Ok guy 1 question..... I have a 2001 limited edition 4 door blazer and I need to know if I can use a pump off a 2003 4 door blazer?

 

As long as they both have plastic tanks. I dont think theirs a differance between them, and once you have them both in your hands youll know for sure then!

 

My truck is a 2001 limited edition Trail blazer with a 4.3,..it's not a regular blazer.......But it is made like the 99' and up regular blazers.

 

yea u can use the fuel pump if u want to, as long as they are both either 18 gallon metal tanks or 18 gallon plastic tanks.....i would just take apart the sending unit and replace the pump youll need a flathead a pair of slip joint pliers and 5 minutes the pump is reall easy to change in those plastic sending units...

 

Thx guys

 

Your truck is just a trim level on the standard S-series Blazer so saying that it is "not a regular blazer" is not true when talking about pretty much anything other than the optional trim pieces that make it a Trailblazer trimmed Blazer.

That said, comparing the part numbers on RockAuto.com should give you definitive proof.
