Can anyone give input into fuel gauges,not working.Are they electrical or pressure and do you know how to get access to tanks to correct? Thanks in advance.
They are electical and more than likely your sending units. There should be access panels above each tank that will allow you to access the sending units inside you tanks. The sending units are available at any West Marine or other supplier
Try cleaning the electrical connections in the system first before giving them up for dead. Sometimes it's nothing but a little corrosion or bad ground that fouls up a gauge.
Welcome aboard. You have had good advice already. Check the connections and make sure they are clean. You can pull the sender and put an Ohm meter on it and then move the float up and down. You should see some change.
