First, as usual, RJ, that thing is amazing. I am just about to plump fuel line to my 5.7... Your lines make me jealous. What fittings are you using to go steel line to AN?
Second, that reg/filter is regulater @ 58 if I remember correctly, and several guys here have run them without issues. To the OP with the fuel reg question, there is a "feeding the hemi with fuel" thread in the hemi swap section that cover this a bunch...
Once again, Your car is looking amazing... Thanks for the pics...
