At one time the fuel regulater diaphragm was considered a non-serviceable part due to governmental EPA regulations. Now this has changed, OptiMax fuel regulator diaphragms are replaceable with Mercury supplied parts.

Due to the construction of the fuel rails specialized tools and testing equipment is required. We at Lakeland Marine have all the tools and technicians to repair your fuel rails. Use factory authorized dealers with a established storefront. We have serviced OptiMax engines from day one.

Authorized Dealers Only

We started rebuilding the OptiMax fuel rails do to the unavailability of just the regulator diaphragm. Now we are able to replace regulator diaphragms with OEM Mercury supplied parts.

Don't be taken by the recommended person that supposedly did this service. Out of necessity we came up with our own way of repairing OptiMax fuel rails with parts supplied by Mercury Marine.
