If you just pull pump out you run the risk of the pump pushrod/tappet falling into the crankcase. Proper procedure is to remove bolts and make sure pump isn't stuck but do not remove, then rotate crankshaft and watch pump, when the cam lobe raises the loose pump to its highest position the pump can be safely removed without fear of the pump tappet falling into crankcase.
"1. Disconnect the lines between the fuel transfer pump and the fuel filter. Plug the lines.
2. Disconnect both fuel supply tubes from the fuel transfer pump. Plug the tubes.
3. Remove the two mounting bolts that secure the fuel transfer pump to the base of the crankcase.
4. Rotate the engine by hand until the pump is pushed up approximately 1/2 inch. This places the cam lobe at the top. In this position, if the tappet falls out of the pump during removal, it will not enter the crankcase.
5. Remove the fuel transfer pump.
6. If required, retrieve the tappet from the fuel transfer pump bore located in the crankcase. Insert the tappet into the base of the fuel transfer pump."
Is it even possible to loose the tappet down the cam hole? Ive had some of these corroded in so tight the pump had to be broken off down in the hole . When the oring was removed the bottom of the housing and tappet came out easily . The seal on the tappet shaft holds the tappet in pretty good so it should never fall out.
Oh yea. Been there once. I bumped it on something lifting it up and it went right down the hole.I ended up pulling the pan which is not fun to say the least.I was told they always go to the bottom of the pan and in my case it did.But I don't know if I would believe "always".The last one I changed broke off too, but if that sucker goes down the hole it will definitly ruin your day.
