Dual fuel pump set up?

[musty]

I have been pointed in the direction of this fourm as apprantly a few have done a dual 044 in-tank pump system.

I would like to do this for my RS4 hence the question


Any help would be grateful

just buy an aeromotive a1000 masive capacity for over 1000bhp will work with e85 etc, if not just search for it with the function available

For an RS4? Just fit a single Motorsport 044 10 bar pump as used by MRC

Need two 10 bar pumps recomemded by Doug @ MRC but want to run parrallel not inline

look at Terrybullwons setup on his S2

thanks will do

Don't know how a RS4 tank is, but this is my dual 044 setup in my CQ:

No I'm afraid. Should have taken more pictures when under construction, but didn't

Short version:
Removed inner pump holder and formed the outer one with some heat so the two pumps could be fitted. It's tight, but you make the space you need
In the bottom of the tank there are three studs used to mount the plastic holder. I extended them and fitted a bracket/fuelrail that hold down the pumps.
Also cut the tank open and fitted larger lines and fittings inside to avoid restrictions in fuel flow. 2.5L + E85 + 1.8bar = a lot of flow needed

my 2 pump setup looks similar to that. it uses a bar to join the 2 together. i got a 2l tank with 2 feeds off bottom to feed the 2 pumps.

not fitted yet.

I wouldnt have thought it possible to squeeze two pumps in there like that - seems unfeasibly tight

DP is always tight (thinking of Dual Pumps ofcourse )

One lift pump in tank and dual external pumps would maybe be easier, but this setup works OK when you get it there. I'm also using a setup with relays and a cooling fan resistor so pumps only at half speed when the flow is not needed (avoid noise and wear). Relays are triggered by ECU.

Very interesting thanks for the replys
