This is the regulator that I used:
Mallory 4307M - Mallory Universal Fuel Pressure Regulators for Fuel Injection - Overview - SummitRacing.com
I'd say it's not an issue if it's rated for gasoline/alky. Also, here is a list of everything I ordered from Vulcan (quantity first, rice second). Note, this does not include the pump, the fuel hose, clamps, and a few other little odds and ends I used but you get the idea and see what fittings are needed to tie into the fuel system.
M1406 14mm metric to 08 MJIC adapter 1 7.49
FFVPU Filter to injection hose kit 1 33.99
DSI DrawStraw I 1 44.99
