VW Bus Engine Swap to AUDI 5E

Fuel Distributor and Aircleaner

This is the assembled fuel distributor from the front view. The brown pipe you see on top is a part of a 125mm sewage system, a special set to connect two 125 mm pipes together. I used only a half of it. The size fits exactly the outlet of the air mass measuring set. The white or silver aluminium is a part of the fuel distributor support. The black box below is the aircleaner box. There is a small hole below the distributor support. Onto this goes the combustion chamber ventilation pipe. The grey knee-pipe below is the air intake. It has to go straight to the left of the van because the engine support is exactly in front of this pipe.

This is the right view of the fuel distributor assembly. This is optimal for seeing the mounted pipes. The brown 125mm pipe connecting set is closed by a 125mm lid. Into this lid I drilled a 70mm hole, in which I glued a 67-degree 70mm pipe. The straight 70mm grey pipe going to the throttle box is not horizontal but goes a little bit upwards. This gives a better fit into the engine's compartment. The straight grey pipe goes into a special pipe adaptor which is regularly found at the aircleaner input. On one side it has a 70mm outside diameter, on the other side it's retangular. This fits the rubber part of the airintake. This rubber aitintake hits the left wall and the top roof of the engine's compartment. Down below you see the 87 degree 70mm knee pipe for the air cleaner intake. On the left end, not visable, is a 70mm to 50mm adaptor and a rubber seal for 50mm pipes which fit the size of the box air intake hole. The regular air intake for this box is on the left midsection and is closed. This is easier to see on another picture.

This is the fuel distributor assembly seen from the back side. Not very new material to see, but note the design of the srew assembly for mounting the whole set onto the body.

This is the left view of the fuel distributor assembly. You can see the mountings for the fuel distributor support. The low horizontal edge fits the low edge of the Vanagon frame rail. I used only three screws to mount the whole assembly. The upper left, the right one of the lower edge and, not very visable on this picture, the screw of the back end in the right side of this picture.

The bottom right view of the fuel distributor assembly to show the closed regular air intake for the air cleaner. Here you normaly find the adaptor I adapt the 70mm pipe to the rubber airintake to the throttle box. There are two versions of this adaptor available: a straight and a 90 degree version. Only the straight adaptor is useful. I had to cut the assembly which connects to this adaptor because the alternator needs this space. It's very close to the aircleaner box. The open hole I closed with some plastic, which I sealed with silicone. Also you see the 70mm to 50mm reduction for the air intake.

This is the top view of the fuel distributor assembly and shows you the design of the fuel distributor support. Right side is front, left side rear. The air cleanerbox is inline with the driving direction while the distributor itself is out of this direction. This is caused by the design of the air cleaner box.

This is the top view of the fuel distributor assembly, where the pipe to the throttle box is disconnected. This shows you the end cap of the 125mm sewage system and the 70mm pipe glued onto it. The 125mm connection set, which sits on the air mass measuring set, needs no extra sealing. It sits very tight onto the metal; you can not get it off without braking it.
