As per title..

going by the p/n catalogue , it says the 040 flows 102L/hr @ 6.5bar..

I will most likely run a GT2871elim before going to GT3076R.. 400hp is the end goal.

My tune calls for 3bar.. Any one have any idea what it would flow at 3bar and would it suffice?

If your only running a 3076r a 255lph walbro should suffice if your running pump gas. However if you plan on running E85 your going to need some serious flow.


If your deadset on the bosch though I would skip on the 040 and just get a 044. Flow is better and its pretty much the same price.

There are also some other options though: DW300 http://www.deatschwerks.com/products/fuel-pumps/dw300-in-tank-fuel-pump and I also heard walbro came out with a pretty badass 400lph turbine style pump.

I only am looking at the 040 because in all the parts catalogues from Bosch, the 044 is listed as an inline pump aka, NOT in-tank..

I plan on running E85 for sure..

Bosch 044 (PN: 0580254044) can be used both internally and externally. I have that pump in the stock pump location currently.

And the other reason I asked is because there is one for sale locally for $70..

Could I run the 040 intank and then later on when I upgrade put a 044 inline under the car?

Is it necessary to run a surge tank when you run an inline pump?

I have been running a 044 pump in my tank for years, I added 2 more later on as inline pumps. It can be used either way.

The 040 pump isn't really used that much anymore, most people have moved to the 005 pump if not using the 044. For your power even the Walbro 255 HP pump is plenty, just make sure to keep the fuel pressure down around 3 bar.

It is best to run 1 pump, so putting one in the tank is a better choice. This way if the pump cuts out the car just stops running, if 1 pump cuts out while running dual pumps then you can lean out way before the engine stops running.

Would 040 suffice for my goals currently?
