Gauge bad maybe? Or maybe some resistance in the wire leading up to your instrument cluster?

That's the first thing I would check. I pulled my intake off to do some work. When I put it back on, I apparently didn't get the throttle mounted back on the same way. When I started it, it was running about 2500 rpm and there was tension on the throttle. Adjusted the cable and it was fine...

Exactly!

Is it just off on the high end, or is it off on the low end also. I've always been more concerned with how accurate it is when I'm getting close to being empty. Couldn't care less what it reads when full. Maybe you just need to give the float arm a little bend to get it to the right level. For...

I've seen other people mention the Meter Match system which does the same thing. TechnoVersions - MeterMatch for Analog Gauge Correction

Well, yes and no. Think of it this way..... The PCV valve is connected directly to the vacuum port, so it is pulling directly through the PCV any time there is engine vacuum. The breather is connected to the ail filter, but is much smaller than the overall air filter, so air can be drawn through...

What is on the other end of the hoses that go to the valve covers? I assume one is a breather and the other is a PCV valve? I don't recall it being common to have hoses hooked to both valve covers. Most instances I can think of, at least on these old Mopars, have a hose coming from the PCV...

Is the fitting not removable? Usually, at least on the air cleaners I have, that fitting is held on by two bolts. You would be able to unbolt it from the old air cleaner and move it to the new air cleaner base. Might have to pop the holes open though. I just bought a new drop base for mine and...

I'm on the opposite side of the others I guess. I just bought the insulation for my Barracuda, and am getting ready to install it right now. My air cleaner will be a close fit too. I am running a 3" filter, so I am going look for a little thinner filter element, or look into different drop base...

Yeah,... Looks like you have plenty of room to spare. You have options though. See how much taller the Air Gap intake will be and get a drop base air cleaner that gives you at least that much extra drop. If you want to keep your current air cleaner, I think you are out of luck though! :) Unless...

I read one article (I think it was an online Hot Rod article) where they were going with larger and larger carbs til they found the optimum. iirc.... they were doing test runs on a dyno. They watched manifold vacuum at WOT. They would do a pull and watch the manifold vacuum to see if the carb...

I have been doing a lot of reading on CFM to cubic inch needs. I ran across a formula that calculated theoretical CFM needed, but that didn't include the Volumetric Efficiency (VE) of the motor. Most good running street cars have a VE in the range of 80% - 85%. Higher performance cars might be...

Some people like to compare them to fully ported race intakes like one compares to the other. I noticed that they were basically the same too. They do the same thing on heads too. I think it's been proven that the RPM flows better than the Performer, hence it's higher power band. My thinking is...

I agree with you Dart. I have seen references ranging from 73ohms to 75 ohms in different readings. I don't think it makes a huge difference in those two numbers. To test my gauges, I set my power supply to 5volts and verified. My meter read 4.99 volts. I connected two 150 ohm resisters in...

Yes, when I physically saw the gas dripping, it was on the right rear quarter, but that was after pulling around to the left. I have a hard time believing that all that gas would have run to the right side without any of it spilling at the left (if it was the filler tube), but I don't know where...

Thanks 6Pak. I had heard that too, and saved the one out of the tank on my Charger in case I needed it, but hadn't thought about that on this issue. Thanks for the reminder. I will take a look at that too while I am under there to see if there is any sign of that leaking there :thumbsup:

"Pouring out" might have been an exaggeration, but it definitely wasn't a dribble. I would say maybe half a cup to a cup, which isn't a lot, but it's enough to make a mess and make me want to find out why it's doing it. Like I said though, only for a little while. Last time we filled up and...

I think I understand you. I guess I assumed the vent line came from the tank to the top of the filler tube to allow air trapped in the tank to escape as it fills (in other words, connected to the tank on the bottom and filler tube on top). It sounds like you are saying the that vent line is not...

So I finally got a chance to look at my car to see if there was a vent tube next to the filler tube on my car and there is. Vent line comes up the filler tube, goes around a loop and dumps back into the filler tube. I don't see how this allows the tank to vent, nor does it explain why I am...

Ok,... I'm an idiot!! For some reason when looking at the picture Dave posted, I was picturing the spare tire well in the trunk!:rolleyes: I see what you're saying now. I WAS told that the previous owner replaced the trunk. That being said,... even if he didn't. If that was my issue, I would...

Oh, ok. No,.. Trunk is in good shape with no rust, let alone any perforation.

Check for what? gas? I will look, but I haven't seen any signs of gas in the trunk.

This is on a notchback, so I will go out and look at it tonight and see if there is a vent tube that runs next to the filler tube. I know the previous owner said they replaced the fuel tank. I also saw online where tanks are listed as having 2 vent lines, so I don't know where those would be or...

So are you saying the vent comes up through the floor of the trunk? I've seen some models where there is a vent line that follows back up the filler tube to the filler nozzle. I didn't see that on mine though. I will look though. Car was filled until you could hear it start to gurgle, but didn't...

Hi Guys, Quick question.... I am getting a real bad gas smell after filling the tank and driving. I even had one time where I filled up the tank and pulled around (to the left) to air up a tire and there was gas running down from somewhere on the right rear quarter. It is a 1967 Barracuda. I...

Where does your exhaust exit? Out the back or does it dump under the car somewhere? Is it while you are driving, or sitting that you smell it the most? The only time I have heard of that is on old Suburbans, trucks with top caps, or station wagons, when you drive with the back window down. The...
