Hello, never really had problems with my truck until now, hoping you guys could help me out here.
2007 F150, 5.4L 148K. Just had plugs replaced (7 out of 8 cracked lol), catalytic converter on left side replaced. Leaking fuel from this part. Can someone tell me what this part is?

throwing code P0420

 

P0420 is a passenger side cat code.

 

Not sure if the first reply went through. So I'll try again. Thanx for the reply. I knew that it was a cat code, but not that it was for the right side. Had a feeling that's what it was though as I did not replace THAT converter. Any idea though what the part is that's circled in the photo that is leaking fuel? Thanx.

 

I don't know what the part is........but don't drive it until you get it fixed! It may be a fuel pressure sensor, but don't take that to the bank.

This is why you don't want to drive it.



Boy do I love working on this thing!

That is my daughter's Chevy Impala, but gas doesn't care which brand you drive it will burn anything!

Good luck.

 

WOW! Thanx for that. That'll put the fear of God in you. Going back in the shop 1st thing on the morning.
