I have had another bout of what I perceive as vapor lock.. its been warm again out here in MT, and I took the car for a several hour ride. Ran flawlessly,,, until I got back to town,  some slow driving, some longer idles, and I was at about 195 on the gauge.   to access were I live requires a pretty long, steep hill and I started up and half way up, it stalled and wouldnt start.  I back rolled it down the hill, tried to start and the bowl was empty, and not filling as I tried to restart.  and the fuel pump was VERY HOT.  just my thought is its getting vapored in or around the fuel pump and no gas is gettin to the filter bowl, add in the steep hill and it just stalls.  After about 2 hours of sitting, I went back and it fired right up, bowl was back to full.. pump was cool to touch.. 

so I got the thinking about going to a electric pump to try and alleviate this.   I noted Russ A. seems to think they have worked well from him as well as others.

so, my question is to options.  Can you add a lower pressure pump, say 3 to 5 psi and use it as a supplement to the mechanical pump, so as to continue to push fuel if it vapors, or would it be more prudent to just go with simply full electric and set it at the 7 psi that is required?  

Also, what brand has been found to be most reliable,  I see edlbrocks at the store, they have a lower pressure one  30 mph and and another one that goes up to 38 mph, I but im not up on these things so was just wondering..

any insight would be helpful

I use FACET fuel pumps which are high quality. You can run them with the original FP if its in good shape. A return line to the tank is a great idea. Insulate the fuel lines in the engine bay as well.

I have the line from pump to filter wrapped in insulated reflector tape. I tried to put it on the pump, but all the odd surfaced and oily surfaces didnt stick well.  I should also mention, its an ac car.  .  I will look into the pump you mention.

1963 RHS A/C kick panel - photos needed

Posted by SK on June 2, 2025 at 2:20pm 2 Comments

Could someone post front and back photos of the 1963 right-hand kick panel with A/C?

My car didn’t come with the original kick panels, so it's a bit of a mystery to me how I should cut the backing board and carpet to fit around the A/C.

Many thanks,

Edelbrock Carb Block off Plates

Posted by Chase on March 12, 2025 at 2:05pm 14 Comments

Hey guys,

I have installed the same Edelbrock carb and have done everything the same as Jason’s carb and intake project. In the spring and summer months the car starts, runs and idles great! In the fall and winter months on a cold start, the car starts awful and wants to die until it warms up. I have to keep my foot on the throttle until it warms up or it will idle just terrible and try to die. Once it’s warm, it runs fantastic! Whats going on here? I was thinking of removing the…
