110 tank guard

One that works?

I don't understand your question. The usual arrangement is a matching guard that wraps round the tank front-to-back, with a hole for the drain plug to protrude. It's usually made of steel plate.

If there are others, I assume they're for off-road use.

Incidentally, when I changed the tank on mine a couple of years ago, I noticed that the dimple on the bottom (corresponding to the fuel gauge and outlet pipe inside) is a rust trap, as water gets between tank and guard and can't drain. I drilled a drain hole in the guard there and painted it before fitting, but I've no idea how well it's working (need another ten years or so!).

You can buy guard and tank separately, but it's best to fit them together (new parts).

HTH,

Me too,

I had a tank rust through so for the new one I undersealed the tank and tray where they meet, and drilled a few holes and injected that expanding foam stuff.

As you say - time will tell - but so far so good - though I do suffer problems with tank pressurisation and keep meaning to strip the cap down and figure out how it is supposed to breath.

I had this too on the TD and couldn't work out why, until the engine let go. I think it was related to blow-by upsetting the pressures somewhere.

Now TDi and it's fine...

If it is any help I had a 1990 110 CSW 2.5TD with a pressurised tank.

It is nothing to do with "breathing", mine turned out to be a split in a diaphragm in the high pressure fuel pump/distributor. This diaphragm takes pressure from the turbo and overfuels briefly when the turbo spins up.

There should normally be no significant pressure in the tank.

I hope that helps.

That may have been it. The whole engine was replaced when it blew a ring (or three), so I've a new pump etc. now and no overpressure.

The odd thing was that the fuel cap is the sort with sprung ball bearings in it for pressure relief. I stripped it down a few times in case it was clogged, with no apparent success. It doesn't seem that they work too well!
