Gas tank filler hose?
Swapped in an aftermarket '87 20-gal tank (with baffles) to replace my 20-gal carb'd tank and the old filler hose pipe is a smaller diameter than the inlet to the new tank. The hose pipe is prob. as old as the truck (1980) and is thus hard as a rock. Is that the reason why it doesn't fit, or did the '87 tanks come with a bigger inlet diameter, or is it because I'm running an aftermarket tank?
Need to know because I want to go ahead and order the part from LMC, but don't know if I should order for a 1980, 1987, or not at all?

Well the '87's were TBI, I imagine that has something to do with it. Totally different system.

Re: Gas tank filler hose?
Just did a swap of an 84 tank into my 77. My 77 has a inlet hole of 1 and 1/4 inches and the 84 is 1 and 5/8. I believe 82 and up were 1 and 5/8. Check ebay for 87 gas tank and usually they say what size the inlet necks

Re: Gas tank filler hose?
Thanks for that...for some reason I didn't think to check the diameters of the different tanks (I still have my old tank kicking around) with my calipers
