   You mean Pegasus Auto Racing?

   http://www.pegasusautoracing.com/

   Pegasus.com is a sailboat racing team, apparently.

PegasusAutoRacing.com is the website for the auto parts. Silicone hose
elbow 45 1 1/2" id-$28.99.


Another question- about the correct type of anti-freeze/coolant
additive- is there a preferred anti-freeze for the 13B?

Not too bad for silicone hose. Usually a dollar an inch.

All I know  it is 50 50
