Fuel System Critique

Your filter placement confuses me. In my experience, it should be right after the pump on the feed side if the pump is in the tank.

Option #1 looks fine to me. I believe that is almost exactly how Aeromotive recomends you do it.

Same song. #1.

There you feel both rails at same end and out the other. Second options was big down side, if you run in to fuel delivery problems, your lambda show ok but you will melt your right bank pistons.

Only thing I'd chance is the nylon hoses to teflons one, they hold ethanol and E85.

My current project was #2 when came in but I'm chancing it to #1 with teflon hoses.

Sorry - my diagram isn't to scale. I had planned to install the 10 micron filter on the inside of the passenger frame rail just in front of the rear wheel; maybe 3 feet "downstream" of the in-tank pump (which has a 100 micron filter on the bottom of it, I believe).

I've been intrigued by the various threads/discussions about dead heading the fuel line out to the engine, but didn't know if it was something that could/should be done on this type of set-up; seems like I see discussion about it used on LS engines, but I haven't seen anyone use it on a big-cube BBC. Is there a reason or is the routing more of a personal preference issue?
