All of these 3 port universal solenoids I have found have been for 5/16 hose. I found one from Summit that was listed as 3/8, but when I got it, it was also 5/16. I had to go to a 6 port, then just capped off the unused ports.
Is this for a duel tank truck? I've thought about going to two tanks. Classic Trucks and NPD has the tanks and fuel lines and all that but it still looks like a pain to install. And now ya'll are saying the three port valve isn't available? I have a fuel tank with three hoses on top and I can get the same for the other tank. There are some that are four hose tanks and I think they may be for the two tank set up but I'd have to study it some more.
So where else can the three hose valves be found? By any chance does Chevrolet still have duel tank trucks and may offer this valve for them? Or have they gone super complicated like everything else with vehicles these days, all computerized?
