Gas tank question on TCS
« on: Friday,March 03, 2017, 11:29:37 AM »
quick question -


Is it much of a pain to remove the gas tanks?

Cheers,

It's not bad if you can lift the car over three feet off the floor. You have to take off the covers that are pop riveted in the front of the wheel well. Then you can get to the bolts that hold it up. Of course, you have to disconnect all the "hoses" and take off the fuel fillers first.

Not on my TC, I followed the BDA route of dropping them through the floor.  If the engine is out or the cylinder head off there might be a way, I don't know.

You might not need to lift the car so much because you can twist/angle them as they come out, but it's still a significant height and the car obviously needs to be secure. I had some tall axle stands which helped, otherwise it's stacks of bricks or wooden blocks.

I have just put mine into a bare bodyshell, detached from the chassis.

There is no other way than through the bottom.

4 x 7/16" bolts and large penny washers hold them in place.

Prepare to lose skin undoing them. A small ratchet socket or spanner (wrench) is needed.

Even when they are loose, they are still difficult to get out or back in.

That's interesting and a very useful insight. If you can't fit them in a bare bodyshell then that certainly answers the original question !

Presumably it's the fibreglass which shields the tanks from the chassis/road dirt and cover the tops of the Y forks that are the problem, not enough space to wriggle them out ?

The tanks are big and just don't fit through the space into the engine compartment. If they did, I would expect they would have closed in the fibreglass below the tanks to stop them rusting from below.

But here we are 43+ years after most were made, and I have only seen many of the tank tops rust. Out of the 14 original steel tanks here, I would estimate 10 have rust holes in the tops.

I never liked the design of the original tanks. Having a steel tank with that "rolled" joint at the top where water can collect is just a bad idea. They should have used a better design but that surely  would have been more expensive. It would have even been better if they had been made of aluminum, but that would have been even more expensive and pretty far out of the mainstream for the time. All that at a time when Europas were already pretty expensive and they had their problems selling them as it was.

Having just today fitted the chassis to the body, the chassis does not interfere at all with the tanks.

The safest way to remove the tanks is unbolt the tank from the inner tub (4 bolts) and drop them to the floor. The tank is 21" tall so just guessing here, lift the rear of the car about 18" or so, enough to angle the tanks out from the body.

The picture shows my TCS on front ramps and rear cribbing in the middle of an engine removal. The underside of the body is approximately 14.5" off the floor. I estimate one more layer of cribbing (4"or 5" of additional height) should be enough to allow removal of the tank with some wiggling. If you have an engine hoist, use that to lift the rear.

This all going on old memory from several years ago when I installed the gas tanks on the Cosworth. The maximum height required should not be greater than the tank which is 21".

Joji, please do not go under a car supported that way.  If someone slipped and fell against it, it would come crashing down.
