I swapped from vacuum to hydro-boost and at the same time did away with the RWAL system and installed a Wilwood adjustable proportioning valve
I like the fact that the 83 had 2 spin on fuel filters instead of the crappy square box filter or the 6.5TD fuel manager drop in style on the intake
As for me I think having filters in awkward and hard to reach places is just dumb, so I made a bracket and relocated the secondary filter from the 83 to the firewall instead of the intake, the primary / water separator will be in the bed (no more fuel baths when changing filters !!!!)
I will also be modifying / bending up some new fuel lines and run them down the passenger side frame rail instead of the drivers side like factory
I have moved my fuel tank from under the bed to in the bed, this is ugly and I don't like it, but it's only temporary till I get a big aluminum semi tank
And the money shot
