How do I stop vapor lock?
I've been looking for this style filter for a while. My 3/8 sending unit has a 2nd fitting that I can run the return line to. Can I use it as a return?

^^Several causes^^
'70 was the first year SOME cars had the evap fuel tank emissions controls. You need to determine if yours has it. Read through the emissions and fuel section of the 70 manual. Determine if the tank is actually getting vented (plugged vent?) You can remove the cap to do so
Alcoholized fuel lately, worsens fuel boil problems
Best thing I did for mine (before going to EFI) was to build a vapor return system using a Wix filter with built in orifice, adding a thick carb insulator, and using a rear mount electric pump
Wix 33040 (5/16) and 33041 {3/8}
Problems are worsened by a poor fuel pump, (bad valves) by an overheating engine, and of course hot weather.
