Fuel tanks

[skull85]

Hello all, I have a 2005 Marlin, and wondering if at some point in time I should replace my fuel tanks pro-actively as a preventative maintenance effort. If not what about the fuel system outside of the tanks - fuel lines, venting lines etc... Thanks all.

20 years on lines? Sure, that's acceptable to do as PM.

Tanks? All depends on the conditions and maintenance it's seen. Inspect well and then decide.

20-25 years is about the average life expectancy. with a job like that, its definitely better to do it at a time of your choosing rather than mid-season

I have same concerns with my 2007 Sailfish. Dealer suggested a pressure test on tank while it was in for service. I forget what psi the test brought it up to and for how long, but it seemed pretty high to me. Anyway, it 'passed'. Service manager said that if there were any questionable spots on the tank, the test likely would have created a leak. So they tell me after the test.

So I'm hoping I'm good for another two years there and maybe I can think about a repower - if I can get over what is sure to be sticker shock.

2 or 3 psi is appropriate

20 years ago GW didn't do the best job insulating the contact points for the tanks. The adhesive on the neoprene strips breaks down, strips move and trap water. Over time this corrodes the bottom of the tank. Even the top of the tank under the mounting blocks. On my 268 Islander the steep had to be cut and a bulkhead removed/replaced to get the forward tank out. Hoses are difficult to replace with tanks installed. Tanks are a maintenance item. If you are going to start poking around it's best to just commit and replace it all.
