So I got the tank situation all figured out tonight. I bought the stock sending unit that actually fits the smaller hole of the new tank (thanks Summit Racing for having the correct "stock" sending unit and getting it to me in one day with standard shipping). The other "stock" sending unit is going in the trash because I already ditched the box and receipt when I opened it the other day, and who knows what it belongs to. I washed the old tank out with dish soap and water, and allowed it to dry before deciding to make life interesting using a three foot long fuse of toilet paper to see what would happen in my back yard. Holy hell was it just like a jet engine when it lit after being all washed out! I have a video of me lighting it again later, and each time I go out it will reignite with a little less oomph. Dont mess around with old gas tanks, the residue will continue to reignite, and reignite over and over! I managed to get the filler neck chopped off without any burns, and decided to use fuel tank repair putty and sheet metal screws to attach it rather than welding. My lack of welding experience led me to believe I would pry end up with pinholes and be worse off than what I chose to do. Here are some pics of the old gal all done up.
Out with the old:
With the use of these friends I got it cut out, all the rust removed, and shaped to fit snug on the new tank:
And the end result. For those of you doubting this, the filler neck extends around two to three inches into the tank, and that putty is completely underneath all that excess metal up to the neck, not just around the edges. That thing isnt going anywhere.
@madmike1157 I had your old sig character rolling through my mind as tonights events unfolded. The only thing I didnt do was pour the gas on myself first.
Maybe I can accommodate you w/ a real version of that,..I'm gonna cut my own tank, make my own sump, and weld it.
I realize that there are uhh.....hazards when welding an old tank,...I'll typically wash it out several times,..and actually let it sit for several days to air out. I think the last tank I did actually had water in it while I was welding.:trip:
