Vapor Separator
« on: June 23, 2011 - 09:46:47 PM »
I am about to reinstall the Gas Tank in my Wife's 73 Challenger.  I purchased the correct 73 tank to go with the Separator.

1 I plan to clean up the Separator.  Is there anything inside the Separator, or is it just an empty can?

2 I don't know if I have anything of the original parts from the Separator forward.  The old pics on here are gone, can anyone help out?

3 If I terminate the large line without original "stuff" should I cap the line, leave the hose off, or run a line to some particular point, other?

4 Should I replace the blanket on top of the tank or leave it off?  I worry about the moisture rusting the top of the tank out, like the original.

5 Thoughts on painting the tank with spray-on bed liner?  rust prevention??

1/ What's in the separator? Beats me.  :dunno:
2/ From the separator forward, It goes from the separator to the charcoal (usually gone by now) canister (Engine compartment) and then to the carb.
3/ I ran mine to the highest point above the rear axle and put a fuel filter on it to keep out dust. Good idea? I'm not sure. Maybe someone has a better idea.
4/ IMO, yes
5/ Sprayed mine with regular undercoating. (tar kind of stuff)

Well I can say one trip thru the dishwasher ....(don't tell my wife hehe) and a little more play and she seams to have broken free.

I put a nice coat of high temp primer on and will see how long it takes to get the tank installed.

I now have to connect the spider web of fuel lines, get a blanket for the top of the tank, blow out all of the main fuel lines and hope the fuel pump and carb are in good shape.

the original blanket was a tar coated cloth type deal
 IMO replace it , I used plastic packing , minute bubble wrap / foam as it will not hold water

I had considered spray-on bed liner.  I have been talked out of it ...

The top of her tank had rusted out (a perfect shape of the old blanket.) and I was afraid the problem had been moisture getting trapped between the mat and the tank.

NEXT:

Somehow over the years, the bolts that connect the VS to the body have gone missing(mixed with other bolts).

Anyone have a pic of the correct bolts (so that I might dig out the correct ones)

I don't have a picture of those bolts but I can take one tonight.  They have a large washer on them...3/4" maybe.

That would be appreciated .... I think it was two bolts, not one long shaft, but I will wait to see what you have.

Yep, it's two short bolts with a large captive washer on them.  I'll take a pic tonight.

The fastener guide doesn't list those bolts.  I got a picture of the correct ones(off of a 74) from a guy on Moparts but  I can't seem to find it.  I looked in my tub of fasteners but don't think I found a bolt that matched the ones pictured exactly.

My VS had an impression of a washer on the mounting tabs.  I looked through my fasteners and found two bolts that had the same sized captive washer and that also fit the nuts on the shock x-member bracket.  The only thing I'm not sure on is the length of the original fasteners.  I'm using a 5/16" bolt that is 1 1/4" long.  It has a 1/2" head and a 3/4" captive washer.  The bolts are phosphated.

Once I pulled those fasteners off the car I remembered that they may not be the correct ones.  The washer size is correct though.  Just the overall length is in question.  Sorry

No problem, I appreciate the effort.  I will wing it, and dare anyone to crawl up under there and complain :)
