should I replace fuel pump?

[simple]

My fuel gauge doesn't work properly as it usually will stay on the full mark. I'm thinking it might be the fuel sending unit and I'm wondering if I should replace the fuel pump as long as I have the fuel tank down and everything opened up?

What year and model do you have, also how many miles?

 

some sending units and pumps only come as a 1 piece unit.

I have a 1997 Z71 with 99,000 miles. Yes, you are correct that it might come only as 1 piece. I haven't had the time to check if this is the case, but what if they don't come as 1 piece? Should I replace the fuel pump also?
