
And you can't leave extra cause the gas will pool in the hoses and cause filling/venting problems. Oh and wear long sleeves if you don't want to trash your forearms....
