has a great discussion on dual tanks and high pressure EFI.
Basic rundown:
87 tanks with baffles for fuel pump
87 Fuel senders for in tank pumps
AC Delco EP 241 pumps
JC Whitney Motor Operated Dual Tank Valve (outwardly identical to original dual tank valves, but rated for higher pressure)
Corvette fuel regulator/filter
87 Tank switch inside the cab
Fuel pump relays and fuel pump/fuel tank switching valve wiring harness from an 87
Surge tank system above would be my second choice and both will work just fine. |
JC Whitney has the worst price for this valve. The Pollack # 42-159 Light Truck 6-Port Motor Driven Valve is well known. I pulled the data sheet for this valve:

Read application notes - not to exceed 65 PSI! They must have upgraded this design since the last time I have looked at it. The valves that I have used in the past stated not be used with systems over 30 PSI! Go figure!
