FYI. I asked the same question REF: manual primers. If you were to use the manual primers because the electric fuel pump was inop. you would be ILLEGALLY flying. Because if you did take-off and had an mechanical fuel pump go out then there is a complicated procedure to cross-feed the inop. engine fuel pump. See the other Skymaster web site
www.skymasterus.com for detailed explanation.
