New tank design now available they will come with a 90 degree fitment for your fuel attachment, and optional pump fitting attachment welded to bottom of tank.

Each tank holds 11.5 litre's +

You now premix oil in tank

These are a direct swap for old tank on

PX models fitted with oil tank.

Available in two types for P range

with holes for sender unit, or without.

These tanks have been exported around the globe to America, Europe they have been used for many reason's e.g. kitted scoots, cannonball run and general rally use to give that extra mileage capacity, so you don't have to worry so much about running out of fuel.

Each tank is sprayed roughly externally, and now pressure tested for leaks.

The tanks come with vacuum fuel pump, any other bit's needed you transfer from old tank.

TanVTank supplied with vacuum pump unless otherwise stated.

Vacuum pump instructions:

If you are using a vacuum pump you could either take it off the carb manifold or the engine casing as in pictures below these will have to be modified by drilling then tapping and inserting a bleed nipple or similar device to use as take off for vacuum pipe you must insure a leak free fit.

 Replace all other parts from old tank (fuel sender unit) and place in new tank after removing sender arm and replacing with new modified longer one.

The tank supplied is possibly fitted with a pump fixed to the base of the unit, this is an optional placement, move pump if not suitable to your needs.

Option 1                                   or            Option2

If you have been given an attachment for the vacuum take-off the tap size is 1/8 NPT

Important news we have just discovered an easy way if you find your pump is over fueling your scoot, if you insert a main jet into the vacuum take off pipe, (on the scoot we used a size 100 from an ordinary Delorto carb)  this will reduce the vacuum flow therefore stops over fueling, but the pump still works you will have to try different jet sizes to get your optimum fueling needs.

(with this, the scoot didn't need a feed return)

    We inserted ours into the end of the pump loctite it in to make sure it doesn't vibrate down the pipe.

Hope this helps any over fueling problems.

Electric pump fitting instructions  Not supplied

The fuel pumps characteristic is it uses a small power requirement, only 1.8 A with 12V DC voltage.  Brass tooth gear wheels are used for longer working reliability.

  When placing the pump and fittings it should be placed at the deepest point in fuel system.

 It should be arranged that the tube connections are tight. So it guarantees that the pump takes in no airs bubbles, and fuel immediately arrives at the carburetor. In Vespa PX models, the ideal place for the pump is shown in image 1, under the tank in the frame.  Since the electric pump can achieve 1.8 L/min, an overflow must be formed around pump, as in image 2.  For this purpose, you will need 2 T-pieces.  A "reducer" in the fuel line is sometimes necessary. 

 The pump supply can be reduced by adding a reducer a piece of pipe smaller in diameter into the flow, but the overflow however remains essential.  The motor of the pump is operated with 12 V DC Voltage.  In Vespa PX models connect the + to the white cable of the flasher relay, - to any point of the frame.  With Lusso models, green black cable leads both at the rectifier can be customized, + and -.  Swapping round both cables can change the route of direction the pump flows.
