Here is a problem a club member is experiencing with a recently purchased
TR6 that came with SUs. I told him that vapor lock comes up once or twice a
year, but just doesn't seem to amount to anything, at least no vapor lock.
The only thing is the SU conversion on the 6. I'll share the list's
thoughts with him. Thanks.

I have installed the Moss HS6 SU conversion in my 1970 TR6. I can start the
car, but when it gets hot, the car stalls and cannot be started until it
cools. When the car begins to stall, the rear SU blows fuel out of the vent
tube. I have all metal plumbing from the fuel pump to the front of the
carbs ... the fuel line splits below the front carb and then feeds both
float bowls. The problem appears to be vapor lock, but does anyone have any
thoughts as to why this is happening? Could the metal fuel lines have
anything to do with it? Would a heat shield cure this problem?
