This is the odds'n end forum so.

Anyone know of an external fuel pump rated > 5gph @ 30-50psi and ~$50 ?  I found an MSD external fuel pump but I'm hoping I can do better than $100 for an efi fuel pump.   < http://www.atlanticspeed.com/productcart/pc/viewPrd.asp?idproduct=2735&idcategory=0 >

And if you were curious, I did some calculations and found out that if the GS500 was 100% air efficient at 11,000rpm and WOT the engine would consume ~3.4 gallons an hour.  (theoretical maximum fuel flow for the GS engine).
