Concerning fuel pumps I'd go for quality and proven reliability. Weldon
seems very good - however, which pumps one should be thinking of? They have
the aerospace line of pumps (15-40 psi, 25-45 GPH - this seems way more than
enough for an IO360) mechanically driven by a separate electric motor, and
added bonus is that they contain a relief valve. Weldon also has the
automotive 500-A flow thru with its self contained motor but which needs an
external regulator (60 psi, 60 GPH - For an IO-360 this second pump seems to
be overkill).

Within the context of an RV8 with an IO360, my understanding is that I
basically need an electric boost pump for starting and for ensuring
satisfactory fuel pressure during takeoff. Am I correct? If so, this
precludes a continuous duty pump.

As for Air Flow Performance - they have a pretty flash based web site but
terrible in that they offer no info nor pricing on their products - it is
near useless and one must dish out 25+ dollars to get their paper catalog
for more info - it is really a pay to see scenario.

My question to listers are: 
Boost or continuous duty?
Which Weldon?
What about AFP?

One last question: are IO360s normally supplied with their own mechanical
pumps and if so, at what RPM will they self prime if at all?

Thanks all
