We have assembled two kits based on the Webasto Air Top 2000 STC heater kit 5012558B.

We take that Webasto USA kit and add 3 kits to it. The object is to make the Webasto installation as DIY friendly as possible by eliminating fuel tank drilling. Then we add all of the available silencers to your heater to give the quietest operation possible. Not only is it nicer for humans, your dogs with sensitive ears might like it too!

We compile an easy to install Combustion air intake silencer kit 90-3-0005. This kit fits all heaters with 22mm air intake ports and includes 6 individual part numbers and 7 pieces. 100% genuine Webasto parts!

In addition we add our Combustion exhaust air silencer kit 90-3-0006. This kit fits heaters with 22mm exhaust ports and includes 6 individual part numbers and 10 pieces. 100% Genuine Webasto parts!

We add a fuel tank tap kit to use the factory port on your fuel tank - ELIMINATES DRILLING THE FUEL TANK. The Ford Transit Gasoline and Ram Promaster use different fittings and therefore each require a unique kit based on this 1 item.

Promaster - Sprinter fuel tank tap kit 10-7-0010 includes 4 individual part numbers and 6 pieces. 100% Genuine Webasto parts.

Ford Transit Gasoline fuel tank tap kit 10-7-0011 includes 4 individual part number and 6 pieces from 2 different vendors. Genuine Ford and Genuine Webasto parts used in this kit!
