Stainless Works Exhaust Downpipes/Catback

[Thatblackraptor]

Just finished installing the Stainless Works downpipes and cat-back exhaust and have an interesting issue!

The truck will absolutely stink of gas inside the cab on a cold start. I had an exhaust shop check for exhaust leaks and all is good there. I do occasionally get the P0420/P0430 codes for the cat efficiency but am planning on use the spark plug non-fouler spacer trick for that issue.

Is this just the life with new high flow cats? I can't imagine it would be this awful but it does smell like someone dumped some gasoline on the carpet in the truck.

Yeah usually you get that smell with catless downpipes. Those cats on there must be 200 cel for it to smell that bad.

So this morning I discovered a huge fuel leak on the mechanical fuel pump on the engine. One of the connections is just shooting gas out. Not sure how that happened.

Posting incase someone else runs across this in the future.

Disconnected the fuel line and inspecting the o-ring showed no rolling of the seal or damage that was visible. Reconnected the line and all is good now. No fuel leakage.

Good find. That could have been a bad day.
