255 lph non Walbro pumps.

[jmargo]

Anyone try the non walbro 255's like this ?

They claim to be same quality but quiet. Is the Walbro that noisy ?

Also there are two "kits" avail. One from Max PSI that is an install kit and relay and the TRM kit which appears to be a PnP with ridges and a machined filter adapter.

Who is running any of these. I also know I can just buy a generic install kit and go from there.

unless im looking to hear my walbro i dont hear it. Also when trouble shooting it helps to be able to hear the pump turn on/off as well. I realy dont think the noise level of the walbro makes a difference in our cars.

walbro isnt very noisy at all i would get the real deal, especially since even the real deal isn't that great!

My friend James is running one of those tre 255 pumps. works well and is silent. he has roughly 20K miles on it with no issues.
My walbro with 10K miles on it just died so im probally gonna switch over to one...once i get a new motor together:(

[etxxz]

been using their in-tank pump for two years. no problems to report. you can only hear it prime during startup. that's about it. my car is very quiet too, and i can't hear it still.

I do not think the real Walbro is loud. The TRE pumps are not high pressure. The relief valve opens too early to be ideal on an S50/52 running 51 psi base pressure and high boost levels. Compare the chart for a non HP Walbro and the HP Walbro and you will see the difference in flow at high fuel pressure. The TRE may still flow within your needs even at the reduced flow at 70 psi compared to a Walbro HP -- you would have to do the math to estimate your fuel needs. I would spend the extra $20 on the Walbro.

While a fancy install kit that costs almost as much as the pump is ideal, it is not necessary. You can buy thicker sleeves from APE (you want the middle size thickness of the three available) that will make the Walbro snug in the BMW hanger with a hose clamp for added security.

For what it is, the Walbro is louder than it should be. I likely have a louder car than most of you, and can still easily hear it over the engine (Although the fuel pump sits right between the two occupants with minimal noise shielding).

I used to think it was worth it for the bulletproof durability, but I'm seeing more and more early failures every day. That, and the Walbro is very temperamental with high gas temperatures. Because of the poor design of the Fiero fuel tank, returned fuel from the rail is dumped right beside the pump intake. Thus at low throttle levels, the pump essentially circulates the same fuel over and over, pumping very little "new" fuel. Well the fuel rail is naturally hot, and the fuel heats up as it gets closer to the engine, runs through the rail, then returns, probably gaining a hundred degrees or so. Well recently, a lot of us have noticed failures of the pump after extended drives at low throttle (Mine happened on the highway, 80mph, after about an hour). Then the car won't stay running, the pump sounds godawful, and it takes an extended period of time for the pump to cool down (Mine took over 2 hours).

Now, this isn't the Walbro's "fault" directly, it is a design flaw in the system, but the stock or other OEM fuel pumps have never had this issue, and its happened a number of times with the Walbro. Next time mine goes out, I'm swapping to a C6Z06 fuel pump on my Fiero. Most fuel pumps are universal, and the C6 kit drops right into the Fiero, flows enough fuel for my needs, is dead silent, reliable to 200,000 miles at least, and won't die after an hour on the highway.

I switched from a Walbro to a Bosch due to reliability issues.

Does that drop in also ?

[Neil]

Yes. IIRC, it was Bosch 044 (or something similar). More money than the Walbro, but a fuel pump failure at the track is a real drag!

This.

The 040 is the intank pump, the 044 is the external pump.

IIRC the 040 is the equal to the 255 - but it can flow a touch more at the higher pressures.
If your getting close to the limits of the 255 - grab a 044 (they are louder) and a stock pump.

Throw the stock pump in the tank, the 044 inline (with a relay and wiring) and you wont have fuel issues :)

[someguy2800]

I had one of those that I bought from another member that claimed it was a walbro. It failed in three months and was loud as hell even inside a full tank of gas. I could hear the pump quite clearly while driving down the road. After it failed I switched to a real walbro mounted outside the tank and it is much much quieter even being outside the tank. Its quieter than the stock bosch pump was.

Question: Is there any reason that I can't run the 255 in-tank (like I have it now) and then tack on an 044 inline for both more fuel piece of mind? Essentially the 255 becomes a primer pump and the 044 insurance - I'm thinking....

Its very common to have a intake pump feed a larger inline pump. In my opinion, you would want a low pressure high volume pump feeding a high pressure pump. For fueling needs Id email Sales@MaximumPSI.com. Mike has done countless fuel setups for all different style cars. Daily, drag, circut, etc. Also a Bosch 044 is good for 700hp with proper lines and rail.

[boosted 528]

Does anybody have pics of a bosch inline 044 mounted on there car?

[gnarfy]

What does TT stage 2 use ? I tough it was Bosh 255

if it is, I didn't notice any difference from oem to the one that came with the kit...

[qscftz]

I would also highly reccomend using a bosch pump instead of the walbro. I flow tested a genui walbro 255l pump against a 20year old E30 stock pump and a 044 Bosch pump. The 044 is head an shoulders above the walbro and stock pump. Disapointingly the walbro was only about equal to the dead old stock pump. The 044 offers also by far the highest fuel pressure, which is important for forced induction.

on my turbo 325e, i used a tre 255 in tank pump and deleted the inline pump and it worked like a champ all the way to 300+ lbs of torque

[BadBoostedBmwM3]

Op, a guy on e46F.com "bluejeansonfire" bought this pump for his e46 non-m and it went out in like 2 weeks. They replaced it free of charge, but Im sure he wishes he bought a walbro instead.

[clintjg]

Got it. I'm only running the walbro 255 in-tank now to 500+ wheel. If I take it any further I don't want to rely solely on the walbro so I think the 044 is the best bet but leaving the 255 in the tank is kinda what I'm thinking.

I'm running - 633cc injectors now but anticipate jumping to the ID1000's once I'm standalone.

[dcvee]

I dunno...once again I come up perplexed:help. I've used a dozen or so Walbro 255lph HP's and I've never had an issue. Also, the GPH are almost identical at 72.5psi between the 255lph HP and the Bosch 044. Either supporting 650bhp applications.

sorry, TT use Walbro 255lph...

Anyone know what Rukman is running in the TT Stg3+ ? I'm looking for it to support over 700hp.

I would think a walbro 255....

That seems to be all that the walbro website is giving me.

I know i have seen flow charts for these pumps, but it looks like the manufacturer isnt listing them on the website.
