The mid-tunnel Wassell style peanut tank is the happy medium between our Frisco Wassell gas tank and our Deep Tunnel Wassell gas tank.  It’s like the Goldilocks of gas tanks:  not too high, not too deep, it sits just right.  This peanut tank also features our widest tunnel width so it will fit rubber mounted Sportster frames years 2004-2006.  Gas cap sold separately.


  • Mid-depth tunnel
  • Undrilled mounting tabs
  • Bungs for two 1/4" NPT petcocks


  • 2.1 gal capacity
  • 14.5" long x 9" wide x 7.5" tall
  • 17" tab to tab
  • 3.5" deep tunnel
  • 2.375" wide tunnel

Tanks are pressure tested at the factory, but it is best to test again before you paint it.  Be sure fit of tank, mounting hardware, petcocks and gas caps are true prior to painting.  No stress is applied to the tabs when bolting them to the frame, this can lead to cracking of welds.  If needed, use leather or rubber washes to shim between the tabs and the backbone to ensure an even fit.  Do not sand seams or welded edges of gas tanks, if needed use a thin spread of body filler prior to painting.  Throttle Addiction warranties gas tank defects however we do not cover paint work.  Ensure your tank arrived damage free BEFORE you paint!

    Killer bang for your buck

    This is a pretty good tank, it is nice to see more support for the Rubbermount Sportsters since the frame is beefier and shaped differently. It was a also a nice suprise to noticeably tell the difference in weight from the stock tank to this one. The welds aren't the cleanest but the metal work on making this tank smooth is pretty killer and saves loads of time with body work.

    Nice tank...

    Clean welds... pressure tested, no leaks... fat tunnel for hiding electrical... no cap included anymore, who cares... nice tank! Dual outs is a sweet option on a mid-tunnel / hopped up front end (suck on that second half!)... pretty sure this is a 1.8 gallon tank though, was a little bummed it didn't fill a gallon container twice (duals make up for it). This is the only version that has strictly dual outs (like an original), no ugly center bung messing up yer pretty side... the kicked out duals bungs are a bit different, but make it much easier to wrap your fuel lines back around and not drag on the rear head. Overall this is the best new wassel option out there, worth the extra $$!

    Great for holding fuel!

    I got this tank. My hairline stopped receding. I lost fourteen pounds, and had to make a special stick for beating women off my body. My carb seemed to tune itself, and I think it actually added a few horsepower, by the feel of things. Seriously, it's a nice tank. The dual outs is a nice feature. The cap is a cheap-o bayonet style, but this is a cap that comes with a tank for $159 - I mean, really, how much can you ask for? I would buy this thing again in a heartbeat.
