Hi, Restoring a Superbird in Australia and fitting new fuel tank. I would appreciate if somebody could post a few photos showing how the vent tubes fit to the rear of the tank. When I bought the car, it did not have a gas tank, so flying a bit blind. I do have the line that goes into trunk, but not sure how the second line should fit(I do not have one)
Also, I have a new filler neck, but cant see how it attaches to the rear panel. I may be missing a part.
A picture of the filler neck fitted to the body would also be appreciated.
Thanks, Rick
 
My car has the E.C.S. fuel tank. If yours has that tank, i'll gladly send some pix to you. That system has the metal tube that comes up into the rear right side of the truck.

Chuck could you send me the some photos of the gas tank vent line would sure appreciate it. I am the same boat as Rick.

Thanks Craig
 
I'll try & get some tonite for you.
 
if you have the ecs tank ( 4 fuel vapor lines from pass side of tank ) it's a closed system with the gas cap doing the venting. If you have the repair manual, it shows a pic of the line routing. But you have to be careful of the filler neck & cap. it has a special filler neck designed for only the ecs tank. the filler tubes will interchange with each tank, but the correct cap only goes on the one it's designed for. I like the original setup. I replaced all lines & used the correct replacements. If needed, I can still take pics or you can call me & i'll try to explain it to you.

Yeah, I don't know how to do pics here, but the above is basically the setup on a non-Calif car
 
I have a California car. Completely different set-up.

I am trying to find that special fuel tank filler neck for ecs on a 1970 Satellite. Do you know of a source? The original part number is 3404382 and it is not a station wagon. The car did not originally have ecs. Thank you
 
I found one in California at a Mopar salvage yard. Just make some phone calls.

Chuck
 
Thank you for your answer. Do you by chance remember the name or location? Thank you or you can send me a private response.
 
Sorry, i don't remember the name. I think i googled Mopar salvage yards for the west coast.

Before installing tank see how the internal vents go. One ends at rear of tank/car; one is at front of tank/car. The short vent over the differential goes to the vent tube at the rear of tank. If parked down a hill that shorter tube could be below the tank vent if it was installed on the front vent and hence leak fuel. If parked up hill the small vent is above the tank vents when the gas is at the rear of the tank and that line is attached so no problem. I have seen post were manuf have reversed those lines from the manual position.
