Clog drain tube

nymack66 · #1 03-10-2009, 12:02 PM

I have a clog in the drain tube which runs below my fuel tank, I am not sure what it is since the electrical snake (stiff manual wire) refuses to clear it.
During and after my hull rebuild it was clear, I went Boating and during my wash down observed the water build up.
I am now convince I will tear out the hatch liner below the deck to expose the tube in such a way I can insert a small copper tube to clear the line.
Has anyone ran into an issue like this ?
Below is a photo with the old tank removed and cleaned.

Threw mine away when I redid my fuel tank. With your bulkheads glassed all the way to the hull you're gonna get that compartment full of water and have fuel tank issues. I'd leave a gap at the bottom of the bulkheads and chuck the pvc tube.

If you haven't already removed the tube, shove the fishtape in as far as it will go, add a couple of feet, cut it off and connect to a battery drill motor.
You may have to rebend the end either smaller or larger either to "drill" thru or dislodge the obstruction.
Rebending is easy with a small propane torch. Everybody needs a short fishtape anyway, also.
There is the possibility the tube is pinched or kinked somewhere.

Drill trick sounds like it would work.

Thanks guys I will give it a try this weekend, I have to remove the hatch liner to get complete access to the tube, of course I broke my thumb nail off in the process whilst this heals by Saturday, I will use my small angle grinder to cut the sucker out!
What started out as a simple issue took on a whole new turn !

I do like bradford's idea of doing away with it, reguardless of the outcome.
