Incorrect.
If you take a quick review of the walbro's ability to handle fuel pressures at or above 100 psi, you quickly notice that it comes up dangerously short. http://www.vfaq.com/mods/Walbro-specs.html As you probably know, if you run boost higher than 6 psi, your fuel pump is required to push fuel at ~110 psi or so. Looking at the below diagram, following the walbro 255 lph-HP model's pressure pushing ability (red line), you can understand at that high of a pressure, the walbro can no longer deliver substanital amounts of fuel. Hence, the need for combination intank and inline fuel pumps. 15 gallons per hour is NOT enough.

well all i got w/ mine was an msd inline, i think it goes 43gal/hr @ 40psi if i remember correctly, thats rite in the middle of the stock and warblo setups, that sucks. i'll be ordering a 255 soon to say the least.

Bryan,
I don't claim to know how much pressure is provided at ~110psi with the inline pump and stock pump that you have in your setup. With the fuel pump you referred to, that MIGHT be enough fuel pump pressure needed when working in concert with a stock fuel pump. I don't know. You may want to find out the specs on the HRC inline fuel pump.
