I just this weekend completed changing the fuel tank in my 1981 C&C 34. It was 
not worth the risk to attempt to repair the old tank particularly having to cut 
off the filler neck. My tank was 19-20 gallons. Moeller Marine 
www.moellermarine.com makes a USCG approved plastic tank that in my case 
literally was a drop in in terms of dimension and location of the fill, vent, 
and fuel line fittings. It came from AMAZON. Ordered on Monday, delivered on 
Thursday with ground delivery and the total costs including shipping was less 
than $160.00. If you have the old tank out, it makes no sense to try to fix it. 
Trident Marine http://www.tridentmarine.com/ makes a more flexible fill hose.

Well, it was a cold weekend, but I wanted to check the boat, make sure there 
was no water freezing up inside, and if I'm going to drive down there then I 
may as well get at a job or 2.

Stripped off the last bit of upholstery - now I can get all the cushions 
re-covered

Then I tried to remove the fuel tank.  Let's just say the tank was not in total 
agreement with my plan, and as such the process was a little more violent that 
I had hoped for - I had to cut the inlet and vent pipe (but I figure that 1986 
hoses are likely due for replacement - so it was not a huge loss.

Once I had everything disconnected I lifted the mostly empty tank out of the 
lazerette - and saw a small pin-hole leak stream out on the top of the tank.  
Right where one of the metal tank strap tighteners was resting - clearly the 
contrasting metal had corroded a small hole.
Otherwise the tank looks good.  Just dirty.

I need to clean the tank up to get a better look - but I'm wondering how this 
should be repaired.
Given I wanted to clean out the tank and install an access hatch (but near the 
other end of the tank) - should I get a small patch weld?
Or did I read somewhere that a fuel tank can be lined with epoxy.

I feel like I could even just drill out the hole, tap it and screw in a small 
bolt with a gasket.

I'm stiff after a few hours in the lazerette fighting with the fuel tank
- but the new boat shine has not worn off yet!
