So I will eventually be doing my own inline fuel pump upgrade. Unlike the other options I've seen with a cheap Walbro and worm style hose clamps, I plan to take a more professional, engineering approach. The pump will most likely be a Bosch FP 200, commonly known as 0 580 254 044. I intend to use crush style clamps, similar to what comes on the factory pump with bio fuel approved, submersible line. Ideally, I'd like to find some corrugated plastic line, but we'll see how that goes.

The pump is E85 approved and flows 260L/Hr @ 5 bar and 14V. I still need to verify the supply voltage to our factory pump, but either way, I'll find a way to properly supply the power it needs. I've chosen this pump because it flows well at 5 bar, which is what our factory pump operates at. Its fully capable to 8 bar if needed, so it should handle 5 bar without a sweat.

However, it should be noted that these pumps are only expected to last 500h when running E85. This is typical for many pumps running alcohol. I'd like to somehow incorporate an hour meter to keep track of replacement intervals.

I am curious what load are they using to estimate 500h? I mean cruising around on the freeway would not nearly put as much load as WOT at the track.

I would assume that figure is at full load. It would be pointless to do the test any other way, really. Since this pump won't be in the bucket with the factory pump, it's probably best to keep the fuel tank fuller than normal, to help keep the temps down on the more exposed Bosch 044. The pump in the bucket has the advantage of always being submerged (nearly).

good luck!

GL let us know how it goes for you. The hit or miss nature of the Walbro solutions is concerning.

I have choosed this as well :-) Great pump. How about the wiring? Any specific needs?

I will probably just follow the requirements and then find heat shrinking that is alcohol compatible. Something similar to Raychem DR25. I love that stuff. I may look into developing a new bucket for both of the pumps to sit in as well. We'll see. I want it to be easily serviceable to facilitate pump changes.

If you think the 044 is a better choice than the Walbro E85, for ethanol use you are mistaken. We have Installed countless 044 pumps as they were the goto Inline pump for a long time on many applications. They do not flow near as much as the Walbro does 260 vs 455, also the Walbro is specifically designed for E85 and will outlast the Bosch as well. As far as clamps the crush clamps are better agreed. Doesn't mean worm clamps aren't working perfectly fine on hundreds of vehicles. We only use high quality clamps and throw the cheap ones that come with the pumps away. Seems like you are going to a lot of work to install an inferior product when it comes to E85 use.

How many 044 pumps have you had fail on E85? How many hours were on them at the point of failure?

If you are referring to the Walbro GSL392, as I am, the Bosch flows more. I am not interested in replacing the factory pump, but adding another in series. The 455 is just too much for my needs.

Walbro GSL392: 220L/hr @ 72.5psi 13.5V
Bosch 044: 260L/hr @ 72.5psi 14V

Heck the Bosch is rated to 220L/hr when pushing 8 bar.

Edit: Cannot even find a data sheet for that 455 Walbro, or any Walbro data sheet for that matter. A part number would be helpful.

The 044 is also a very noisy pump when running outside a tank also, I had one on my last car and ran E85 with it. Without a doubt I would do a walbro instead (ran those in several other cars) since they are made for E85. You could always use a Walbro 255HP if you think the 450 is too big. I would try to do a 2nd intank pump if you can.

I guess I didn't state it in the first post, but this will in INSIDE the tank, submerged in fuel for increased cooling. The 044 is E85 compatible.

So if i buy walbro 450 i get shitty clamps?? Where can i get the proper once and what else needed to install it properly?

Yeah the clamps that come with the kit are pretty low quality. Any decent auto parts store. Napa, etc or should have some higher quality clamps or you can find some online. The crush clamps as he stated are great clamps, but if you need to get back in there cutting them off is a pain. Connections that are leak free and stay that way for the life of the connection is what is important, not the style clamp you use. My personal favorite are the spring clamps. They are easy to remove and almost never leak as they apply constant pressure and never relax with the heat cycles. Unfortunately they are not suitable for the high pressures of our fuel systems.

I haven't seen any fail because we do not use the 044 for E85 applications. As you stated it is compatible, but it will eventually fail. You also call the Walbro cheap, if you do a quick search for the Walbro 450LPH E85 pump you will find them to be about the same or a little more than 044's, and out perform them in just about every area. Here is a link to one on amazon with a part number. http://www.amazon.com/Walbro-TIA485-...sim_sbs_auto_4 Here is a link to an 044 on Amazon http://www.amazon.com/Bosch-OEM-Exte...+044+fuel+pump

Take a look at this http://radiumauto.com/media/blog-company-news.php and if you still want to use an 044, consider it "superior", and the walbro "cheap" then you do. But the 044 actually gets lowest in flow to per dollar and the only thing is does better than the E85 pump is use less current. With when used with an external fuel pump relay is moot.

My reference to "cheap" was the $99 255lph that everyone seems to go for right away. Personally, I believe Bosch is a superior brand, and there's a reason they're in so many factory vehicles. The 455 really seems to be something nice though. Very new. I'll be contacting each companies engineering department to retrieve as much test data as possible before making a final decision. There are about 5 different brands I'm considering still.

The bosch is a great pump but like Tony stated it does flow less than current offerings. Another issue would the amperage those old pumps draw. In my opinion it might be a bit much for the factory wiring. I consider the bosch 044 to be something like ole reliable, like 60-1's lol. They aren't the best anymore, but they always work well. In this case I say walbro is the way though.
