FWIW Walbros have a very good reputation in the Japanese car community and are common drop in replacements when the stock fuel pump doesn't deliver adequate flow to support higher HP applications, which commonly occurs when boosting an NA engine or significantly increasing the boost on a turbo engine.

I've run Walbro 255 lph pumps in my '88 300ZX Turbo and my previous 240SX turbo for many years with no issue. They make good pumps.

I agree here. I had a Walbro 255 LPH in my turbo eclipse for 2 years and it never had a problem. Which is why I wanted to open it up for discussion. I know they are a pretty good manufacture but don't know of any pros/cons to using them in a Porsche.

Well I would think something that can deliver an adequate flow and good pressure with 12V of power most likely doesn't care if its sitting in a Porsche, DSM, or Nissan. Two terminals and a fuel hose connection seem pretty universal.

I had a spare 255 I gave an E30 3 series BMW friend of mine a while back. It had been sitting in my garage for years when I thought my Walbro was going bad (turned out to just be a fuel pump relay). Anyway he did some searching and they seem to be pretty commonly used in the BMW world as well.

This is a great forum with many knowledgible people, but there are a lot of dyed inthe wool advocates of OEM stuff. Sometimes it is justified when you can end up with cheap Chinese crap, but sometime the aftermarket provides a good affordable sollution.

You may want to check in the 944 forum too. There seems to be a broader user of non-OEM stuff partly becasue it costs less, but also because they deal a lot with forced induction which seems to find the flaws in any car and requires aftermarket sollutions.

Fuel pumps are mostly all the same in the way they move fluids. It's really just the sealing of the armature with bushings that matters IMO, because that's the point where a fuel pump will fail and leak residual pressure, which can cause the common hot start issue of fuel boiling due to residual pressure loss. Put it this way, IMO there's no big secrets to fuel pump design, it's just like a tapered roller bearing, a bearing is a bearing is a bearing, no big secret to design.

First- I agree walbro is a solid go-to supplier for many other platforms, flow well, easy to upgarde if a bit noisy in some applications.

That said, a look into the spec sheets for the several bosch fuel pumps can show different pressure and flow rates. Sounds like your is fairly standard given the part # quotes, though.

Very good to see some more pay it forward activity on here! Worthwhile simply for the O/Ps sig quote, in my book.

Thank you. I don't remember when or where I heard it but this is one of the few quotes that I can recall at any given time. When I heard it, it really struck me and made me think. I have it as my sig and status on just about everything I am on. I remember finding out who originally said it but I can't recall it atm. But I'm sure a quick google search would turn it up.

I mentioned this in your other thread, but thought it might be useful to document it here as well. I put a Walbro on my '79. Mechanical fit was very good and flow was 2x over the minimum in the WSM test.

yup...got a Walbro NIB in my attic. Make me an offer. IF not i will use it as a fountain pump in my pool

I chose the 044 in the end...its "kraut"

Thanks to NoVector I now have a fuel pump waiting for me at home! Thank you kind sir. I am now waiting on parts from Roger that should be here in the next day or 2. Then I'm just hoping for some nice weather this weekend to get the car all buttoned up and check fuel pressure/leaks.
