maybe I'm just inclined to 'do my own thing' sometimes... but I'm thinking about putting a Bendix pressure carb (i.e. PS-5) onto an o-320 or o-360.
Pros:
Less prone to carb ice
Less expensive than a full FI conversion
Independent of electrical system (except for boost pump - but still have mechanical engine driven pump)
Works inverted
So, some questions... would a cold air sump be appropriate / advisable?
Electric boost pumps for more than carb pressures are horrible expensive. Which is crazy when automotive FI pumps put out much more pressure...
How about this for a boost pump (spec for PS-5 seems to be 14 psi)

Would it make sense to plumb the two pumps in parallel? [with check valves?] That would seem to be more reliable in case some pump became clogged.
Thoughts anyone?
