leaking fuel ?

Featured Posts

hi all,we just got back from a weekend away and while sorting out the stern tube greaser i noticed a puddle of oil under the engine  BMC 1800 so i checked the oil level when the engine cooled down and there was no drop in level,so that left water or diesel,i dipped my finger in to find it was diesel,i then ran  my hand under the fuel pump and it came back with diesel on it,so my question is, is there something or somewhere i should check first ? many thanks in advance

make sure the bleed screws have not loosened. That includes the one and one of the injector pipe banjo bolts if you have one. If all tight and dry then its clean and dry off the pump, run engine, and look for dampmpatches. Some say dust it with talc to help show the damp.

lift pump or injector pump ?

the lift pump has a drain hole underneath it (almost impossible to see in situ) diesel from here is possibly the diaphragm leaking, it also has a rubber washer under the cap.

if the pump body  has fuel running down,check  the throttle spindle  first..............if you have a reversable governor,or a mechanical governor,the o ring seals can be replaced  for a few cents.
