Sadly a lot of people are not aware of the laws now for antique plates (not grandfathered in) and I still see a lot of older cars with them being used for everyday driving.

As for emissions, thankfully in NH, any car over 20 years old is not required to have an emissions test.
eeeyep. A lot of these states where the green activists control legislation it seems like they're using the DMV as a utility to get old cars they donlt like off the road regularly.

NH is a great state to live in, though. I'd say just about the most free state in the country.

I'd rather just beat em at their own game. I'll figure out where I'm losing pressure.

Besides, even if I did do soemthing like that, there's no way I'd drive a C4 with a license plate forced on the front by law. That would drive me nuts.

Good luck. Moving isn't easy, but it is an important thing to consider. I won't be moving anywhere any time soon that doesn't have a reasonable degree of personal individual liberty.
Sadly, the very term 'Individual liberty' is blasphemy these days. Freedom is scary for some foilks, it seems.

But whatever. I'll figure it out, I guess. I mean, I'm glad to know the tank isn't holding pressure but it's just more dumb sht they're throwing at us legislatively.

My guy in California clamps off the line for the test. The 90 has the identical strategy that my cars here have, so they need to clamp the vapor line for the tank test.
Yeah, they're clamping it but they said to turn the car off when they do the test. Which I suppose is irrelevant.

But, yeah, they're clamping it in the right place.

When I drop it off at the shop this week they'll find it with the smoke machine.

It's been a couple of years since I replaced the fuel pressure regulator and the fuel line o-rings, but they should still be good.

Canl' remember whether I installed o-rings on the new fuel filter, though. I was never sure about doing that. Seems to be varying opinion. Just looking at the FSM a minute ago, it does show them, so I guess I should install them.

Not sure if that would cause a no tank pressure at all situation, though.

You got 2 choices really.....Sell the car or move. I promise you, as you have been finding out, they will always find something to keep it off the road.

I can think of two possibilities that are easy to overlook:
A: The seal and gasket under the fuel sender/filler. They will find this with the smoke machine if they remove the gas door and rubber boot.
B: There is a very short hose in the metal vapor line adjacent to all the brake lines where they go into the ABS compartment. About 4" long. You can check this visually without a smoke machine. Forward of the LR tire.


I replaced every last fuel vapor hose from the tank to the canister yesterday. From the tank to the canister is all new fuel hose.

That one in the photo there with the brake lines is one of them that I replaced. There's also another short one, about four inches long, connecting two steel lines there by the differential housing. I replaed that one, too.

Coud be that gasket, but that's basically new, too. A couple of years old, if that, when I replaced the fuel sending unit.

But, yeah, you're right about the liquid lines. Was just thinking out loud there, I guess.

I forgot about the one by the diff.

If you have a tire pump, blow some air into the tank from the canister line. Use soapy bubbles on a cloth to wipe areas of interest. Particularly around the sender plate gasket. Has it passed the tank emissions pressure test since you last had the sender out? If = no, I'd check there.
Yeah, replaced those two hoses, too.

I replaced all five rubber hoses. The two that cnnect to the T on top of the tank, the one by the differential, the one down by the LRwheel and the one by the manifold.

Then I replaced all of the canister hoses again while I was at it.




Did not replace the fuel tank pressure control valve up by the canister, circled in red...

The funny thing is when I went back to run it through again, I went to a different lane on the chance that the guy who inspected it yesterday didnlt know what he was doing.

But wouldn't you know it, the same darned guy who failed it the first time through was working the lane I went to today.

That's the kind of luck I have. lol...

The guy said the tank isn't holding any pressure at all.

I replaced every single fuel vapor hose from the left side of the tank there by the the gas cap on the left hand side all the way to the canister.

Gonna drop it off for a smoke test in a few days.

Really hope it's something as simple as a leaky injector or an o-ring or something.

Not really up for replacing fuel lines and not much time left before the tag expires.


theres many places besides the hoses that can leak pressure. For instance one of my Buicks had the evap small leak code. Took me a while to figure out but long story short: the fuel pump housing flange was cracked and wouldn’t hold a vacuum. And yes, you could clearly smell gas after a fill up

Yeah, it doesn't really make sense when they contend that they're only testing the evap system for pressure when pressurizing the fuel tank pressurizes the entire fuel system.

I dunno. I'm greatly annoyed by this silliness, though. Gonna drop it off Thursday for smoke.

Should just buy my own smoke machine with thr money that'll cost. Or make one.

So after they put you through the wringer over and over, and finally find a couple tiny bubbles coming out of a pipe somewhere, is the world going to suddenly become a nicer place with no more global warming or smog or everything else? Yeah, I know the standards are clearly written and reality is the car either does, or does not, meet the standards. But the amount of time, money and energy being expended on this by the state AND the owner seem all out of proportion to whatever terrible evil is being perpetrated by the fuel system.

Well I'm certainly not gonna just throw my hands up and say umkay...you win...I'll take it off the road and buy an vehicle deemed appropriate and conforming to the standards of the Green Gestapo. Particularly given all of the time, money and energy that has already been expended since the day it got dropped off on a carrier. It's nothing new. Just another day as far as that goes. The only exception being the State sticing its nose in there.


But yeah, I agree with you in scope with regard to a couple of bubbles not changing much of anything.

I didn't mean that post to suggest YOU are deciding to put too much time and effort in, but rather the regulations as written seem to cause unnecessary hassle for both the inspectors and you. Volcanoes blow their tops, forest fires burn thousands of acres, China and India and many other places have no restrictions on anything - but here, we have to obsess endlessly about a vehicle which might possibly emit a faint whiff of gasoline if you stick your nose right up under or inside the nooks and crannies. Is it REALLY worth it, and if so, to whom? And why?

Like I said:

From our local weather here:
Wildfire smoke from the Alberta wildfires has made it all the way to the Great Lake and New England, generating a light haze to our otherwise blue skies. Such an occurrence isn’t necessarily uncommon locally. The last few years have featured several instances of California wildfire smoke going coast-to-coast in the upper level flow.

And
https://www.nytimes.com/2023/05/09/w...vacuation.html


BUT we can have regulations which clamp down on a hobby vehicle which has less of a leak than can be detected.

I know, I'm preaching to the choir. It just gets me riled up at the utter stupidity of it all.
