walbro "255" fuel pumps / 044

[avants2turbo]

Cn anyone tell me if these are any good, they are 255lph and look like a direct fit it the existing aby fuel basket?

Also are there different 044 pumps ie. Internal or external mounted ect. Only PN. I could find is 0580 254 044

Is the 044 200lph?

They aren't as good as 044 pumps, Faheemo had one car was leaning out, changed to 044 was fine, reported cases like this from a lot of places however depends on your bhp target up to 400 bhp I dont see a problem with them.

The walbro isn't direct fit in the UrS4 fuel basket, don't know if the ABY basket is different..? The walbro is smaller than the stock pump so you have to put something that holds it put in the basket. I put the walbro inside the stock pumps housing. Had to destroy the stock pump of course... It's good for 400hp, and if you are lucky maybe for 500hp. If you want to be sure, buy a 044.

I am using a replica of the Walbro 255lph...
Well, actually it's better than the real thing - it's a NipponDenso pump.

These hold to 450-460hp when relayed.
The advantage in front of the 044 pump is that is not as noisy.
However, the 044 pump can go way more than 450-460hp. So it depends on your power target.

So a viable option for rs2 spec?

Yes, this one:

The guy has 1342 feedback, 100% positive from selling these pumps.
Be aware though, since it's thinner than the stock pump (just like the walbro one), installation is not plug and play.
The wiring harness was different on mine as well.

Luckily you get the connectors with the pump. I cut off the old Audi connectors and soldered on the ones provided.

Cool, thanks. One more item crossed off the list

You are welcome.
I am running this thing for half a year or something now - no issues, and it's silent.

prj: What is the diameter of this pump and how did you fit it in your C4 UrS 43 mm diameter basket?

I don't remember the exact diameter.
I wrapped some old rubber hose around it and soldered on the connector provided.
With the hose wrapped around it fit very firmly.

Not really the perfect way to do it, but it is very securely mounted.
Thuppu provided an alternative - destroy the original pump.

I hope the rubber is compatible with gasoline and does not become a oozy black goo.

Yes, it is compatible.

Here is a chart of two Walbro's measured in parallel:

Just fitted my Walbro 255, damn, what a difference! No hessitation, more responsive and a peice of **** to install, the aby wiring plugs directly to the pump, no mods! Awsome pump for very little money!

If the ABY wiring "plugs" directly into the Walbro, I suspect the pump you replaced was no the original ring-terminal VDO but an aftermarket Bosch (with a plug)
