‘72 CST K5 Gen 5 Swap

Gen V swap of first gen K5
Are you putting Matt to work making metal parts?
 
Home grown
I’m thinking it’s some old brand of aftermarket tank from the 70’s. It’s got four two foot long carriage bolts that drop down through the bed through sleeves in the tank.
There are four female threaded sleeves that screw up from underneath to suspend the tank. Pretty cool setup.
 
This fuel tank is yuge!

Please post the measurements of that thing. I am in the process of building my tank from 304 stainless and would love to know more about that thing.
Currently I have the bottom part welded and it is 21X29.5x8.25. The top was going to be 21x26.5x6. I stopped because I am contemplating making the bottom less than 8.25 in case I ever do slam it on bags or something. I would hate to have the tank hitting the ground.

It's aftermarket, I can't remember who had it in their k5, @Greg72 Or @RyanB
 
Thanks soo much! I assume that it fit well.

EDIT>>>>>>>>>>>>>>>HOLY CRAP!! I just did the numbers and that thing is about 41.67gallons!!!! Assuming about 18mpg (conservative) , that is a 750 mile range:k5::burnout:!!!Dang!
Yeah, it’s probably mid to high 30’s because of the beveled corners though.
 
IMG_0230.jpegIMG_0229.jpegAny first gen guys know what the deal is with these three fuel line/vent hoses that go up in the body?
 
My Dad's '72 C10 had a loop of steel fuel line going up into the cab corner next to the back window. Hoses connected it to the tank and a line going to the charcoal canister. ( I am fairly certain that I remember this correctly, but..)
However I can't explain 3 lines.
The truck did have a return line from the fuel pump that went directly to the tank.
 
That makes sense, and what I was thinking. Just hadn’t actually traced out the lines all the way. Thank you!
