some bosch high psi/high vol. pump info

[Ross Corrigan]

rare day when I can contribute:)

I figured this info may be of use for others looking to purchase a fuel 
pump.  I have the tables (some 7-9 pages) of fuel pump info from a member 
here previously but coudn't cross over those PN's with anyone and the OE 
application wasn't always specific so I chased down some Bosch PN/info.
BOSCH TECH US/CANADA 1-800-521-5462

I called Bosch and got the psi/gph and PN info below and then pricing is 
CD$'s (/1.55 ~ for US) from a local auto chain

43.5 psi at 58 gph  0580 254 909 $210 my cost but not in stock
72.5 psi 47.5 gph  0580 464 070  $269 my cost, $369 retail
72.5 psi 42 gph     0580 254 910  $227 in stock and $303 retail
72.5 psi 33 gph     0580 254 911      didn't ask for $ info
58 psi at 36.5 gph 0580 464 069      didn't ask for $ info
-all 12mm threads

My setup won't exceed 450 flywheel hp so I figure using ~.55lbs/hp/hr 
=247.5lb fuel/hr. And I forgot to ask Bosch if their gallons were US or 
Imperial.....either 6 lb/gal or 7.2 which yields a possible bracket of 41 
or 34 gph.  As all of this is somewhat conservative using .55 (correct? 
depending on AFR etc) the 72.5 psi/42gph  $227CD pump should be fine 
right??  My edelbrock proflo 3500 specs 45-50psi.  I'm optimistic this pump 
will be quiet as well.  One friend reccomended wrapping it in tape to keep 
it quiet and prevent rusting.  Any comments/ideers on this?
