Hello, Long time since last conversation. Anyway my 200 AC has been sitting in my shop for many years since I bought it, I had all the bad internals replaced. Now that I'm retired after 44 years and my sons are married etc. I would like hopefully like to finish the project this year. I'm in the process of removing pretty much everything so I can power wash the 51 years of dirt and gunk off of it. I'm at the fuel tank removal stage now and I have it drained and blocked up. the fuel tank shut off valve now leaks  when closed off the stem a bit. I took the valve apart and noticed the o-ring. It looks more flat and square than round. Im assuming it's deformed from age. So is the proper o-ring still available or is there a possible replacement valve obtainable? Not through AGCO for sure. Also has anyone changed the plastic fuel lines on a 200? I noticed the (crossover) lines have some partially collapsed spots from being squished between the fuel tank and the hydraulic lines. So is it worth replacing with the original style line with the compression 
fit connections again or has anyone used rubber line and replaced the tank fittings with the barb style and used hose clamps and possibly routed the lines differently as to avoid line issues? I just don't want any leaks from the lines or the valve once I have the tractor painted and reassembled. Thanks for your thoughts. Larry.

Ive got a 200 that needs work to be serviceable but I havent touched it yet so I dont know what kind of plastic lines are on them. There was a plastic fuel return line on my 8070 that went bad. It was simple hard plastic tube. We get some plastic tubing frim Royal brass and hose that is two layered and is very durable. Id use it on anything

All the fuel lines on my 200 are the hard plastic type lines, supply and return. Just wondering if I should replace them when the tank is off and with what type.
Thanks

I think they are supposed to be metal.  If they have been sitting this long, best to replace them.  Plastic does not get better with age.

Anybody ever replaced any of the lines? And if so did you use the same type material line as original or convert to rubber fuel line? One of the under tank lines did turn in the connection but wasn't leaking at all.

I put new hyd lines and fuel lines on a 200 a couple of years ago when I had the fuel tank off. I used 1/4" soft copper but ran it inside 3/8" soft rubber fuel line for protection. The steel hyd lines going to remotes were not fun to replace.

Interesting. I also looked at the hydraulic lines and wondered if they were even available or would have to be made, yes definitely looks like a bad time. Thanks for your input.

As far as I know, those plastic lines should be available from most any Automotive parts store. They are used for fuel and air lines on many products. They should have it in a bulk roll and just cut off as much as you need. You will need new ferrules.

Whatever you do, don't use rubber fuel line in great lengths. After a while, the minute pieces of rubber break off inside and that spells disaster for injectors etc. Best to renew with the plastic line or I like the idea Leon did with copper line and using the rubber fuel line as an insulator for protection. Probably more expensive, but to me a permanent fix and excellent flow to the engine. Hence the reason for the plastic line in the first place...

In the case of the fuel tank shut off valve leaking when its closed do you think its probably the O-ring? or maybe the seat?  And is it a regular O-ring that can be matched up, or is it a special shaped one? I know it looks more flat at this point than roundish.

I noticed a bit of crud coming out of the valve when I took the stem out of the valve the other day to finish draining the tank.  Today I removed the tank from the tractor and used a wood dowel to see how much crud was in the bottom. A little bit, but not horrible. I'd like to clean it out further without using any water at all. Ive read a bit of E85 sloshed around and then drained will do the trick. Any other suggestions. Thanks.  Larry
