RiffRaff Fuel Rail Crossover

Anyone out there in 6.0 land running one of these. It claims to be a regulated return, but how is that possible without a...um....regulator?

Yes, looks to be similar to the 7.3 FRx which allows a metered return path for the air entrained fuel and purging it from the heads back to the tank using the stock return.

I would definitely shield those lines from the up pipe exhaust heat in heat shield tubing just to be safe.

Isn't it normal for a regulated return system to have lines coming off the back of the heads? Your post kinda sounds like you're talking about a new concept.

The last one I installed came with shielding already preinstalled on the lines. Seemed well protected to me.

I am sure it is partly OCD for me, but the Riff Raff lines seems like standard unshielded fuel line.

Not a new concept just added protection (chafing and heat exposure).

Those lines are vulnerable in my opinion which is why I wrapped mine.
