4020 68 hood sheetmetal questions

1) Is there a tool to roll that sheetmetal edge for the muffler?

2) Is the rubber connector hose typical on the fuel tank or did someone cut the fuel neck and add hose so it was flexible to get to the hole?

3) I took off the sidescreens to see if someone had or if it was possible to rotate or move the air cleaner system to get the air in hole to line up with original hole on the hood. Not possible since the assembly is pinch strapped to the fuel tank. So wondering if there is some type of short offset pipe that fits in there.

If all else fails I am going to take the hood to a buddie and have him clean gut that fresh hole. And weld in a patch over old hole area. May be best to weld patch over entire area and cut new hole then do body work.

Another question is how the hood fits near the cab. I have a tab/ bracket on each side that has a hole in it. Cant remember what it is attached to...may be engine. Anyone know if the hood sits on top of these tabs or if there was at one time a secure system that went through the brackets/ tabs and into the hood? I have looked at every picture I could find and operators and IT manual to see how this is supposed to sit on there. The hood tucks under the cowl like it should now and I have a cab so everything stays snug. It appears that the sheetmetal on the hood where these tabs stick out is torn off..not sure as I was doing this under floodlight and flashlights.

Any help here is appreciated as usual.

My muffler hole is not too bad...just not a rolled edge. And the hood itself is now in place up against the instrument cowl. The radiator and fuel hole are ok. It is the airstack hole that was a factory hole originaly has been over cut to the nose of the hood. And the way it looks to me is that it had to be cut. The new hole was cut starting in the old hole but almost 2 inches towards the nose. And ther is no way to adjust my aircleaner to meet the hood hole. The radiator would interfere even if I could move everything back. Perplexing a bit.

The hose is standard "factory issue".

If you loosen the two bands retaining the fuel tank and air cleaner to the front support, quite a bit of repositioning is possible. I just replaced the fuel tank on a 3020 a couple of months ago, and went through that. I left the bands loose, then installed the hood, then aligned the fuel and air pipes with the holes in the hood before cinching down the band clamps around the tank.

My helper, Noah, before the front end and tank install.

The bands are a tad loose already I can tell that both have dropped a bit from their wear marks. I will give it a try but looks to me like the air cannister will hit radiator long before original hole lines up with air intake stack. Thanks for the pic. Looks like some work for a tank replace.
