I am replacing my tank, found a cheap used/new one.
My old one, was emissions but nothing was hooked up.
The new one is non-emission but I didn't think it would be an issue.
Well I missed the part about the filler/vent hose orientation.
The tank holes are flipped to each other.
example
O o =new tank
o O = old tank
No biggy I think, I'll just get a bigger vent hose and cross it over the filler hose and clamp it down.
Now I wonder if this is even possible without having venting issues.
Has anyone done this successfully or did you just replace the filler neck hardware to match?

 

I haven't done this, but I don't see why you'd have venting issues as long as no hoses are kinked.

 

I agree seems like a silly question but it would suck to have to take it apart because gas keeps puking out at me.

 

A friend with a 78 got a 79 tank. Put a 79 filler neck on it. I've got a 78 tank (new, cheap)to put in my 79 so I'll use a 78 filler neck, and hole saw a hole for the emissions vent.

 

Yea I probably would have tried to grab up everything when I picked the tank up if I paid attention to the hose orientation.
I'll look for a filler neck, hope it's cheaper than the hose.
