New Walbro pump and maintenance

Today was a  maintenance day on Aeolus and what a day for it. The weather in Anacortes was as beautiful as a day could be, with bright fall sun and temperatures around 65. Just perfect.

My trusty old Walbro 6805 which will be retired into backup status. 

The FRB13-2

My main project today was replacing my main fuel pump, which I did merely out of an abundance of caution. My trust Walbro 6805 had given 10 years of reliable service and about 1500 hours of use. This is far below the rated hours for this pump, but after 10 years, I just felt like it was time to replace it. Fuel issues are by the far the biggest cause of engine failure, and I've had recent experience with stormy conditions that reminded me of the desire to never have my engine fail.

I replace the 6805 older model with the newer FRB13-2. Interesting to note that the 6805 was rated only for diesel fuel, where the FRB13-2 is labeled for all fuels, including ethanol and all biodiesels. Since I run biodiesel, I'm happy about this, though I never did have trouble with my 6805.

The swap out is easy, and even the mounting hole patter is the same.

While down there I also replace my exchanger zinc. Ever since putting a spacer between the transmission and prop shaft I have had much less rapid corrosion of my exchanger zincs. It is now electrically isolated from the shaft, salt water and propeller. They last about a year for me now, and at that time they are only about half gone. A nice interval.
