Hey all,

Have been reading for sometime - many thanks for all the help.

Having all the fun that you all do spending money and time on the beast (money pit).

I am wondering if anyone has attempted or can clarify if an ALTO fuel tank can be fitted to a MB?

Are they the same?

Cheers...

What I can tell is that the Alto tank is a different shape, (narrower and taller) and the mounting points are different.

Are they interchangeable? Not without a lot of work! A Hatch tank would go closer.

Does anyone know somewhere that will build a tank for the mightyboy?
Everyone I have tried cant or wont help?
I have tried getting the original from japan without much luck. I would prefer something new, otherwise A1 condition.
Any suggestions... :?:

Obviously your existing tank is in a sad way - you couldn't get it sandblasted (or cleaned REALLY well by some other means) and then get/put a couple of layers of epoxy fibreglass over it to seal it could you?

I'd NOT be keen on the idea myself, but I've read quite a bit about people doing just that on the 'net - from what I've read it seems to work ok... Apparently another idea is; there is some goo you can get as a two-part thing, that you mix up and pour into a cleaned tank then slosh about and allow to go off that will coat and seal small holes that is impervious to petrol...

If you don't want to do any of the above, there are people on th e'net who will repair your tank for you...

No Affiliation - first find on google: http://www.ftrs.com.au

Just some ideas...

About 5 years ago I sealed a pin hole with a blob of cement putty after cleaning the tank out and never had any problems..
About 2 years ago I took the MB off the road to fix some major oil leaks.
So for about 18 months the tank sat dry - this in hind sight has caused my current problem. A couple of months ago I got the car back on the road and neglected to check the fuel tank.
So a month ago due to bunny hops and excess fuel consumption (and plenty of reading on TAMON) I put a carby kit through - AOK.
2 weeks later fuel pump seized, took it out and found rust and shavings on diaphram, put it all together - AOK.
Took the time to clean the tank out and noticed it had rust every where on the inside which basically looked like sand flakes and piles of it came out during flushing.
2 days later pump stopped agian, this time the 'O' ring had split - got a replacement - AOK.
Now car is fine, fuel hoses and filters have been changed, carby and pump are clean. But unless I do something to the Tank problem is very likely to occur again. I have been able to locate tanks at wreckers only slightly better condition than mine. So to save all the trouble I would prefer to buy a new one or have one built. No Luck thus far.

Looked up FTRS will call tomorrow and get some Red-Kote and apply until I can get a replacement tank - will let you know how it all goes...

Thanks for the help guys... :|

The outside of the tank looks mickey mouse, so you would never think it could be so bad on the inside...

It might be the fuel line rusting out also. A friends Corolla had this issue - many fuel pump rebuilds and carby rebuild failed to fix the problem. I ran some compressed air through the line and blew crap out. It blocked up again so we just replaced to fuel line - problem solved.

I have thouth of that, but i get a great amount of rubbish and rust colour in the rear fuel filter and not much in the filter in engine bay.
How ever I would like to replace my fuel line - I have been told I can buy some from radiator specialists.
But Metal seems to have this inherent problem. Rust.
Does any know if rubber fuel line can be used instead? Are there legality implications or safety concerns with such a replacement? Does the hose diameter change pressure requirements or flow of fuel?

????

As soon as I can I will also put some pressure through the lines, thanks.

If you are going to replace the fuel line then use "bundy" line in either coated steel or alloy. The alloy is easier to bend and has less chance of rusting. ;)

You can buy this tubing by the metre from any decent brake specialist.
