OK I have a 1988 225 vro the fuel pump is getting weak on it. I premix my gas so I don't need the oilig side of the pump. Can I put the old style pump on there instead of that expensive vro pump????

The VRO pump is easy to take apart for inspection and repair.-----Some would disagree on that fact.----So take it apart first before spending any $$ on a fix.

Yes you can put on the dual pump setup from the earlier version of the (closest match) engine.

About half the cost of a new VRO pump.

You'll have the right mounting points but will have to locate the second vacuum impulse connection.

Its also possible to just disconnect the oil lines and the oil flow alarm wires. Plug the oil lines and it works as just a fuel pump.

At the age of your original (if its the original) the pump case parts should be inspected for cracking. It may be ready to fall apart.

Options:
A - rebuild factory VRO system. Run separate oil and separate gas tanks.
B - replace factory VRO with 2 x vacuum pumps. re: See Part number 8402-2 + 8402-60 within http://www.maxrules.com/fixomcvro.html Then, use 50:1 premix.

For option A or B, contact folks at Maxrules @ http://www.maxrules.com/fixelink.html

For my OMC 115, I disconnected factory VRO pump and use 50:1 mix. Mixing isn't a big deal. Will soon replace VRO with 1 x 0438559. For your 225 engine, you'll need 2 x 0438559 pumps -> which is near the same cost of rebuilding factory VRO system. Your call...

Hope this helps.
