    Lucas injection pump loses fuel

    Thank You for the reply! I want to buy a Bosch pump if Filipe has one (turbo UMM). I only have to get the UMM to the workshop without losing too much fuel on the street, that's the problem. I learned today that the piece is a magnetic valve. I turned it carefully somewhat to the right. best...

    Lucas injection pump loses fuel

    Hello friends, I have a big problem and I need advice: The injection pump of my UMM (Lucas pump) loses fuel at the tin / socket You see on the photos. The socket is on the side of the pump and it can be turned with two fingers...so it is loose. I want to change to a bosch pump soon, but...

    injection pump has a leak

    Thank You for the advice! I bought a seal repair kit for the pump at "injectionpumps.co.uk" today!. They have an ebay-shop. And I will also get a used part from Passarinho. I don't have time at the moment to demount and seal the whole pump as I need the car urgently for work in the mountains. I...

    injection pump has a leak

    Hello everybody, today I asked a specialist for injection pumps in Berlin about the Roto-Pump. He said that there is a membrane in the tin with the yellow cap and he said that this membrane is damaged in many old Roto-pumps and that this is probably the reason why the tin is leaking fuel...

    injection pump has a leak

    Well, I think that it is a Roto - pump (D.P.C). It is a pump with a two-point fixation. But the car is in a garage in the North Black Forest for the technical check at the moment , so I can't check details.....

    My UMM at Germany / Schwarzwald

    Hallo Paulo, the car was ordered by the french electricity service (EDF) in 1990 as a service car and built by UMM with the extended roof. It was blue and the car has a glass fibre plastic roof. so the roof carrier is somehow also important to protect the roof. I got the original order documents...

    injection pump has a leak

    Dear all, I have a problem with the injection pump: When I got the white UMM in 2018 it had not the full power (maybe 82 or 85 hp). I used it anyway for two years but I couldn't pull my trailer for work. Now a mechanic found the reason for the insufficient power: the tube between suction tube...

Yesterday we brought the UMM to a workshop in the Black Forest where they restore Willys Jeeps and where I got the permission for my first UMM (atmo)in 2007.

    Power of engine?

    Hello João, thank You very much for the immediate reply!! O.k., so the engine has 110 hp, but do You perhaps know where I could get a document where the technical data of the XD3TE/P152B are listed? I cannot find such a document in Google. It could also be a copy of the registration certificate...

    Power of engine?

    Dear All! I bought the UMM of Nello di Giusto from France. Perhaps some of You know the car (from UMM meetings), it is an UMM which was built in 1990 for the french electricity service (EDF) with a cabine which is 40 cm higher and longer than the standard version. The UMM has a turbo engine and...

    Hi Luis, thank you very much for the reply! Your wiring diagram will be a big help. In a neighbour village is a workshop where they can probably construct a new cable harness. Your cable diagram will help them. best wishes Mooro
