Fuel Vapor Separators

[Mopar Crazy]

I have a 71 340 engine with 10.5 to 1 comp. in a Challenger. At times, after the car has a hard run, It's hard to start. I have a good strong crank. I was told that the fuel was getting too hot. I was also told to put a Fuel Vapor Separator on, and that should solve the problem. Use part# X868.
I have  new 3/8 fuel line with a 1/4 return line to install.
Has anyone used a Fuel Vapor Separator with a small block???
Thanks

Pete, there's no reason that it won't work....give it a try to see if it helps. Let us know how it works out.

I had the same problem with my Charger before installing both the vapor separator and a return line.  The car is much less harder to start when it is hot...

Thanks for the advice,
I'll let you know if it solves the problem....

A fuel separator worked for me for the most part. My fix also took separating the carb from the intake heat. Even with the cross over plugged, I needed a 1/2 inch phenolic spacer between the carb and the intake. Check into those if the fuel separator doesn't quite do it.

What are your fuel lines made of?  I use rubber from the pump to the 'carb and it seems to help.  Also, I'm thinking about wrapping my pump to 'carb lines in heat resistant material...

I have a 1" spacer. I'm also running a rubber hose from the pump to the carb. My return line was no good. I just bought new fuel lines from The Right Stuff, Pre Bent. . I have to take out the old ones and trace the new lines... I also changed it from 5/16 to 3/8 aith 1/4 return. ALso installing a new 3/8 sender....
My tank has 4-vent tubes in front that go to the carbon canister.
Can I block off those vent tubes??? I'm not using the canister anymore...
