If that's a fuel pipe I wouldn't be using a jubilee clip on it. They tend to pinch in one area therefore leak. I suspect over the years it's been changed and the original correct type has not been replaced. I would use a fuel hose clip. I would also think that may not be totally correct. It may be an ear type clamp or even a push fit that goes over the shoulder. ETKA may show the original type of fitting/clamp used.
Following a clear out I have some spares that I'm not going to be using. There are a couple of auto gearboxes. At least one of each 1.6 and 1.8 engine block. There are a few cylinder heads, at least one of each, 1300/1600/1800 let me know if you want part numbers. Odd engine parts. A couple of 1.6 toilet bowl down pipes and some odd exhaust parts. A box of Pierburg carbs in pieces. Then there are some interior parts, odd trim bits. I think there's a passenger seat, rear seat(one part but not sure which), original grey seat material that's been removed but may only be good for spares or repairs. Some blue seat material as well. Front grille lower metal section. There may well be some other bits I've forgotten about. If anything interests you let me know. Collection/postage can be arranged under separate arrangements/costs.
Don't forget to get a new carb base gasket. Before you get the rebuild kit, unless you definately need to, it might pay to fit the carb and see how it runs first.
We have two Mk3 Golf's now. One was my upgrade from a Mk2. First one is the wife's 1.8 Auto Estate with around 78K from new. Registered in 1999 and very basic spec. Does what it says on the tin. Second is my 1.4 with around 143K. Had been in a garage for three years and is in excellent condition. Both have had servicing and minor niggles sorted out along with all new front suspension on both. Both are great cars. Pull the wheel arch plastics on the front and clean out all the much at the back of the wing. Ours were both in good contrition with no rot. So we've just added a 1.3 Mk2 Golf to the fleet. Time to get stuck in.... again.
