Ahhh, I thought you were talking about glass bowl actually built into/onto the pump, not screwed into the outlet. The "twin tower" pump you describe is standard-issue slant-6 item. Should be easy to hook up on inlet side with (new) flex hose to frame hardline, and yeah, just do the fuel line mod to replace that dangerous glass-bowl filter and avoid difficult hardline match-up problem.
Buy a good brand (Carter) fuel pump; it's getting harder and harder to guarantee the new pump won't fail without warning. Finest "permanent normal trading relations" quality, you betchya.
