Hope that Evap switch takes care of it. I think I pointed to that when we were discussing mud packed and not getting gas in back when you got it. The rule is no air out, no gas in.
I have had to replace gas tanks on trucks that have had a non evap system vent hose kink. The fuel pump damn near crushed the 55 gallon steel big truck saddle type tank flat from the inside. These pressure inequalities can get powerful.
I currently have a similar problem on a motorhome's septic tank. I think some mud dobbers got into the vent pipe and made a home. Oh the air in the MH gets ugly when any volume is flushed! Water(and stuff) goes into the tank, the same volume of air has to come out. If it can't get out the stand pipe vent it burps back into the toilet. Ewwww! Same principals apply(but for the nasty sewer stench verses gasoline fumes). On that note.....you win.
Oh Mark, the reason the vehicle system has the evap can and switch is for putting gas into the tank. The system is otherwise completely sealed. The fuel pump builds pressure pumping fuel to the engine at a given amount of supply volume and pressure. What ever gas the engine's injectors does not use is recycled back to the fuel tank. That is why if your gas cap is loose it will throw a code for a (vacuum)leak.
The evap can usually contains charcoal to absorb(some of) the nasty vapors as they flow out into the atmosphere as a function of burping the gas tank while filling it. That switch opens the vapor pressure flow to this vent while the key is off and closes to seal the fuel flow (pressure/vacuum) system while the engine is running. Someday they hope to absorb all of that vapor back into the gas stations tanks rather than have them suck in fresh air and your evap can passing fouled air.
The Check Engine Light has been off for a couple of days.
In my 33+ years of driving, I have only had one brand new vehicle. That was a 2003 Dodge pickup 4x4. I have always bought used. This truck now feels/drives like a new truck. On the highway it rides better than some of the cars I've had.
I've finally chased/fixed the fuel pressure issues on my Cummins and have ordered an old-school Edge Comp box for it. 5 levels, each with 5 sub-levels of low-boost fueling. 40/60/80/100/120 hp for the main levels; 150/200/250/300/350 lb-ft.
No_rice, True, but His Imperial Majesty Lord Emperor Andrew Cuomo the First ( aka the Governor of the Imperial State Of New York ) has already made noises about banning TDI's until they are properly neutered. Mixed in with a rousing speech about how He, and He alone can protect mankind from the Capitalist Running Dog Lackeys..... But that's just my interpretation of his usual self indulgent, and self praising speech on how he's going to sue VW.
He is the kind of dude that takes credit for other people's work, and has the State Police pre-running his path. Their job is not to protect him against assassination, but to steal yard signs along his route so that no possible criticism can touch his eyes. ( especially the ubiquitous signs calling for repealing the SAFE ACT. Anti-frakking signs are acceptable, as that is his Imperial Whim/self affirmation ) That's not a joke. They actually do that.
So I may have no choice but to "fix" it or have the Governor steal my car at gunpoint.
In other news, mice ate my car again.
Peppermint? Dryer sheets? Sarin? not sure what to do to keep it from happening again.
