I checked the fuel pressure as it leave the tank, it's 75psi will a
running engine. I have not been able to re-create the hot start
issue, the car is still up on saw horses, but I should have it back
on the ground next weekend. I was kinda hoping that the fuel pressure
would be low as it would give me something to fix. What would be your
best guess?

I would plumb one inline on the hose going to the fuel rail.
First determine if your tank is venting by checking gas cap.
I would release the pressure and see if it starts. Is it
under pressure or vacuum?

I am not sure that I have any FPR at all. I can see
nothing in the tank apart from the pump. It should be
running again this week. What is the simplest way to get
a fuel pressure gauge into the fuel line?

Have you checked fuel pressure under the running, hot
and not so hot conditions?
The NB has a returnless system, the FPR
is essentially on the fuel pump end. The dampener is
supposed to accommodate pulsations, but does not
control pressure.
What if you loosen gas cap? does it suck or blow
under this condition?

More likely it's an nb pulse damper, which is the
same footprint.

a stock Miata Fuel Pressure Regulator to me...

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.

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?
