trying to test fuel pump on 89 rude 70 hp with the vro unhooked ,okay, unhooked top line going to carbs and connected a clear hose to top connecter and did not receive any fuel not even a dribble, i cranked it and let it run for bout 3-5 min and did not see so much as a dribble from outlet to carb, only thing is when i pulled apart fuel pump i could not see any visible damage , i guess its just bad, Should i have seen fuel pumping as soon as motor was running ? like i said i let it run for 3 min or so and i never saw anything but anyway any help is greatly appreciated!

Do you still have the VRO on it with oil side disconnected or a whole different fuel pump ?

Get a manual. That engine will not run 3 minute's without a fuel pump.

Get an OEM manual. From what you discribed it sound as the VRO has totally quit. One quick question, is the pulse line from the the vro to the crank case still hooked up and is it not broken or leaking?
