What would be quieter, the Walbro 255 with the Hahn inline pump or just the Walbro 255 itself?

Siueclipse said bigger injectors would solve the noisy pump but right now I don't really have enough to get some upgraded ones. haha.

The walbro pump is much quieter then the hrc inline. Both together would be hell. I ran just the walbro and it worked just fine.

noisy as hell
but on the plus side everytime someone gets into my car i get to explain what the noise is

WTF?????? thats the biggest load i have heard yet!

I cant remember who but one member took and wrapped the walbro with a sound deadening foam and zip tied it before he installed it...claimed it worked really well.

Actually, running larger injectors, means you have to run lower fuel pressure(SFMU setups anyway),and lower pressure on that inline, makes it whine even louder..The walboro is a great pump, and i can barely even hear it when its on. It doesnt flow as much as the accell one does at HIGH pressures, but it alone using a sfmu setup, should be good for a decent amount of boost, running larger than stock injectors anyway. I wouldnt run the intake walboro more than 80 psi or so..so whichever injectors you run, and how much boost you run, to get that pressure, that would be the safe limit i would say. The intank walboro flows really well at lower, sane fuel pressurs.
