Gas Tank Leaks

[jfharper]

I have two 6 gal red metal gas tanks. They leak when the hose is not attached at the point where the metal thing goes into the hose. They didn't used to leak, but now they do. It looks like there is some sort of pin that pushes in when the hose connector is attached. The tanks both still look to be in good shape...is there some manifold or something I could buy to replace in order to correct the leak?

I don't see what I need there...but thanks.

mine are older metal tanks, they say parts OMC on them. It looks like I'll need something in the whole unit that includes the filter, tube, float, gauge, and hose connectors...this looks like a one piece unit that screws to the top of the tank...the fuel leak from the male connector when the hose is not attached. Does anyone know where to get parts for these older tanks?

Maybe I could get a second hose connector and a small bit of hose...then, close the hose off somehow. This second connector could go on the tank not in use...then when tank 1 runs out, I just swap the lines...the second connector would just keep the tank from leaking at the valve

Or better yet, attach a T to the existing fuel line and run a second line and connector to the other tank. Anyone think that would build up too much pressure?

Fix the tank already. If you look at the pins you will see a tiny brass washer around one of them. There is a tiny o-ring behind that washer. There are two core plugs opposite where the pins are. Remove the core plugs and the pins and springs will come out. There are two more o-rings in there. Once the pins are out, pry the tiny brass washer out and replace the o-ring plus the other o-rings. Stake the washer back in with a screwdriver and hammer.

There is one catch to this: There are two different sizes of tiny washer and o-ring. You will have to figure out which one (age) you have or buy both.

Parts are available from an Evinrude dealer.

PS. You have determined that the o-ring in the fuel connector itself is not leaking, right?

I see the brass washer, but it cannot be removed. The surrounding metal is holding it in...it looks like it was bent in with a flat head screwdriver 4 times, factory done no doubt.

Get in there with a makeshift dental pick type tool and pry out the brass washer, FR did say the washer had to be pryed out.
