I have a 1994 G20. It dies on really hot days. After doing a little research I have discovered these vans have a module with the number 10052954 or 10052973 sometimes located under the driver's seat. I can't find mine. It's actual name is something like fuel pump cycle module.

 

post the engine size and i will look up the fuel system wiring diagram.

 

!994 G20 350 single gas tank. I need to know where the module is located.

 

nothing for hot fuel module...must have another name by gm.
