Our 1987 Evinrude 70 (on a 1980 Striper 15) finally had a failure of the VRO pump. Unlike the stories about toasting a powerhead from low oil, the pump failed as is apparently common, on the gas pumping side, leaking gas. I found it when priming before a start - I'd suspected it was going bad since it appeared to be overpumping oil. No engine damage. This has been a great engine, with almost zero repairs to date. Between the lack of need of repairs to date, being 25 miles from a nearby dealer, and a minimum 3 week wait time for a dealer to replace the pump, I decided to replace it myself.

So, I got a new VRO2 pump from a vendor on Ebay and am ready to replace it, which is straightforward with good instructions in the Evinrude parts box. My main question is whether or not I need to replace the fuel, oil, and fuel/oil mix lines inside the engine cover. I've read on these pages about people replacing their fuel lines, but as far as I can tell the lines are in good shape and still flexible. Replacing the downstream fuel/oil mix line routing to the three carbs and primer would probably double my replacement labor time, and since the lines appear flexible I'm not inclined to do so. While the motor is 17 years old, I've had cars longer than that with original fuel lines, and the fuel lines on the outboard are protected from UV by the cover, like they would be on a car.

Lastly, there are 4 separate but similar lines with the VRO pump - gas in, oil in, engine pulse in, and gas/oil out. Is an A1 gas line in the appropriate size suitable for all of these lines?

Thanks for your feedback.

I just realized I posted this in the wrong forum. Please ignore this post and I'll repost in Repairs.

Thanks.
