Paycheck Posted July 13, 2021 Share Posted July 13, 2021 Ok. So I'm chasing down vacuum and/or boost leaks on my '05 LGT because my e-tuner tells me I'm running super lean. So, in an effort to leave no stone unturned I ask you...... What is this yellow thing between my MAP sensor and my intake? And is it directional? That is, does it matter what side of it goes to the IM and what side to the MAP sensor? Thanks, $$$ Link to comment Share on other sites More sharing options...
awfulwaffle Posted July 13, 2021 Share Posted July 13, 2021 It's a filter, nondirectional Link to comment Share on other sites More sharing options...

Mr-C Posted July 14, 2021 Share Posted July 14, 2021 If you changed the fuel pump you may want to check to ensure the o-rings are not damaged or not sitting correctly....chassed a lean issue for a while before having a shop figure it out for me Good luck!
