Modern Vespa

Note! I am not a mechanic and what I do / learn is by trial and error. I have received a significant amount of help / advice from Modern Vespa Forum Members and Staff.

I have used several auxiliary fuel tanks with my GT-200. Two have been temporarily mounted and one has been permanently mounted. The first two were 2.5 and a 6.0 Gallon respectfully. The permanent mount is a 2.25 Gallon Plastic "Tour Tank", originally sold as a "Wind Bag" prior to being re-named. It appeared like a "Bed Roll" when it was available in the plastic version but now is sold as an Aluminum Tank with two options to make it appear as a "Bed Role" or whatever. My original's canvas cover began to rot so I decided to take off the canvas cover and just re-mount the plastic tank. I do not have access to a Digital Camera all the time so the original install was undocumented. As a result I documented the "uninstall" of the original in hopes of properly identifying what I had previously done. In addition, I chose to replace the fuel line I installed originally. The fuel line I chose at that time became very brittle and I was concerned about having a leak as the result of its brittleness. The pictures I will include are just that, pictures. I'm still learning to make / modify them to better explain what I did.

Thanks for the photos, Mike. Can you tell us whether you feel a change in the handling with a full gas tank?

I have been using the Tank for about 18 months now. "I" do not notice a difference. The Tank holds +- 2.25 Gallons so the weight must be about +- 14 Pounds. I'm guessing at the weight.

When I did the original install, I drove with the Tank filled with water and not plumbed in to the system. I did this to insure that what I had rigged would support the weight while riding on rough finished road surfaces. It worked fine so I plumed it in and went to Gas Vs. Water.

As I understand it, Water weighs about one pound per pint and Gas, depending on the additives and octane, weighs about 6.26 pounds per Pint. At any rate, I figured that by using the water, I'd over stress the mountings to insure they would hold.

My apologies for the disorder of the photo's, I just didn't get them in the order I intended them to be. I also did not get the names / captions of my photo's to load - appear on them once I loaded them. Sorry!

Best regards,

Mike, I think you meant gasoline weighs about 6.26 pounds per gallon. You obviously know water weighs more from your comments, just wanted to point out the typo.

"A pint is a pound the world round..."

the world round has switched to metric. just a few hold outs.

I especially like the Greasy tool (The Corona BARELY in frame in one of the photo's!)

Hey, if your selling pints for a pound each, I'm buying

"... except with petroleum based products..."

Doesn't quite have the same ring to it... I don't think it will catch on.

Great job...thanx for the photos and details....

I notice in your photos that you had to remove the floorboard to do your install. What's the trick to doing this? I need to route some wires under the floorboard and I cannot seem to find all the screws that are holding it down.

I've removed the 3 screws on each side under the outside rubber strip. And the 4 screws on the batter cover. I also removed the larger screws on the battery hold-down. But there must be something else holding down the floorboard near the rear.

Thanks for any help you can provide!

I'll need to look in the morning when the Sun is up.

I do not remember exactly how many but in the morning I'll check it out.

Wow that extra tank is super cool!
