Pulled the fuel tanks off today and started to rinse them out and clean them out.
I had the Right tank off and poured about 5-10 Lt of brown stale fuel out of it, also found the pick up was blocked and the sender frozen. So I have washed that tank out nearly 12 times with water and now have a fuel tank cleaner in it sitting overnight. Used wire to clean out the gunk in the pick up.
Pulled the left tank off and put a little water into it with the hose, tipped out a thick brown sludge. So that too has been washed/flushed about 12 times and is reasonably clean. It is drying out now.
I found a plastic 3Lt container and have rigged that up under the tray with a flexable rubber hose off the fuel line into the container, now filled with petrol.
Used the Jeep to wind the truck over to check all was ok and to get fuel up to the carby.
Got the fuel up but it would not start. Checked the obvious to see if/where I had spark. No spark.
Test light out and checked to see where I had power to.
I found that the main lead/king lead into the distributor was dirty/rusted in the cap, so a little emery paper and it was clean. Also good to pick a good clean earth point to check spark
Then the truck fired up, ran it for a few minutes on 12V.
Had to refill the radiator, pulled the 6V battery out of the Dodge and placed it into the Chev.
Started up and ran, so I took it for a drive around the yard, then placed it into the workshop with my dad and wife checking to see if it would clear the roller doors. While on the short drive the radiator leak turned into a gush and I was slightly covered in warm water.
I have 20mm clearance on the main door and 40mm clearance on the smaller door at the rear of the workshop.
At least it fits, so tonight it is parked up inside the workshop sleeping soundly with the rest of the herd.
Some pics attached.
