Gas Tank Modification???

Post by marksa1458 » Wed Apr 16, 2008 8:18 am

I have been trying to track down a gas tank that will fit for ages.... After trying several jet ski tanks with no luck, I am now looking at an 8" diameter by 30" long poly "tube" tank.

In order for this tank to work, I will need to add a second filler hole to the tank. The On, Reserve, Return and Vent lines will go into the second filler hole and I would seal off the 1/4 npt line that comes standard.

My question is - Is it possible to glue poly to poly? and if so, how do you do it? I can cut out the second filler hole from another tank and attach it.

Mark,

My very strong reccomendation: Forget about trying to "fit something in". West Marine will custom build a tank to fit exactly where you want it (go look at the picture of my tank in boat-bill-der's "batttery and gas tank thread under small runabouts). Cost me a hundred and a half. maximized my fuel capacity, and cleaned up the whole engine compartment.

Peace,

TRM

Terry - You are right, by the time I muck with something it will end up costing more anyway. Through my whole build, I have been trying to stay away from anything custom... I think on this one it is the way to go. Thanks.
