I have searched the forums and haven't found anything to address this so here goes;

I have been chasing an elusive evap leak for a couple weeks and droped the tank last night. Looks like there may be some leakage from the rollover valve in the fuel pump housing (presurised the tank to 3 psi with compressed air and used a gauge on evap outlet)
I can hear leakage at the valve.

I ordered a new rollover valve and gromet to replace, How to do without damaging the pump?

I also ordered a new pump seal since that could also be a cause of a leak that I read about here. Should I change the pump seal also or return, parts will be here tomorrow?

The tank was hell to get out so I want to make sure everything is good before I put her back.

 

I had an EVAP code set awhile ago, I checked my gas cap and it was loose, and the code went away did you check your gas cap?

 

Yes, ordered new one from dodge, replaced, reset pcm, no change
