Stop...you guys are scaring me! What I don’t know won’t hurt me, right?

Now...back to that steering column adjustment on the Spitfire...

The line from the engine bay to the fuel pressure gauge has the ethylene glycol.  If you have a rupture in the line in the passenger compartment you just get a wet leg, not a ball of fire.

Much more than that and I start to transfer aluminum from the piston to the cylinder walls.  I think there's some variation in temp readings between different probes and gauges, I don't know what the accuracy really is.
> It's a great troubleshooting tool when the car starts to run like crap.  Another helpful tools is a fuel pressure gauge (with isolator so you don't pipe gas into the passenger compartment).  Pressure too high overruns the floats.  To low and you've got something funny with the feed like a regulator / pump going bad or you forgot to put gas in the car.
