Fuel Pump

To remove the fuel pump, located next to the distributor  removeand plug the two lines that come from the fuel pump.  One goes directly to the gas tank, so have a golf-tee handy to plug that one up.  There are the two nuts that hold that down (13mm) and pull the pump straight off.   Put all of this into a  bag labeled “Fuel Pump”.



There should be a gasket, a rod, and a plastic rod-holder, and another gasket under all of that.  Take the rod out carefully and make sure to keep it clean and bend-free.


If your lucky, the plastic piece will just come out, if not, tap lightly with hammer until freed.  Note, this could break the plastic, which you should replace anyway.



Also not the difference between the two gaskets and keep this in mind for re-installation.  Put all of this into your “Fuel Pump” bag.


This is a three piece exhaust system with a muffler unit and two heat exchangers on either side of the engine.  Before starting, remove the two large paper hoses that attached to the fan housing. Remove the muffler from the heat exchangers by removing the “rings” that attach these together.  Each ring will have a nut and bolt on each side, gaskets, and seats over a flange in the exhaust.   There are four of these, and pending the age of your engine, could be very rusty.  I recommend buying new ones.  There is also a wide band clamp that needs to be removed from the heat exchanger, shown below.  Also, remove the remaining four nuts that hold the muffler onto the head.


Moving on, grab the pea shooters (at the end of the exhaust) and pull the muffler off.  You will now direct your attention to the heat exchangers.  Roll the engine over on it’s stand and remove the two arms of the exchanger from the tin.  There will be gaskets between the connections between the muffler to head and exchanger to head.


Once this is done, remove the nuts that hold the exchanger onto the head.  There will be rust, so use plenty of rust penetrator.  Once done, the exchangers should be freed from the engine.


Put all of this into a bag labeled “Exhaust”, minus the muffler and exchangers of course.

Now onto part four…
