I changed the fuel filters on Nora. The port engine is a 4.270d as opposed to the starboard one is just a 4.270. Apparently both are marinesed combine harvester engines. 1960 and 1961.
The manual pump is different on this side. It’s a plastic cylinder than unscrews then acts as a piston. It took 170 pumps to bleed both filters from empty.
The filters even have little handles to pull out.
It took 10 minutes in total to change both filters, Bleed them and start the engine.
I did not replace the o rings.
