I am hoping you guys can help me because I am really confused. I have a Miata powered Locost 7 based on a 2002 1.8 Miata (return less injection). The car has a hot start issue, it runs well, if I switch it off it re-starts fine. If I switch it all and wait 5 mins it will not restart until it cools down, say 20 mins. I got the car built so I do not understand why the fuel system is plumbed the way it is. But to me it looks totally wrong. To me it looks like the feed line goes to the fuel surge unit, the return line goes to the evaporator canister, and the vent line is just vented to the atmosphere. I am not sure I have a fuel pressure regulator at all.
The first picture is of the tank http://s562.photobucket.com/albums/ss63/fastgxc/?action=view¤t=2012-03-24115835.jpg The hose at 2 o'clock goes to the evaporation canister. 4 o'clock is the fuel feed. 9 o'clock in a vent line, just vented to atmosphere. Picture 2 is the evaporation canister were the 2 o'clock hose goes. http://s562.photobucket.com/albums/ss63/fastgxc/?action=view¤t=2012-03-24115905.jpg Picture 3 is the surge unit.were the 4 o'clock hose goes http://s562.photobucket.com/albums/ss63/fastgxc/?action=view¤t=2012-03-24115921.jpg So I am thinking that I don't actually have a fuel pressure regulator at all. I am looking for a plan of action to work all this out. What do you think? Graham
