eaglescout526 Posted April 3, 2021 Share Posted April 3, 2021 I would like to just do a PSA since I couldnt find the internal difference anywhere via pics or word so I took it into my own hands to figure it out and I am glad I did lol. 16: 23.5: don't worry, I plan to clean it out before use. BUT! Note the shorter vent pipe. And only reason why I did this as the tank I bought a while back from a member in CA didnt have the tank ID plate on it so I had to find out and verify. External differences 23/16 tank: Dims: (from lip to lip) 37"L 17 1/2"W ~15H 18 tank: Dims: ? 16 and 23 side by side Link to comment Share on other sites More sharing options...
Pete M Posted April 3, 2021 Share Posted April 3, 2021 holy crap! can I get more gas into a 16 gall if I trim the vent tube? Link to comment Share on other sites More sharing options...

eaglescout526 Posted April 3, 2021 Author Share Posted April 3, 2021 Actually I don't have a good pic of the internal to an 18. But I will say its the exact same, but it fills more direct rather than the fill tube on the 16/23 being curved toward the slosh pan. Link to comment Share on other sites More sharing options...
Pete M Posted April 3, 2021 Share Posted April 3, 2021 how do they compare size wise? what are the dimensions? Link to comment Share on other sites More sharing options...
eaglescout526 Posted April 3, 2021 Author Share Posted April 3, 2021 The 16 gallon is definitely longer than the 18 gallon tank. But the 23 and 16 gallon are one in the same tank only with the fuel "baffle" being different to let less or more fuel in. Once the light returns tomorrow morn I will edit the main post with the pic of the 23 gallon. @Torq_Shep, not sure if you installed the tank yet but would you mind providing us the dimensions of this lovely tank I sold ya?

WahooSteeler Posted April 3, 2021 Share Posted April 3, 2021 If Eaglescout is willing to write one up, I'd like to recommend a sticky on this subject of fuel tank dimensions and FSU's for the 3 different sizes with accompanying pictures. Even though new tanks and now FSU's are available, this info IMO is one of the most common subjects that I've seen in the 10+yrs I've been on this site.

gogmorgo Posted April 3, 2021 Share Posted April 3, 2021 Interesting. My build sheet said mine came with the 23gallon tank, but it always seemed like I was forcing fuel into it to fill it all the way. Makes me wonder if it didn’t have a 16gal swapped in at some point. It was confusing to me given how hard it should be to plug up such a big vent tube. Unfortunately I can’t really investigate this because that tank was swapped out a few years ago after an incident with a deer, and the shop that did it tossed the old tank. I also haven’t been to a gas station with it yet due to it being mostly parked awaiting rust repairs to pass an inspection after an interprovincial move so I don’t know if anything changed.

eaglescout526 Posted April 3, 2021 Author Share Posted April 3, 2021 I’d be willing to do a write up on all the specs and what not of the gas tanks and FSU’s. Would be an invaluable thread with hopes that all those questions could be answered with one topic. Link to comment Share on other sites More sharing options...

ghetdjc320 Posted April 4, 2021 Share Posted April 4, 2021 So on my 91 swb I believe I have like a 16 or maybe 18 gallon tank. Is there an internal mod that would add fill-up capacity? Link to comment Share on other sites More sharing options...
eaglescout526 Posted April 4, 2021 Author Share Posted April 4, 2021 Short beds should only have the 18 gallon tank. If you got a long bed tank into a short bed, I would like to see that. I know some SWB guys would like to as well. Link to comment Share on other sites More sharing options...
Pete M Posted April 4, 2021 Share Posted April 4, 2021 if there's a way to shorten up the tube inside, then maybe? I don't remember hearing of anyone trying. Link to comment Share on other sites More sharing options...

Yeah I was looking up a video of the inside of my tank that I took when I cleaned it out and don’t see anything that would open up capacity. All well, the 18g tank works for me, always nice to not have to fill up as often especially at $4.75/gal Link to comment Share on other sites More sharing options...
