Hi all

Once a month i get evap related DTC.
First purge solenoid,then gas tank solenoid DTC

A week ago vacuum leak DTC appeared
And what about tank pressure sensor?never has FTPS related issues.

Anyways ,already made a mistake and ordered wrong replacement FTPS.

Took my tank apart from the vehicle.all the hoses looks good..

Then discovered that my new replacement FTPS belongs to F150 probably...wrong connector and orientation..i have no idea about F150 wiring

Cleaned all the hoses with air pressure and checked vacuum..all good.

Then noticed about corroded fuel pump connector:

The most corroded pins belongs to pump and fuel level wiring.

Cleaned and lubricated with dielectric grease

Have no idea what is the reason for corrosion.will try to investigate this issue...pump harness goes to pcm thru passenger exhaust manifold...
