Thanks guys. When I got the blazer the tank it had looked home made, I assumed it was an attempt at a larger tank. Was horrible and went to the dump months ago, but I did save the hose, more are a template knowing it would need to be replaced.

Now I understand the missing part, although it looks like it bolts on, and the tank I purchased doesn't have any studs to bolt anything to. Looks like I need to source a filler neck, or make something somehow
