I installed a new fuel line from the filter to the inj pump yesterday and was working around the wif connections and maybe they got dirty or wet with fuel even though i didn't dis connect them. What can i use to clean them.

 

engine cleaner, rinse, compressed air to clean and dry futher.

 

i pulled the plug on the sensor yesterday and cleaned it with elec cleaner and blasted it with air on the male and female and the light won't go out. there is no indication of water in the fuel. i got 1 ohm when i tested the female part of the connector. any idea what the resistance should be through the sensor itself or can i just take it out and water test it to find out if its working right?
