Paul-

Silly question: Do I apply RTV between the engine and the exhaust
manifold while installing it?  If not RTV, then what?

Also, gascolator on pressurized side, or non-pressurized side?

Thanks,

I used the stock gaskets on my 20B, and have small leak on #3 after only a
few hours.  I'm told that RTV works very well. Also plain old GE silicone
sealant is said to never fail.  Just put about 1/16" thick strip out a ways
from the port where the metal stays cooler, let it set up just a bit before
bolting on the flange.

I haven't taken mine off yet to repair, but if the gasket is in good shape,
I'll probably put some RTV on both sides and torque it back up.

Best to have some sort of water and sediment trap, and maybe a not-so-fine
screen, upstream from the pump, but do the filtering downstream.  Any
potential pressure drop upstream from the pump increases the potential for
vapor lock.  Make sure you use a filter rated for FI pressures.

I am dumb founded. I would have thought the temperature is
a lot higher than 500 F which is what RTV is supposed to be good for.
