Can anyone tell me if it is possible to attain some type of repair kit for a VRO2 pump? We have a 1991 40hp Evinrude Model # TE40ELEIA. The previous owner had cut off the VRO system but was still using the fuel side of the pump. After much trial and error we realized we had air suction problems and narrowed it down to the diaphrams in the VRO which are deteriorated. So far, I am seeing that they don't manufacture a rebuild kit for this pump. Is there somewhere you can get those diaphrams? Also, wondering if there is a site somewhere with a diagram of the internal parts of the VRO. Appears this one may be missing an o-ring but not sure. Any help would be greatly appreciated!! Thank you!
