Deleting VRO????

[weezzell_5400]

I have a fuel pump part #438559 ....and was wondering can I use the existing pulse limiter nipple to run this pump or should I plug that hole and put a nipple in the other pulse hole that's currently plugged ...I have a 1989 40hp evinrude and the vro oil side went out a few weeks ago and now the fuel side has quit on me as well...the pump that I have gotten from my local dealer was what they said I should get being that it's a bit cheaper than the vro rebuild kit ...and the fact that the motor and boat is new to me and not really knowing it's history of previous owner this was the route suggested to me ....also on the intake manifold there is a small brass nipple directly below the carbs ....am I correct in that the nipple goes to the air box as a overflow

There is a pump available that mounts directly to the side of the top cylinder with 2 screws and a gasket.---It is the best way to go.-----Plug the pulse port that was for the VRO.

I do understand that...but the pump that I have already chosen and paid for and have on hand is part #438559 and was just needing to know if the original vro pulse limiter nipple will work or do I need to block it and use the other hole ...and is the nipple below the carbs for the overflow from the air box....but thanks for the fast response ...love this site

Bombardier makes two types of old style pumps. They both work the same, but are designed to adapt to one of the two pulse line systems that were both used in the same time frame. Just depended on the engine. One of the old pumps is a two-line pump which then has to bolt to the side of the crankcase to receive the pulse. There is a single gasket involved. The other pump is a 3-line system. The pulse line on this pump connects to the single hose barb on the front of the block. They both work the same, as long as they have the correct rating. A number of my old engines are 3-legged pumps and the pulse line is the hose that goes to the nipple in the block. Take your pick.
