Fuel feed line

[Strikeking10]

I need some advice on fuel lines, I have a Lethal budget return system that reused the factory line, but I want to upgrade the feed line, I cant seem to find what fittings are needed to upgrade the budget system, What all is needed besides the line itself? Are rails needed or will stock rails really be okay?

You can run the factory fuel rails up towards 750rwhp on e85, give or take. You'll have to buy a AN fitting to factory rail adapter. Russell makes them.

Added fittings for a feed line is quite simple to figure out. You'll need 1 at the fuel hat, 2 for a inline fuel filter you'll need to add, and 2 for the fuel regulator. You should already have one fitting for the return line coming off the fuel regulator. I'll have to look, but you may need one straight fitting to go along with the fitting connecting to fuel rail.

This would be the time to install regulator in a dead head setup. Which basically is the regulator mounted before the fuel rails. Passenger side fender is a common spot.
