I called LMC, the gentleman I talked to said nobody's ever called about the 1 3/8" fuel inlet before, so tomorrow I have to talk to customer service, find out if I got one that was put together wrong, or something along those lines. He didn't have any specs on what the in/out sizings were supposed to be, nor did he have info on what the tank was originally built for (ie. Blazer). He did say that I may be able to get my money back, but didn't say anything about an exchange if the tank is just wrong.
I found some 1 3/8" fuel filler tube, but one is a vendor-only page, I sent them an email asking where I might be able to buy this, the other was on Gates' homepage. No prices on that one, and I tried some of the auto parts supply places online catalogs, no go on the tube. I'm still searching, I'd kind of like to keep the fender filler, if I can get it plumbed up right.
Good luck with yours, Scott, and I hope yours works a little better than mine did. Sounds like you have access to a couple more tools that I do at the moment.
