Kevin Schitoskey Posted February 5 Share Posted February 5 I'm in the final stretch with my FASS instal. I mounted it in engine bay to L of primary fuel filter. My question is this: I have all these fittings and some leftover 1/2" fuel hose. Can I replace the line going between my FASS and the secondary fuel filter with 1/2" fuel line? Will that be enough to feed an 8.3 ISC? I know the stock is slightly larger with 1/0 AN fittings. I appreciate the ease of putting a union on the original fuel lines by the now-unused lift pump, but the idea of replacing the 24 year old fuel line with new is quite tempting. FASS went great BTW; relay in the L rear bay electrical box by the other identical relays; trigger wire to front drivers side elec bay via 7 wire trailer wiring connecting the two boxes. Looks like stock. All lessons learned here and irv2. I really appreciate you folks. Link to comment Share on other sites More sharing options...
