For the price of the Walbro, its hard to find anything better but if you're willing to pay the POWER ones from Japan rated at 210 l/hr and 255/hr is quiet but then again almost twice the price.. or alternatively the SARD ones which look more like a Nippondenso one..
I like the whine, it sort of give you the race car feeling... All my cars have a Walbro on them..

The pump drops into the tank but you'll have to scale your injectors or buy an adjustable FPR. At least in my experience. I have no idea how other pumps will affect FP.
does adding a fuel pump require larger (650) injectors to handle the additional fuel pressure? from the sounds of it, the answer seems like yes (or a fuel pressure regulator).

Also, for what it's worth, from what I've read, it's okay to run most fuel injectors up to 4 bar (58 psi) of fuel pressure and not have issues as long as you scale your fuel maps to compensate. This allows you to stretch out the useful life of a set of injectors. For example, stock 550s would flow 635cc/min at 58psi, a 15% increase in fuel flow.

thanks for the info propellorhead! very informative.
I am assuming that the increase in fuel pressure will also increase the regularity to clean/change your injectors if you're still running stock (525cc)?
In my situation I was planning on installing a fuel pump and then getting my S-AFC2 accordingly...

Stockers are 550s or 560s depending on who you talk to.
I don't think running more fuel flow or pressure doesn't mean you need to clean your injectors more often. Dirty fuel does though.

I do remember hearing something about this voltage stuff somewhere with the EVO's fuel pump. Either way, I think Ill end up getting a Walboro and if something better comes out, Ill just get that! IF the Walboro is indeed too noisey.

Mine is quiet also. But heat that thing up with a long drive/hard driving with 1/4 tank of gas and we are talking loud. But I am all about Function over Form. If it works it works who cares if it's $90. Actually Al told me mine was one of the loudest he has ever heard. Then again I drove an hour and 30min to the tune then 2 hours of tuning the pump was whistling rather loudly. Got it home let it cool down for 4 hours started it up and no sound. It all depends on how hard you work them.

Power used to be a Denso pump. But they confirm that their pump is manufactured by an alternate firm. That said it is copy of the Denso and looks identical in all respects. The issue in my mind is that it represents an unknown quantity.
Where have you seen the SARD pump?

I suppose it could. I figure there's two issues involved. One, less fuel means the pump will heat up, perhaps vibrating differently in the pump carrier. Two, less fuel mean less sound dampening.
FWIW, EVERY VW I have ever owned made noise when the fuel level dropped below a quarter of a tank.
Man, I wonder what one of these "loud" pumps sounds like. Mine is so damn quiet that I forget it's there. Only when I drop down to an 1/8 of tank do I even remotely hear the pump. Weird.
