Wow, looks like you guys pretty much have it covered.
We used a super duty pump, Aeromotive reg from summit, and pretty much just customized from there.
Had fuel lines made at the local IH dealer and used fittings from there and industrial supply in town.
We used a base with Boss O ring fittings into it and it will accept a Baldwin 1212 spin on filter/seperator or equivalant, filter is only about 8 bucks.
You can also use "Earl's Y block" a splitter available from Summit.
Tom S built a really nice system using a SD pump and a Standyne FM100 prepump.
Stanadyne's "Fuel Manager" FM100 or FM1000 are nice units with a built in heater and thermostat and accept a spin on type filter. Tom modded his to accept a Cat filter seperator and is running a 150mic prepump, and a 2 post I believe.
What I plan to do with mine is, Stock pump with lifter "helper" pump, or two SD pumps if I need it, probably not with my injectors though. A Stanadyne or Dahl (really nice too, can get heated version, and comes with the clear bowl on bottom) pre pump unit. And a simple spin on for the main filter, probably 2 micron. That with aeroquip hoses, y block, fittings, and Aeromotive reg from Summit should do the trick.
