Super details on 4-speed restoration

Hi, I need some help Id'ing which bolts to use for
zbar bracket to frame
trans to bell housing
bell housing to block

I've got a 4-sp car from Ca., it appears to have HD cooling or a/c modification, with a return line for the fuel system.
Do I need this?  I'm changing fuel lines and its going to a bear getting the return line back in there.

The return line is worth the effort.  In my experience, the cars without them tend to build up pressure in the fuel system when you shut it down hot, force fuel by the needle/seats and cause the carb to flood some extra fuel over into the intake, then they are hard to start if you try to start them back up in 10 or 15 min. after you shut it down.  I added a return line to a '65 that didn't have it and it cured that problem. 
  So in my opinion, the return line is definitely worth the trouble.

Ted,

I can send you pics or drawings of all of those bolts. I don't have thread sizes written down,
but I do have lengths, head markings, etc.
All should be black by the way.

Cool Brian, I'm thinking the same as I had to do a return line on my 65 wagon- it was a v6 car, no return and I did the FL out of aluminum on that one.    any tips on how to get that new one up through the frame?   

Mark, that would be brilliant.    Thank you!

It is possible to get that line in the car if you have the muffler/tailpipe removed on the drivers side and also have the transmission crossmember removed.  It is pretty much impossible with those items installed in the car.

I definitely have the hard starting hot issue, and also have an issue with pressure buildup in the tank over time. I currently have a non-vented fuel cap, would a switch to a vented cap make any difference?

Thanks, Rhett

Sounds like the vent hose coming out of the passenger side front, top corner of the tank has something obstructing the end of it (like a dirt dobbers nest).  If that vent is open, you will have no buildup of pressure in the tank. 
  The problem with the hard starting is the buildup of pressure between the pump and the carb.  Cars with the return line have a special fuel filter with a relief valve in them that sends fuel/pressure back to the tank down the return line after it exceeds a set pressure point. 
  Of course if your tank is not venting, then that is just going to magnify the problem of pressure building up between the pump and carb.

I had no idea there was a vent up there! is it accessable without dropping the tank? Anyone have a picture showing location/configuration?

It has to be clogged... I took the cap off on the first hot day I drove the car, the ank was lower than an 1/8th full - I gave the cap a spin and it shot out of my hands and hit another car! The tank made a huge oil can noise too..

I kinda wish I'd done a return line now when I did the fuel lines.. it would be easier to find a fuel filter anyways..

Ted,

Rhett,

Regarding the gas tank vent pipe, here is a diagram of where to locate and how it's supposed to be connected. The vent pipe does loop up into the trunk compartment and back down again. It's connected to the tank by a section of rubber hose.  Go to page 100 on this link.

Good luck,

John -

Thanks - now I get it! The tak hooks to the standpipe, etc.. right inside the RR wheelhouse..

I'll check the pipe end for clogs and check the hose for kinks....

Thanks again..

I got the main line in that way, now for the return line from Inline Tube.  I stuck a coat hanger into the engine end of the fuel line and that helped guide it through the frame.  That and my special guide words (^&*(***^^%$%))---((*&&^^)
