does any one know of a injection pump that does not need fuel or use fuel for lubrication of it's moving parts that would work on a 1.6N/A VW?Thanks for all your help. :?:

There is no bolt on injection alternate system for the VW diesel. Bosch makes some ceramic plunger pumps for use with water emulsion and alcohol fuels. These are designed for large stationary engines though and are about the size of a VW engine.

The inline pumps used on larger engines and the mercedes diesels depend on fuel lubrication to a lesser degree but still cannot handle fuels with little/no lubricity. These pumps are also huge and will not directly bolt up to a VW engine. Any inline pump fitment would require adaptors for the mount as well as the shaft and custom bent injection lines. You may also need a bulge in the hood to fit it in.

What is the goal of the pump swap?

Juat had some alternative fuel ideas that might not have oil in them or very little at all.If you could help me on where to start my search to find such a pump would be grate.Thanks for the help

The dual fuel army trucks use some sort of pump that evidently doesn't require lubrication. I don't have first hand experience with these, but from what I hear, they can burn just about anything combustible, although they run better on some than others. They also guzzle fuel (being a 15,000 lb truck...)

i have that engine in my m35 and it gets 9-10 mpg for a 13,030 lbs truck. compare that to any 1 ton diesel truck. dont forget i can haul 10,000lbs. and it will run on any slop you put in it . the I.P. looks like a regular rotary I.P.

Hmmm, I have that sticker in my Mercedes turbodiesel. In fact, I have used jet-a in it before.

A good story told to me by an army friend about the 1970's Chieftain tanks on an excercise. The injection pumps on these things were designed at great expense to be multifuel. So they were running on petrol instead of the usual diesel. It was only very shortly later once there were a hundred 60 ton paperweights littered all over the West German countryside with siezed injectors , that the penny dropped that somebody had ballsed up, and the injectors had not been included in the redesign process. The need of each tank to go into the field with a hundred cans of engine oil to add lubricity to the fuel would have been an admission of a cock up, so diesel only ever after for these beasts. This is a friend of a friend story, so your mileage may vary.

But the point is you may need to source some uber exotic injectors.

Someone has got one running, it's a Leyland L60, sounds good and angry when revved.

Don't know if it would solve your problem, but the Simms inline pump on my Ford Super Dexta has it's own oil resovoir. May still need the lubricating fuel for the pistons though.

I think I have the service manual for that engine... turbo? Inline six? Came out of the Sixties?
