CARB Engine Conversion, calling Vettezuki
Help me compile the list of parts I'll need from this donor car before it goes to the junkyard.
Charcoal Canister Catalyst Sticker O2 sensor Catalytic converter Fuel pump OBD2 Connector Will I need anything else since this is a 96, so its OBD2 and also its a different type evap system? |
ECU
AIR Pump (if it has one) Harness I'll think about it more. |
Fuel tank since yours probably doesn't have a pressure sensor in it and the '96 will. You'll also want to keep all the exhaust before the cats. The cats are supposed to be near their original placement in the exhaust.

Fuel tank aint gonna swap over. What does the pressure sensor look like? Im sure I can fit it to the stock tank.

Something like this, got it.
Ron do you know if the tanks are vented differently? Thanks! Attachment 898 |
In my case I programmed out the error code for the tank pressure sensor. Kept the original C3 tank. The ref was suspicious, but let it slide. He DID make me change the charcoal canister.

I don't remember what mine looked like but I just bought a new tank that had the fitting in it (Eric's tank was too rusted to use). I got my tank from Rock Auto and I had a 20% off discount so I think the total came out to $180.

The diagrams found don't show a fuel tank sensor, but some do show a leak detection pump.... Evap self testing was pretty new in 96. All the info I found from Chrysler is vague. Some vehicles had leak detection pumps and some didn't, even in same model lines. Most early evap self tests used other sensors to check evap operation. The pcm would look at MAP ( manifold absolute pressure) and look for a change in manifold vacuum when the evap solenoid opened. Some systems would look for O2 sensor enrichment readings as the solenoid opened.

My 73 F250 built in Oct 72 did not have a charcoal canister. My cousins 73 F250 built in early 73 did have a charcoal canister. Back then the rules went into effect on Jan 1, now they apply to the model year. Made getting my truck smogged a PITA as the young guys did not believe me on that.

I don't remember the last year but into the 1980's.
In approx 1977 I bought a 57 Pontiac and had to install the temp controlled vacuum advance to register it even though it didn't require semi-annual smog checks. Retro ones you cut the top radiator hose in installed this temp controlled valve, I just bent the hose and attached it at the end, the smog tech laughed. Had to remove the old style crankcase vent also, those were a 1inch metal tube that entered the engine near the distributor and snaked down to just below the bellhousing. My F250 has valve cover breathers with rubber hoses that snake down to below the engine and dump the fumes there. :) I bought the wife a garden tiller about 5 years ago - CA only model. It ran fine then after about 40 hrs started quitting on me. Turns out the CA special has a rubber hose as a crankcase breather that feeds into the air cleaner and those small engines can't adjust for even a small change in air/fuel mixture. Took the hose out of the air cleaner and it runs fine. Fuck CARB and the AQMD. When they find a way to stop China's air pollution from coming here on the natural wind currants then I will consider playing by the rules. |
