Having found a leak at the fuel pump yesterday on my 1975 W116 450SEL. I replaced the siphon hose to accumulator and the 50 mm piece from the accumulator to the pump which seemed to be the culprits as they look to be original hoses and were badly perished with the siphon hose snapping when trying to remove it.
When I checked this morning yahoo no leak,started the car and oops leaking from the lower power terminal to the pump. The other hoses are recently replaced and dry. Is the pump cactus...
