Dual tank with EFI and Pollack 42-308p
Anyone done the swap to this 65 psi valve? I'm looking at using the switch from an 87 as well since it's got a 4 pin connection as the Pollack switch but thought I'd ask if anyone else had done it already.

I am using the exact valve, but Standard brand, on my '77 which never was a dual-tank truck.

In an EFI application? What about stock 87 switch?

Re: Dual tank with EFI and Pollack 42-308p
Ah. Well.... I had my high pressure pump AFTER the switch.
EFI hose clamps should keep hoses on, but I don't know if the insides can handle 65 psi. Factory TBI is what, 13psi?? I thought all 87's are EFI?

Re: Dual tank with EFI and Pollack 42-308p
According to the specs sheet it's rated to 65 so should be good to go

Re: Dual tank with EFI and Pollack 42-308p
Polack 65 psi valves have a sticker on them stating the NEW 65 psi rating. If it doesnt mention it, Id be wary of it. All of the 65 psi valves I keep on hand have the correct label distinction. Parts store replacements dont have this rating.
