Corvette Fuel Line Connected

 I've been struggling with the fuel line for the 'vette.  With the carburetor sitting on it, I either needed to replace the carb, or custom build a fuel line.  I did not want one of those "adjustable" pieces of garbage, and no one made a dual-inlet fuel feed line for a carburetor that was modified with another fuel metering block (you know, because I changed from a vacuum secondary to a full fuel secondary).

I started out with one of those $30 dual inlet adapters that claimed it would fit (9.375" between inlet centers).  It was 0.250" off, so I tried to bend it to fit, and ended up with a fuel leak in some pin holes.  It was very thin wall, cheap, and had poor results.  That went into the trash fairly quickly.

Next, I bent some solid 3/8" stainless fuel rod, and milled a "y" trunnion.  Unfortunately, it never set right.

I bought a kit from Summit Racing that supposedly fit.  I mean, it had to work, right?  It had the 9.375" center-to-center, and listed a 5/8-18" inverted flare fuel inlet.  Turns out that's what fed from the fuel line.  When Summit Racing says "fuel inlet", that's not necessarily the fuel inlet.  Yeah, it's all wrong.

My final attempt was steel rod and a T block.  It took some effort flaring and bending the setup.  However, when I was done, it all fits, and I don't have a weighted system hanging on some rubber hose that will crack faster than a password in War Games.

And, with it all connected up :

Yes, I used some heat wrap on the fuel line.  I should have used it all the way to the carburetor, but I just didn't.  Now I gotta get the battery charged, and I can give it a shot and see if she runs on her own so I can tune the carburetor, then get the engine timed, and then ensure I have the transmission set up properly.
