Hi Guys,

I've tried to mount my Vdo oilpressure sender on my type4 1800 - but it scrubs the side of the distributor.

Is there some kind of extender-tube-pipe-thing that will fit?

Thanks...

grease gun hose is the simplest, there are other kits out there too

I used the 42 draft design version. Very happy with the kit

The thread size is actually 10mm x 1.0. If you use a grease gun hose it will be 1/8 npt. It's very close to the same. Instead, use a stainless steel aft left hand 1968-1979 VW bus brake hose. This hose has a female on one end and a male on the other in the correct thread size. The fact that it's stainless instead of rubber means that the hose will conduct to the engine case for the sender ground. Otherwise you'll need to run a special wire for that possibly.

Also, I talked with the guys at 42 Draft Designs about making one that would be long enough that I could mount the tee on the firewall, and they said that it would not be a problem. I like the idea of mounting the tee to something instead of leaving it dangling around.

Thanks guys.

Thought about having my friend who is a machinist to fabricate a metal pipe that lever the feeler above the distributor. But in order to be able to measure a correct oilpressure, how big an inner diameter should pipe have?

Thanks again.......

This is how I did it last. This time I will use the stainless hose though. I installed a rivnut in the engine tin to mount the clamp that holds the sender. Hard to see it but that's a metal clamp around the sender where the WK and G are labeled.

And for a really finished look, order up a set of these and put the 5th one on the oil pressure "hole with the extension hose". They fit better over the spark plug holes.

The Wildthing turned me on to them!

don't want to make an extender. You want to go like Gary did with the hose. We lost an engine at Willow Springs because a short extender tee snapped from stress cracks that started at the threads. I showed it to a well known racing engine and car builder who is a friend. He said, "seen it before. Everyone has been thru that one."

Use a good high quality hose made for hot oil and place the weight where it does not move around. Many of us do like Gary did.

Gotta get me those tie rod boots for the spark plugs Randy.

I too used the 42 draft designs unit and mounted it on the engine tin.

I didn't think they still made them. Tried to find it on their website but to no avail.

Nice, clean, business-like unit.

If anyone is in a large area with industrial stuff, this type of hose is easy stuff. While in the Los Angeles area, Comoso.com, can outfit unique situations without a strain. They are a Parker distributor also. Our oil systems are low pressure systems compared to other industrial applications.
I used a comoso hose assy to relocate a vdo sender on a type 1 engine years ago.
Hope this helps, Bill.

I posted the link in my post above.

On my bus, I still have the EGR pipe from the tin to valve installed and I mounted the 42DD and senders to that. No drilling or pressure on the either end of the hose

Just want to check and make sure - does the switch ground adequately through the clamp holding it to the tin?

run a ground wire to it. I soldered one to the sender case and ran it to ground.

When I submitted this article (which was based upon my own investigation of the then readily available new & second-hand parts that could potentially be used as installation adapters), I marked the photographic prints on the back to show which edge was at the top, and coloured the text for the picture titles and captions in RED & GREEN respectively. Sadly, the magazine layout designers appear to have COMPLETELY ignored my guidelines, so several pictures are incorrectly orientated and it’s more difficult to read and interpret the article than it should be!

At the time, I had not long since completed two supplementary part-time courses in desktop publishing and graphic design using Quark Xpress, Adobe Photoshop & Adobe Illustrator, so I knew what could reasonably be done! Fortunately, more recent issues of Volkswagen Camper & Commercial magazine (first published in Winter 2000) were much better laid out!
