Sorry, I missed this part. Here's a table on frybrid's website. I don't know how current it is, you may have to double check the facts about greasecar, but the frybrid stuff hasn't changed.
http://www.frybrid.com/kittest.htm

In a nutshell, with frybrid you get aluminum tubing fuel lines inside a 3/4" heater hose for hose-in-hose (HIH) heated supply and return fuel lines. Greasecar has a HIH setup, but uses PEX tubing instead of aluminum. Also, there's only one line coming from the tank, so when you purge, the fuel is pushed back through the VO filter. And the return is always looped, so if you get an air leak, theres no way to purge the air out of the loop (while running on VO). Frybrid has a full return setup so any air in the system gets pushed back to the tank. Adding a third valve to frybrids setup allows you to loop the return when running normally (keeps fuel hot, eases load on filter) and can switch to return to tank for purging.

The heated pickup in the tank is copper in greasecar, aluminum in frybrid. The greasecar pickup uses compression fittings to keep the coolant from leaking into the tank. Frybrid has all welded fittings.

Frybrid has automatic operation, based on coolant temperature. Greasecar is manual operation (3-way toggle switch) and you switch when the car is warmed up. You can upgrade greasecar to the co-pilot.

Frybrid includes a FPHE.

I think that's about it. Both are good kits. One uses better materials for working with VO, but, of course, is more expensive.
