2001 3.0 smoke test, any pointers?

[Summers22]

Going to run a smoke test on my RWD 01 Ranger 3.0. Getting a persistent P0455 code. Where would be the best location to tie into the evap system? Any youtube links are helpful as well as I have never attempted this type of troubleshooting. Thanks

There is a test port and you can get an adapter for the Evap for like $20 on EBay. Test port should have a green cap on it, maybe grey, and be located on the drivers fender liner under the brake master cylinder, somewhere in that area.

Not sure about yours but it’s probably what I’ve dealt with, the Evap line that runs to the rear is partly made of steel and tends to rot over time. Want to say it’s a 1/2” line. I got some 1/2” fuel resistant rubber line and a coil of aluminum 1/2” line and rebuilt the factory line like that. It runs along the inside of the drivers frame rail.

Thanks a bunch, Google told me the test ports started in 2003, I will inspect that line. I'm hoping its not a line on top of the fuel tank. The one repair done to this truck before me was a fuel pump and I can visually see a portion of fuel hose, that is not OEM, so I hope to rule that out because I have rusted bed bolts, what a chore.

Test ports were at least as far back as 98, because every 98-11 that I’ve been under the hood had it in the same spot.

I see your rusted bed bolts and raise you what my F-150 has (not by my hand), and what my 92 Ranger had (I resolved that)… carriage bolts tack welded to the bed…

I got 2 bolts out, 3 wouldn't budge and 1 had a torx bit snapped off flush in it. I'll find the port and think about the adapter. I was hoping to have a spot to hook into that didn't require anything other than the smoke machine.

I ran a smoke test on my evap system a few weeks back. I didn't bother with the test port. Rather pulled each of the hoses going to the evap purge valve and injected smoke that way.

I wasn't chasing a code. I had a strong raw fuel smell. Black tubing on top of the fuel pump assembly had rotted wide open. I could get the old off and new on without removing the bed or dropping the fuel tank.
