Not vapour lock? - how big/small are your lines?

Hi All

        More detail about fuel system. Pu has two tanks, no socks on
pickups. A fuel filter on each line to cross over valve. Then to low press
pump, which feed small storage tank - 1.5 qts. Thur another fuel filter into
high press pump, from there into high press fuel filter. Goes up to fuel
rail\press reg back to small tank. The tank also has return to tank via
crossover. The heat is coming from exhaust pipe about 12 inch away from
frame rail where all this is mounted. Problem occurs in hot temp in slow
traffic. Will finish heat shield made out of aluminum tomorrow. Hope this
helps. Have considered installing high press pump in both tanks, but most
electric cross over valves are only rated at 60 psi. 50 psi at engine is
probably 100 psi at pump. 

Thank for all the help
        Vance
