While waiting for information about other areas of the project, decided to do the fuel pump overhaul. This turned out to be pretty simple, using a kit I had ordered, except that the kit included press-fit valves only (turns out that mine has screw-fit valves, which luckily were in excellent shape), and while the diaphram assemby went on without problem, the tabs on the new didn't match the tabs on the old, as if the flexible material had been installed upside down. Careful examination indicated no differences between sides, and it installed, as mentioned, without problem. Testing it manually showed it to be working normally.
This is how it looked fresh off the Rover. I'm guessing that no-one had really checked if there was sediment in the bowl in a while. The loosening knob at the bottom was seized, as well.
The screw-fit valves:
The aptly named sediment bowl: inside view.
The ensemble after disassembly and light cleaning. Sediment bowl took the most work, requiring a lot of scrubbing, but ended up looking like new.
The overhaul complete, with new diaphram, and gaskets (including the rubber one for the bowl) and ready to go back on. The sediment bowl clip had been soaked overnight in Evapo-Rust, and now the loosening knob works as it should.
