4D61 fuel pump

[Vic K]

Anyone have a source for a rebuild kit for a 4D61 mechanical fuel pump . Anyone convert to 12 volt pump and bypass the mechanical?

Hi I have the same dilema. I talked to the Lehman expert in VIrgina very knowledgable and helpful. They are using electric fuel pumps you should give him a call. I forgot the details. I can find his number if you want. If I had a broken on I'd take it up lancaster PA to the Amish and see what they could do.

Thanks I would like the information. I'm not sure what the Amish can do for a broken fuel pump.

*Once upon a time* there was an 'official' electric pump conversion kit for the 4D61 - The info on the kit was in my ships papers when I bought my boat in 2003 which were sadly lost to Katrina. The kit was expensive as I recall (~$200) and came with the block off plate and gasket to replace the mechanical pump on the engine, a huge electric pump and a fuel filter. The kit was installed on my boat when I bought it . . . . there was no mechanical pump on the engine

I still have the electric pump which I'm not using because I have no idea where to find a replacement should it fail. If I recall correctly, you need a pump capable of 4 to 8 psi. I'm using this pump - They're cheap, so I bought two and will keep one aboard as a spare

I researched the forum here and can't find any reference to the kit which was installed on my boat, but it was a complete 'kit' and came with installation instructions and the block-off plate for the engine. It would be easy enough to use the baseplate of your old mechanical pump as a template to make a block-off plate from 1/4 inch aluminum and a gasket to seal the location on the engine when the mechanical pump is removed

Thanks for the information will have to get a few of those. The Amish in lancaster pa have great machine shops. The can do attitude is great have to go up there in a few weeks will see what they say. It's just a diiefram that goes bad. I just don't see what's so complicated about it. Always up set me when I need to buy a lift pump and it was so expensive and simple. But I was always in a rush and needed it quick so I payed

I had a fuel leak in the original fuel pump that was visibly contaminating the local waters through the bilge pump especially if I forgot to close the fuel line valve when in a slip in a marina. I could not find a replacement peugeot part for the 1984 engine in London or Paris so I replaced the original peugeot mechanical fuel pump with a 12v electric. Behind the original is an access port where a protrusion from the pump was activated at each rotation of the engine. I had an cover plate made out of 3/8 inch aluminum with a recess of about half the thickness of the plate to avoid touching any part of the engine that may have protruded to activate the original pump. That recess actually was over kill. I had two mounting holes for the cover plate drilled to match the original pump mounting holes and made a gasket from an available piece of rubber that would not be affected by oil or diesel fuel. I found an unused pre-drilled and tapped hole in the block as close to the original pump location to mount the new pump and used the original fuel hoses. The new pump is wired so it is activated by the ignition key which simplifies the bleeding procedure whenever needed. The new pump, at least for this engines has to operate at 8 psi or less. So far I am very pleased with the operation.
