Hello together, my Manta B GSI, BJ 7/86, was shut down for 13 years and now I am in the process of activating it. I had to replace all fuel lines. At the front everything was easy, at the back it is a bit more complicated at the moment from the procurement side. Since I am a learned screwdriver, I hope from my post here maybe a few tips. In the back I have the with, and dismantled. The hoses fell apart – are now also 30 years old. I could also buy and replace most hoses without problems. Alone a very thick (a short piece of this hose was also ) was for me with no car parts dealer (Blöcker, Schneider, Büge, Matthies …) to find. My next attempt is the one with the local Opel dealer – maybe the area spare parts (for old-opel?) can help me. On the other was a second petrol hose, which had a relatively thick, but only an inner diameter of approx. 7.5 mm. A uch this one was quite rotten below the floor plate, so I want to exchange it. But that also does not seem to me to be a “normal” petrol hose. Since I did not know until a few days ago which parts are installed below the tank, I would be happy about explanations about the components , and . My thin knowledge is based on Internet research. Who can explain these parts and the function to me a little bit more? I have packed four photos in the attachment. 1. The dirt of the years 2. De r coarsest dirt must be lowered 3. The two hoses to the tank 4. Extensive carrier with old components 5. Extensive carrier with partly new components A nice weekend!
