Here's the deal - Whenever the truck is cooled off, it starts hard - like it's not getting fuel. I whirl it over for 5 -10 seconds before it will start. After it is warmed up, it starts fine. I was told it could be a check valve? I know there is a rubber hose on the top end of the engine (a vaccum hose?) that blew off making a hissing noise. the other end connects down almost underneath the battery on a T type connector. I believe the hose is 1/4" in diameter (inside) and about 15" long. I put a another hose on but i had a really hard time getting it over the fittings - maybe it's leaking air? Any advice would be appreciated. Maybe I will get pics.
