I haven't yet had either fail on my '02 at 164k miles, but many have had HP pump failures. I recall 1 LP pump failure Search here and on the yahoo sprintervan forum for details of both. As I remember, the HP pump failure begins as a fuel leak from one of the 3 cylinder heads when cold (seals when hot) and eventually leaks all the time. I suppose the HP pump could wear internally and eventually fail to provide adequate pressure/flow, but I haven't heard of that type failure.Hi. Wondering if anyone has had to replace either the low or high pressure fuel pump on their 02-03 Sprinters (OM612 engine) yet?
Also, how many kms/miles did the pump last?
What are the signs to look for when the pump is failing?
