Should I replace OEM Intank + Airtex Inline -with- Walbro 255HP Intank?
Sorry, I know there are other topics that discuss this subject but I couldn't really find a specific answer for my application.
I have a 96 Integra GS-R, I'm running a custom Drag III turbo kit, with stock injectors (240cc) and the Airtex inline pump. Should I replace OEM Intank + Airtex Inline -with- Walbro 255HP Intank to run 8 - 10psi of boost? First, will it provide the necerssary pressures safely? Secondly, will I see any advantages by using this setup (walbro intank) VS my original (oem intank+inline)? I'm planning to go AEM EMS in the near future too, btw.
Thanks,
Sharky

I don't like inline pumps.
If your going stand-alone in the future go with a high volume fuel pump and not a high pressure pump.

Yes I would def get rid of the airtex pump and go with a Walbro 255. I have seen the airtex go bad soo soo many times

because u r running stock injectors w/ a very high rise rate FMU the inline fuel pump is REQUIRED in order to support the high fuel pressures on boost that the fmu creates. intank fuel pumps flow alot of volume but cannot support pressures above 100psi. if u r going standalone u won't be running high pressures anymore and u can get rid of the inline @ that point, but until then the inline is nessacary.

DIRep, but it's not the regular pump, it's the high pressure one. I though it could support it a little beter? I checked out: http://www.autoperformanceengineerin.../fuelpump.html
Do I look at the Flow rates of Galons/Hr or the Amps? What what does the Inline produce VS what the intank can do?
Thanks!

yes, but the high pressure intank can still only support up to 100psi of pressure. With an FMU and 8-10psi u r @ 120-140psi of fuel pressure.
if u look @ the flow rates, they get less and less as the pressure increases. the high pressure pump can support about 90psi fuel pressure safely and the regular one can do 70psi. 120psi pressure, like u will be running, is not even on the graph.
