Hi, I have some probs with my w250. One of the owner before me removes some parts of the vacuum-system and change a lot of the electric. The TBI is still there but on petrol it runs very bad. The Truck runs on petrol and LPG.
I would order a Haynes or Chilton but it takes up to four weeks to send it to Germany, also with amazon.
It would be great if somebody can help me with a diagram of the vacuum/fuel system and a diagram of the electric?

Thanks Markus

Hey,
With the truck being a dual-fuel (petrol and lpg), it might be way more beneficial to take it to someone who know's what they're doing.

even the smallest leak with the lpg can cause very severe damages to property and potential loss of life

With that said,
I've never seen any hard documentation for a petrol and lpg engine. If you do find something, please post it here as I've been a bit interested in converting my truck like that.

 

GREAT..thanks a lot for the infos!

You ´re right...to work at LPG sytems can be dangerous
and maybe the last thing you do in your live if have no experience
with those systems;-) Actually my 2 LPG-tanks are empty....
I just have to check some electric wiring in the cabin
and some parts of the vaccum-system of the trottle-body.
