Has anyone put in the gas tank from a EA81 wagon into a hatchback?My offroader started life as a 81 DL hatchback,so it was FWD so it already has the larger FWD hatch gas tank.Problem is I am missing the extra capacity of the wagon tank,the fuel gauge moves a little faster than I would like.So I am wondering if its possible to put a EA81 wagon (FWD or 4wd) tank into the stock mounting location on a hatchback.


Also if I was to say find a tank from an 84,would the sending unit work with my 81 DL's gauge?

As far as it fitting, i am not sure.Maybe with modification.  As far as it being different, yes, it is. The rear part of the tank and floorpan of the hatch and wagon are different. I would imagine you can swap out the sending units. But that is a speculation on my part. Mind you this was better than 10 years ago that i compared them.

Sending units are the same unless either is/was digi dash. I believe tanks are different. But you could make it work I'm sure by modifying the rear mounting point on th car.

Can anyone measure the length and width of their gas tank please?I have to cut out all of the rear "frame rails" to replace them with newer stronger stuff because my rear recovery points/bumper mounts basically got ripped out of the car.

i have done thiss i drilled out all the spot welds on the rear tank xmember moved it back to fitt and bolted it back in place took some time but very doabble might take a bitt of fabracating to make it look perty. At the same time i drilled out and tapped the return line 5/16 and added a internal spigot to put the returned feul back to bottom of tank. I take the spigot off a tbi fuel inlet and solder a tube to it then i have a threaded return line with a tube for in the tank. I also used the drain plug as my feul feed i used a bajo bolt and line from a automatic gave me a 3/8s feed line right off the bottom of tank strait to a volkswagon cis feul pump thiss works good supports my 2.5 turbo engine in my 79 wagon
