VOR Pump

[partsrowe]

2001 Johnson 40 that VOR pump was capped off and went back to mixing oil. Years after running fine I was having an issue of the engine not picking up RPM's when accelerating. Then had the carbs rebuilt, all new filters, ball and rubber lines replaced. Ran fine on first outing then the same issue returned. Pulled carbs and found rubber in the lower bowl. My mechanic is sure the VOR is desecrating since the rubber came through after the in-line filter.

Question, does that sound right? I hear that there is a fuel pump only replacement for the VOR. What is the best replacement for the VOR?

Thanks for your help...

Find a pump for a 48 HP model like your motor.----Marketed for many years.----That pump mounts directly to the side of the top cylinder over the pulse port.----Hoses need to be re-arranged.---Remove pulse limiter and plug that hole.

you don't have a pic of the rubber piece do you? It is easy to dismantle the VRO to see if in fact it is disintegrating.

You can send the VRO to me and I'll dissect it for you.
