You can forget the FSV and go with a 38 Gallon rear tank.
Run the fuel supply straight to the engine, and return straight
back to the tank.
Since you are going to deep 6 the Cruise Control and the factory
water separtor. Install one of these Racor 500FG Fuel/Water separators in that corner. I installed one there several years ago.
You can use a 2, 10 or 30 micron filter inside it.
I use a 2 micron filter, I figure you cannot have too clean of fuel.
I also have the Factory spin-on Filter.
There are a ton the chicom knockoffs on the market for $40+ or so. I would go with the real deal made in the U.S.A.
You are right, these engine will burn what ever you want to dump into the fuel tank. I burn just Diesel. My engine isn`t a garbage Disposal.
I also run a 130A Alternator, but a one wire one and my one V Belt seems to work ok.
I also recommend a Vacuum Gauge to keep an eye on it. Loose vacuum = no Brakes.
The Hydro Boost is a better way to go for better braking.
I lost my Power Steering last August. Suddenly it was not there.
Wonder how that would effect the Brakes? Probably same as no Vacuum I would guess.
I should add here, I still had steering, just lost the power assist part of it.
But I have lost my Vacuum more in the 10 years I have owned this thing. Usually the Boosters causing the problem with me.
I changed the Vac Pump one time, and the Lift Pump one time in the 169K mile I`ve driven it.
