Fuel pump

This will be a bit of a short post this week and although it does not appear that much has been done but both removing the pump and refitting it have been fiddly time consuming jobs with regard to the amount of parts that had to be removed to gain access to the various fasteners on the pump. I started this week by remaking a couple of banjo connections on the secondary fuel filter, these had been weeping ever since I got the engine running but to reach them it was necessary to move the heat exchanger and as I had to do this to remove the exhaust manifold so that I could remove the fuel injection pump it was an ideal opportunity. Once the leaking joints had been repaired I gave the engine space bilge a good scrub down with the industrial strength detergent followed by a wash down with hot water the residue was then removed with the vacuum oil extractor.

I had a call on Tuesday afternoon to say that the fuel pump was ready for collection and so first thing on Wednesday morning saw me on the way to Rochester to collect it.

Refurbished fuel pump

I managed to get the pump in place and bolted up on Wednesday afternoon there is a master spline on the pump drive shaft which fits a corresponding spline in the drive gear it took a bit of fiddling about to get them to line up as once the pump is in position the spline in the drive gear cannot be seen however with a bit of trial and error it all of a sudden slipped into place.

I had a bit of a late start today but first thing I primed the low pressure side of the pump using the hand lever on the lift pump. I then went on to get the exhaust manifold back on together with the cooling water header tank and the oil filter, then connected the throttle and engine stop cables just leaving the replacement of the heat exchanger for next week. I expect that the idle speed will need adjustment as a new adjuster was fitted as part of the refurbishment that will be a job for next week when the tide is at a suitable time to run the engine, one of the disadvantages of a mud berth.
