What to run to evaporation chamber

toddbowie

On my 74 Ghia. should I run a new hard line under the chasis from the rear wheel well to the evaporation chamber or a hose between the 2 short existing lines?

Is the existing hard line clogged? I'd keep the existing lines if you can. I was able to clean mine out with carb cleaner, a bit of wire, a bike pump and an eraser.

Use the stiff wire and cleaner to clear as much crud as you can, blow some air through the hose, add more cleaner. Once air is getting through (gently) block one end with the eraser and keep pumping until you can pop the eraser off -- lots more dirt and rust will come with it.

No, they're not clogged, there is nothing running between the rear well and the front. The line by the gas filler runs into the trunk, under the glove box and ends there. There is another short hard line coming off a larger line that runs into the tank next to the main filler hose. Pictures of restorations I've seen seem to have a hose running next to the running board under the car from front to back to connect them together just can't tell what to hook the front to.

By the way, the Ghia was almost completely taken apart (except for doors and hoods) when I got it.

I'll see if I can snap some photos this week. Mine has a hardline in the trunk that exits in the passenger wheel well, has a soft line connection to the a long bit of hard line under the passenger pan to body bolts (held by clips) to another soft connection in the rear wheel well, clipped on hardline meets welded on hard line into engine compartment and then softline to charcoal chamber . . .

Might take me a week. Hopefully someone else has photos on hand.

Some pics would be great as my full scale model kit didn't come with instructions.

Held by clips at each body bolt:

Hardline runs under jack point -- joins a soft connection:

Into wheel well, held on by tabs

Runs along the inner fender arch

and into the engine bay

and then I think you know the connections from there Smile

Thanks a million! That helps tons. Just exactly where and what do the soft lines in the trunk go to and from?

Driver's side of tank:

Runs along side of fender goes up to top of trunk area on very held on by tabs right on top of trunk area. Hard to see -- there is one near each reinforcement pillar and another above the radio area, and one near the wiper motor.

Joins the center of this T which sits just in front of evap can.

Front of can -- loops around under bracket. Joins tee:

Rear of tee -- green arrow -- terminates here:

Rear of can makes long loop:

rests in the 'U' of the wiper motor bracket

Length of loop:

End of loop:

From the photos and your description the hard line under the chassis appears to be OK.

I would just insure the soft lines are hooked up properly and are in good shape.

That helps quite a bit. Thanks. It seems I'm missing a ton of hose and the "T", and the evap can. Is the evap can what is pictured next to the glove box?

I am reinstating the original emission system on my 1969 Californian Ghia to help eliminate fuel smells. I've draw a sketch based on your description. Does this look correct (anyone feel free to chime in)? I wasn't sure if the orange line is correct also what the the diameter of the hard line that runs to the rear (mine is currently missing)? Hopefully this sketch helps out others once it is fixed up.

The line running to the engine compartment is 3/16". It is a combination of line and hose as Danielsan shows in his reply. Your connections on the gas tank look fine to me. However, the canister in my 74 1600 DP has one more 3/16" connector which goes to the top of the air filter. This picture is not real clear but might show how mine is hooked up.

It is sort of a mirror image but is basically the same as you have yours with the exception of the extra line.

Hope this helps,
Todd

Here are some photos of 71s from the classifieds section -- where the hardline passes from the inner, passenger fender well into the engine bay:

It seems to be different on the 70s however -- not sure how the line gets into the bay on earlier models.

And fantastic diagram stcj !

On my 74 there is a small piece of line that runs through the right wheel well into the engine compartment behind the air filter stand.

Thanks for the clarifications, Todd you might want to double check that additional vacuum line on your charcoal filler, mine has what looks like a small pipe at that end of the canister but it is sealed and just a plastic spike not a tube. Also the connector on the air filter should connect to a vacuum source on your inlet/carb, how it works is that when you get enough warm air through the pre heat pipe in your air filter it melts a wax valve under where those two hoses connect that allows the connection between the two hoses to open and passes a vacuum to that round box under the air filter spout. This then shuts off the warm air supply to the filter and only draws cool air from the engine bay.

From 72 Manual:

Line E should connect to a vacuum source on the carb/manifold.

Cheers,
Chris

Thanks Chris. I'll have to double check that tomorrow when I get back out to the garage. I've been so busy working on my Opel GT project, I haven't worked on the Ghia for a couple months. It'll be a nice change of pace to work a little on it.
