PA28/38 Fuel Strainer Drain Check
Concerning the preflight check of the fuel strainer drain and checking for water etc., nowhere in the Flight Manual/POH is any mention made of switching the electrical fuel pump ON for this check, although some pilots seem to feel this is necessary. Indeed the fuel pump is downstream of the fuel strainer so can anyone tell me how switching the electrical fuel pump on will enhance the flow of fuel from the fuel strainer?
Interestingly though the Flight Manual/POH does mention that this check should be made on both left AND right tanks.
Thanks for any help.
