Born and raised here in good Ole lil abilene texas for 34 years now. I'm guessing ur from New Mexico then? That's cool tho, maybe after I get the pickup done u should come thru and check it out. I got a couple other projects going also. A 1982 elco and a 1964 4 door hardtop no post impala. Three pumps 10 switchs, u know just for fun lol.

K fellas that kinda brings everyone up to speed on my build. There r still a few things that I've already done but just haven't captioned any of it. Plus there's a few things I have questions on and hopefully some of yall professionals out there can help me out. But for the moment here's a few before and after pics side by side just to give an idea of how much hard work I've put into just the front end suspension. Once I'm completely thru I'll start on the engine and transmission work with new gaskets paint job and maybe a comp cam and some other goodies. I'll post the progress on that as well.

K guys so I'm needing some advice on the fuel lines I've already bolted to the frame. I had ask about a third line coming out of my fuel sending unit before I had taken everything apart and found out it was for a charcoal canister to help with the smell of gas. The fella told me that I really didn't need to put it back being that it was cap off with those caps u use on a carb, so basically it wasn't being used at all. Thats why I bolted only the supply, return, and rear brake lines, and decided to get a sending unit that only has two inlets. Well I went back to that thread and read some things about the smell could get really bad. Is this true? I do plan to get a vented gas cap but I'm not sure if that'll help. I really would hate to have to take back off my lines to add the third one but if that's what I have to do then so be it. Thanks for all the replies

It's not "really bad sometimes". To give you my honest opinion. Since the day I removed my canister, I have never ever had a gas smell or fuel odor. I removed the canister, put a cap on the steel lines at the left front corner of the frame where it stops on the cross member, I still have the steel line from front to fuel tank and I still have a 3 port sending unit with all 3 hoses hooked up. I have never had a single issue with smell, performance, reliability or anything. Then I swapped to EFI, still not a single problem and I have dual fuel tanks. That was at least 4 years ago. You should be just fine.

Awesome thanks for the info on that. U saved me a whole lot of time cause I was on the fence about the third line. Mine was cap off in the exact same spot and since I got it strip right now I figured right now would be the best time to eliminate the line completely. But I now have another question for u. How hard would it be to add another gas tank if it wasn't installed that way to begin with? I'm very Mechanically inclined and pretty sure I could do it with some do's and don't's. Anyways again thanks for the help, this site has been the most helpful site I've ever been on.

Your very welcome. It wouldn't be hard to add a second tank. Just have to get the proper parts. The parts are side dependent, so which ever side you currently have, you will obviously need the parts for opposite side.

Here's what you would need:
-fuel tank
-tank support brackets w/straps & hardware
-sending unit
-Crossmember fuel lines
-switching valve of some type and the associated switch/wiring, this would depend on preference and fuel system type. If you have EFI, then you will need a TBI valve. If it's carburated, you can use either a TBI or carburated valve. The TBI valve requires a little more wiring, the carb ones are a little simpler wiring. If it's carb you could also use a cable driven mechanical valve.

And if you already have the truck apart, bed off, open space around the frame, it's even easier. And believe it or not, with some careful hunting you could probably find everything you need in good shape from a wrecking yard or pull-a-part yard for much less than all new parts. Then some cleaning and they probably be good as new.

Well sounds like I'm heading out to salvage yard this weekend! Really doesn't seem hard at all also, I think the hardest part is going to be finding one here at our yards being that a lot of the older ones had been smashed. Right now I'm in the middle of rebuilding my steering box, all new seals only cause the bearings don't look bad at all I'll have pics of that also.
