Re: Vro
Older model VRO pumps are bad about going out. Might want to convert to mixing oil yourself. Just remove the old combo Fuel/VRO pump. Plug the lines, then install the old style fuel pump. Be sure to mix your gas/oil 50:1.
I just did one. Not too difficult. Results might shock you. Mine runs better without the vro. Might also want to put in a water/fuel seperator type filter and remove the one in the engine compartment. Lots less hassle, and easy to do while your working on the fuel system anyway.
