Thoughts on removing the vapor recovery system on a 73 911 T

[kazooward]

Just beginning to put the luggage area back together on a 73 911 T Targa I received as a "basket case" with most of the parts not labeled and in boxes. I would like any advice members would have on reattaching the fuel vapor recovery system. Specifically:
1) Since the car is to go on the market as soon as I complete the restoration, will the absence of the stock recovery system reduce the car's value? The car will not be restored to show room levels but is definitely at a Hagerty level 3 condition.

2) Are there any "drivability" issues associated with the recovery system such as power, acceleration, ease of maintenance, cold starting, etc.

Finally, the car originally came with factory A/C which was removed before I obtained it. The apparent location of the windshield washer tank seems unusual. The bracket, tubing, and wiring are all at the upper driver's side of the trunk near the brake fluid tank instead of down at the front. Seems strange since you would be spilling washer fluid all over the trunk carpeting when trying to fill it. Has anyone heard of this arrangement?

thanks for any help or advice

There are no drive-ability issues associated with the vapor recovery system, either with it present or removed (assuming you don't plug the fuel tank venting). But given most peoples attitudes towards so-called "longhoods", its probably in your best interest financially to reinstall it. Cars with all their original parts and systems intact tend to bring a higher price.

The washer tank was moved to the position you describe on all early cars with factory AC fitted. The front AC condensor/fan required the space normally occupied by the washer tank. It was a very crude modification with just a rubber strap sort of barely keeping the washer bottle in place, indicative of the low importance Porsche placed on AC in 911s.

I have to politely disagree with Daves911L about "drivability issues". The system keeps fuel vapors out of the cabin and in severe cornering and driving they tend to be pretty bad AND dangerous.

My evap system had been removed by a previous owner and I had horrible gas smell all the time. Using the PET diagrams I completely rebuilt the system. Finding one of the canisters was difficult and you'll see a strap to hold one behind the driver's side headlight. I couldn't find one anywhere so it's wedged in there with a chunk of 2x4 and some bungee cords. The black canister under the dash in the frunk was there but disconnected.

The up side is safety and no gas smell. I'll bet the lack of gas smell will translate into a few more dollars for your baby.

BTW I also have a '73 911T but with a '75 engine.

Best,

Tom

I agree with Grizzfan, keep it in place. It works very well.

grizzfan is ABSOLUTELY correct about the gas fumes. I had all the pieces hooked up but they were 45 years old on the 70. Bad gas fumes. Replaced all the associated hoses with new and no more fumes. The braided hoses were all hard and brittle and broke into pieces upon removal. Anyone who looks at your car for purchase will not like the fumes. Connect everything.

I had a fumes problem on the race track with mine removed. Eyes watered.

I now have an eval canister that I bought from my pal at Mikes914s. He has a hole trailer full of them

[kazooward]

the system seems in good shape so I guess I will reconnect it
