Leaking fuel tank 110

So my 110 decided to randomly start leaking fuel from the seal near the front mounting bolts.

My truck had been sitting for a year with an empty tank and then i filled it and a few days later this started. Is it common for the seals to go bad from sitting?

What is the easiest way to fix this? I assume I will have to drain and drop the tank and then split the tank and lay a new seal? Or will it make more sense to just buy a new tank for 250$?

Drop the tank. If there's no rust it's probably the fuel pump.

As a temporary fix, there are epoxy puttys made as a fix.
JB Weld Stik Epoxy Putty (2 oz.) 8267-S: Advance Auto Parts

Long term, replace the tank.

Make sure you figure out what kind of tank you have there are two main types of early units. One with a hole in the top and the filler (two hole) and one with just a filler hole.

The two hole type needs a spill rail return top fitting installed, I know this cause mine just started leaking at the corroded top fitting and ill be swapping tanks just like you soon.

before I install my tank, I reprimed and painted it, then I give it a heavy coating of rattle can truck bed liner all over the bottom, along the waistline seams and filling in the top of the seam. the bottom tends to rust from water and mud trapped between the tank and cradle, as well as moisture getting between the seams or standing water on the top irregular surface of the seams.

Mine already has the drain bolt, which is sweet, makes draining it super easy.
I pulled the tank a little over year ago, so it is super easy to install and uninstall with all new hardware that is there.


Mine has the sender unit on the side and the tube on top. I think its just like this one from Atlantic British Fuel Tank for Land Rover Defender 110 300TDI | eBay

You can swap senders around. Mine had a sender in top, but I turned that into a return and put a new sender on the side.

agree. the side hole can have a sender or sender with pickup tube. the top hole can have a pickup tube or pump with pickup tube and sender. it's like a Lego set.

I'm about to swap out my 1 year old petrol tank for a diesel tank. my diesel tank is drying in the driveway with fresh paint and bedliner.

Leaving a tank empty is when/how they rust.

There is no seal between the 2 halves of the tank.
The tank has two halves that are stamped out and then welded together by a special seam welder.
You need a new tank my friend.

well I pulled the tank and it seems like it was leaking from where the sender was.
The inside seems okay, but since this is the second time i pulled this tank, I'm putting in a new one, so i wont (hopefully) have to do it again.

So the one from Atlantic British seems to be the same as my current one, so i'm probably going to go for that one.

Anyone want a used 110 diesel tank?
