New -10% OE-Style Tank Module Installation Kit for Dual Tanks

Yes!  It is possible to install Holley's OE-style fuel tank modules in dual tank applications.  Provided that the module is made for that tank (such as the 12-308 in dual tanks in Chevrolet and GMC C- and K-Series Pickups from 73-87) this will work perfectly--with the right installation components Good news:  We have put all of this together in one kit to make your life easier!  Here's what is included:

  • -6 AN Female to 3/8-inch Hosebarb Adapters (5): Provides inlet fitting for the EFI system as well as on the checkvalves
  • -6 ORB Port Plug (1) : Replaces the return fitting with this plug
  • Earl's Vapor-Guard EFI Hose, 3/8-inch (10 ft): Provides enough hose if existing hard line is used*
  • 3/8-inch EFI Hose Clamps (10): Look and seal better than worm clamps
  • 10-Micron Fuel Filter: Perfect filtration between tank and EFI system.

Checkvalves?

You may be wondering why checkvalves. After all, the enlightened reader will realize that the fuel pumps used in these modules have checkvalves. But because each of these modules have their own fuel pressure regulator inside the tank, if a checkvalve is not used then the fuel will push out of the energized fuel pump and flow backward around the fuel pressure regulator in the non-energized fuel pump, quickly emptying the operational tank and possibly overfilling the non-operational tank. By placing a check valve immediately at the outlet of each OE-style module this prevents that from happening.

Installation Tips:

Use no sealant or thread tape on the AN fittings on the EFI System. The fuel filter will usually needs to be installed in the engine compartment since there is not normally enough room between the OE-style Fuel Pump Module and the factory hard line. Be sure to check the complete run of the hard line to ensure that you replace every piece of existing fuel hose with the included Vapor-Guard Hose. Please measure your hose requirements before ordering to ensure that 10 feet is enough. If it is not we will gladly add whatever amount you require.

*The included 10 feet of Earl's Vapor-Guard Fuel Hose is usually perfect for those who are retaining and reusing their existing hard fuel line. Opt for 20 feet if your original hard line has been removed.  If in doubt about what you need, measure and then give us a call!
