it's not hard at all.
yes you can boost to an equivalent of 19lb/hr@43.5 psi (will be less on the YJ rail but as a comparison with the ones you have now) and even more than that (i had my pump running at close to 50 psi)
option 1:
you can use the hesco adjustable FPR $179 directly from hesco
http://www.hesco.us/shop.asp?action=details&inventoryID=43022&catId=7973 (this is a special, always saw this at $190 on their site)
option 2:
or you can use this
http://www.summitracing.com/parts/MAA-4305M/ it's $99 but you need some adapters, fuel line hookups, a fuel rail plug and a braided fuel hose from the fuel rail to the FPR
the fuel hose can be this one
http://www.summitracing.com/parts/RUS-658200/ which is at about $20 but will go to even $30 if you want a longer one
the fuel line adapters you can make yourself using an old fuel rail, the plug is easy to make. the fitting adapters for the fuel and return you can buy at any autoparts store locally (don't have the p/n for those but i can look it up)
the advantage with this one is that you really get a top of the line FPR which is serviceable and made out of billet aluminum - also it has a port for a pressure gauge which is great for tuning (if you use the hesco you still need an adapter to fit a pressure gauge on the schraeder valve).
the pressure gauge is best at 0-60psi range, something like this
http://www.summitracing.com/parts/SUM-800160/ the total will take you to about $140 without the gauge and to about $155 with the gauge (you can get them cheaper off ebay, 0-100 psi will also work but it's harder to get to the 1psi adjustment).
EDIT: the plug for replacing the FPR is available from Hesco as well for $25, but it's easy to make either from aluminum bar or an old FPR, i find the $25 to be a bit much for that.
