I choose a Bosch high performance pump (part # 580 254 044) that Truchoice
sells,,, its specs are160-220 LPH @ 5 Bar output. It is an external pump.
According to the fuel system experts at Mectronics(?sp) on Long Island
(recommended by Bosch & Truechoice) this pump is used on up to 700 HP Indy
cars, so its a bit of overkill for a 215HP S14, but they said its a great
fuel pump. They do offer some pumps with less output, for a bit less money,
but the price was close I just got the top one.

My 2nd choice was a Mallory Fuel injection pump, available from Summit Racing
,,, whose specs & price closely matched the Bosch,,, but I went with Bosch on
reputation and the recommendation of the guys at Mectronics.
I have heard of people using "in cell" pumps on fuel cell installs, but
decided to go with a single external pump first. The guys at ATL said that is
the much more common setup. The guys at Mechtronics said the single "044"
pump would work very well,,, as long as it can be mounted lower than the cell
itself, which should be no problem.
