#ProjectSportsRoof – Vapor Lock – 351 Cleveland Part II

Welcome back.

I’m shaking down the partial rebuild of the 1972 351 Cleveland in my 1973 Mustang dubbed, #ProjectSportsRoof  (originally called SR-73, but reader keep asking me if could do MACH 4+ …yea, I didn’t think it was funny either).  New cam, lifters, rods and a few other things, need to be giving a good working out.  However, fuel issues have popped up.  

Suspected vapor lock, but not sure, so I’m taking it one step at time.  Step one insulate the gas line from the block.  Here’s the video and results.  I could have edited a bunch out but I wanted the viewers to see it as it happened – in this case it’s more like HEAR it. This is my way of saying the video is ….um…not great!!   Watch the video and then give me your opinion on which option below you want me to try next.

         1.  Fuel Pressure test (because it might not be vapor lock)

         2.  Another option is to install an Electric Fuel Pump near the tank. This pressurizes most of the
         fuel in the lines. Fluid under pressure is harder to vaporize.

          3. Other options include installing a Phenolic Carb Spacer and/or a Carburetor Heat Shield to
           keep the carburetor cool.

         4.  Swap from an 850CFM to 750 or 650CFM Carb (because it might not be vapor lock)

Find the comment box and let me know which one you want to see attempted or email me at AGCarrestoration@cox.net.

Thanks for checking in.
