How to Replace a Fuel Sender Unit and Fuel Pump Miata MX-5 MY:1994

How to change or replace a fuel sender unit with fuel pump on a 1994 Miata. This is a Spec Miata Race Car. Owner Dan Tsuchiya (aka Sir Fix Alot) shows us how to test whether it's the gas gauge in the dash or the fuel sender.

May not be the fuel gauge, more likely the sender unit....sometimes the resistance reading from the sender can fluctuate and then it reads either high or low. Try changing out the sender unit first then if that doesn't work, try the gauge. Good Luck.

sir fixalot like to ask you what can it be if my fuel gauge always marks the wrong level amount of gas? at times it mark less gas and other times it marks more than it actually haves. do you think it is my fuel gauge??

funny how things work, I disconnected the fuel sender unit wire to the the ohms reading, then I put it back tighly. noticed the fuel gauge is working again, came down from full to where it should be now all by itself. must have had a loose ground. anyways thanks for the video, I am getting a repair book off ebay! cheers!
