wait, is the over pressure valve the same as the tank pressure control valve? meaning the vacuum operated valve located at the charcoal canister thats connected to the fuel tank?
No, not the same. The over pressure valve is above your rear axle - more towards the drivers side wheel well.
The plugs for the exhaust manifold are essentially blocked off tube nuts. NAPA should have them.
The tank will vent without the TPCV, but since you are keeping the charcoal canister, then why not keep it? It is just 1 extra vacuum line. With it, the fuel vapors will be sucked into the carb to be burnt.
The fuel filter in the fuel bowl vent line to keep charcoal bits from entering the engine is my idea because I read about this happening to someone else. I figure that it's a cheap and easy way to prevent this from happening. You could even use a plastic, see-thru filter.
You don't really need it because you already removed the TVS valves and CCV.
ok the valve is in the car now so ill just leave it
i dont mind adding a filter just to be safe since it will be a while before i can upgrade the motor so if it will help this engine do all it can ill put one in. but all the fuel filters i looked at for this car were weird and IDK how they would connect to the lines since they are female on both ends. do you have a recommendation?
I know I'm a bit late here, but isn't the line you've got hooked to the "H" port on the carb supposed to go to a tee junction off the PCV line instead? That's how it reads to me, anyway.
Very similar to what I was doing with mine, or trying to at least as I've been stupid-busy til now.
Pic shows what I started with. Note I deleted the control valve at the time, but since been reinstated. I now have a new control valve and CCV. I'm currently trying to find a suitable replacement caniste
r as the original is now discontinued. Need to find something that will fit it's place first go as I'm in NZ and postage gets expensive quick!
