If anyone is about to replace their fuel sending unit or fuel pump and has it removed from your 2003 GT Mustang gas tank, can you please take your fuel sender's empty and full ohms value readings before you reinstall it, and share those readings with the rest of us. These ohms readings will play an important part of troubleshooting your fuel system if you continue to have incorrect fuel level gauge readings after you replace your fuel sending unit. I forgot to take the readings when I replaced my fuel pump module assembly. Thank you for your support, Tommy.

 

I probably need to do that cause about once a month my gauge will read inaccurate but i'm being lazy once it threw a code for the sending unit but it was a one time occurence.

if i do I'll post numbers

 

DP again...sorry. How was the replacement? you had to drop and empty the fuel tank correct?

 

Yes, to replace the fuel pump module assembly it's best to do it with an empty or near empty tank. Email me at: Chevy66@hawaii.rr.com. Thanks, Tommy.

 

I had a short to ground on the sending unit and had to drop the tank last month. I don't rember the values though. Why don't you go to NAPA and ask if you can test one in the store. same goes for ford parts dealer. CASE CLOSED!

 

I tried that, I haven't found a single automotive parts store that was willing to let me do that. They simply don't want people testing products that they have to sell. That includes the Ford Dealership Parts as well. I guess unless you are really good friends with someone who works there, they won't let you do that. Thanks for your support and ideas.
