Thanks for the response I really need to get this motor fired and everytime i walk by it sitting on the pallet i am thinking man i need to get these parts ordered...

so just to confirm.. with the single fuel rail on my lm7 this is the way to go? (i dont see a regulator on the rails anywhere) ..

i am thinking i need
a 640850 for the fuel rail (rail inlet)
a 640850 for the corvette filter (fuel inlet)
a 640860 for the corvette filter (fuel return)

some other fitting for the corvette filter outlet to the fuel rail host

and of course some combo of fittings at the tank (once i figure out which tank to use)

am i close?
