    Hey Guys...
    Just had a thought...I want a fuel cell, but like evrything else on my truck, I want to make it. I'm a good welder and have access to MIG/TIg and a plasma cutter as well as a whole host of other good metal work/fabrication tool.
    Anyway, was thinking of useing 12 gauge to 1/8 inch steel (mild). Anybody see any problems with this? I thought of the rust factor, but I think it will be ok. Shouldn't rust bad if I use an additive every other tank or so. I think. Any opinions? I would definatly leak test it and put a roll over vent in it, but any suggestions welcome, ok?
    Thanks guys,
    cS
    Oh yea...Any ideas on a fuel gauge sending unit? How bout safty measures?

    I have a 70' chevy 3/4 ton custom camper 2wd pickup. the saddle tanks under each side of the bed were junk. I made two new ones out of 1/8 304 stainless sheet. a 4 X 10 sheet cost me 225.00 about 5 yrs ago. then I bought Auto Meters universal sending units. I used the original tanks as a pattern to make the new tank from. the tank is one piece bent into shape and welded and the lid is a seperate piece. have to check fit the sending units fit before I weld the lid on permanante. there is baffeling welded inside the tank too.

    I measured the stock tanks sides and lengths, then I layed out the pattern on the sheet of SS. I marked the lines to be bent with dotted line and wrote the bend direction on the line so as not to forged which way it needed to be bent. then I used a plasma cutter and cut 1 in cuts on the dotted line leaving an inch and cutting an inch. I made sure at corners I left an inch to be bent instead of welded.

    then by hand I bend the pannels into shape. I hammer and dollied the corners and seams to tighten the bends and gaps up tight and welded all the joints together. they came out bitchen. I dont have pics but I can take some if you want to see them. they are a crazy shape.

    Ok here's my plan.....
    either 12 ga or 1/8 steel, rectangle shaped, but the floor will be at a dual angle, meaning it will go down hill by ways from the center. 1 of the pickupswill be the right side front corner, the other left side rear corner. Underneath the fuel lines will tie in together with a y. There will also be baffles on both ends to keep the pick up areas submerged at all times.
    Still haven't quite figured out how I'm gonna get a sending unit or filler neck in there yet, still working on that. What do ya think?

    so the floor is going to be high in the center then go down hill to the side walls like a upside down "V" except at a much shallower angle correct? then your going to "Y" the fuel pickup so it sucks from two points of pick up? thats how I understand it. what if one scaveging, sucking air while the other is getting gas, think that will pose a problem with how the motor runs? sounds possible just not sure how thar will effect fuel delivery to the motor.

    I don't think it will. My truck is still carbed, with the mechanical fuel pump, so I really don't think it's gonna hurt anythin. I guess I figure that as long as one sump is completly covered with gas, I should be alright. Crossing fingers anyway...
    I'm gonna take pictures and all that crap and maybe that will be enough coaxing to become a paying member so I can post all the pics up and everything.
    The only "real" drawback is that if I do this fuel cell, it will make it completly impossible to ever narrow the ass end of my truck, cause I plan on mounting it behind the rear seat, with a fancy home made metal "tonneau cove" thing I made so I would have lockable storage for all my tools and spare parts I carry in the truck. Now I'm gonna have to come up with a way to store that stuff too. Does it ever really stop? Or even wind down for that matter?
