Chris,

A pin hole at that point might be meant to let = any vapor=20 escape and route back to the return line rather than the main fuel = return. =20 A pin hole will certainly not flow back very much liquid fuel. At = idle=20 most of the fuel would normally be returned, at WOT much less of the = fuel will=20 be returned. However, this should not stopped the engine from=20 firing.

I=20 was wondering about the fuel return too, not as to why we are not = getting a=20 start, but more in general since the Mistral intake has a pin hole at = the end=20 of the fuel rail as it enters the return hose.

The=20 return line is the same size as the inlet lines.....fitted for a AN 6=20 connection (can't think what makes the hose)

Have you tried the injector simulation test to see if the = injectors are=20 working?

As for=20 fuel pressure, what size is your fuel return line to the = tanks? Most=20 people get a couple psi increase with the second pump. To get = as much=20 as you have, I'm thinking the fuel return can't flow enough to = return the=20 volume from both pumps at once. This isn't necessarily = something that=20 has to be fixed though.

Good=20 luck,
