16 gallon tank swap question

I have 16 gallon one in my CMC (haven't had to refill for years - but that's another long story).  No alterations required (not even to hood lid).  I did loose space to store the temp size spare tire.

 

I doubt VS has changed their trunk body style at all over the years so following still applies:

I got mine from CIP1 but they no longer carry 16 gallon ones - only 12.5 gallons now.  I checked other VW parts places and same story.  I don't have actual measurement or capacity confirmation (so can't confirm the 16 gallons) but here's photos of mine installed in CMC. If you infrequently use car - I'd question keeping 16 gallons of alcohol infused ethanol in car for long periods of time (at least without Sta-bil).

 

 

Not sure the need for a larger tank in these cars.   I can get about 200 miles out of a "Full" tank and that is more than enough.  By then I have to get out and move around, gassing up allows for that.  I know for running around town, 8 gallons seens a little short, but still, no big deal.

 

Best of luck on the mod.

I also have a 16 gallon tank in my IM and haven't filled it in over a year and a half.

2x what Stephen said.  My tank  is 8 gal. I plan 25 MPG so I can go 200 miles until empty so I plan 175 miles which takes 2:18 at 75 or 2:30 at 70.  In a Speedster that's enough and by then I am ready for a short break for gas or rest stop.

 

12 gal would give 300 miles or 4 hr at 75. Four hours in a Speedster---really?  Not for me and I'll stick with my 8 gal tank.  Plus I can get a donut spare tire in the trunk.

Agreed.  2.5 hours is just perfect and I have a full size spare on  board :-)

Larger tank provides extra 70# weight in front over wheels that do 80% of braking.  It let's you fill up at distant non-ethanol pump.  Plus you have extra gas in case of an Apocalypse.  With fluctuating gas prices (low now), it's $ in the tank (bank?)  The 12.5 gal is about right where 16 is too big and 8 too small.

I did put (2) 25# bags of lead shot, one on each side of the battery for up front weight.  Fully did the trick. 

 

Gas is 6 lbs per gallon, so going from an 8 to 16 gallon tank is an extra 48 lbs. 8 to 12 or 12 to 16 is an extra 24 lbs. You normally use a half-full tank as the average weight.

That is what I like about the Lead Shot.....  50lbs is always 50lbs.

Really.

On the first day of math class I'd always ask my students which was heavier, one ton of feathers or one ton of lead. 

Guess which one most students picked....
