El Doc 3.0T Dual LPFP Upgrade

El Doc Solutions has done it again with this dual upgraded LPFP upgrade for the B8/B8.5 S4/S5 and C7/C7.5 A6/A7

This is a complete assembly, not just drop in fuel pumps! Wiring harness and controller included!

B8 owners require the B8 to B8.5 Conversion harness! (more info at bottom)

*Stock pump flows - 60 GPH or 225LPH @40 PSI fuel pressure

*Dual brushless pump flows:

- 135 GPH or 511 LPH @40 PSI fuel pressure

- 120 GPH or 455 LPH @ 60 PSI fuel pressure

A common question or request that comes up is what about adding a Walbro 450. When you see the rating of a Walbro, it is taken close to the end of the pump, without taking into account any flow loss due to factory fuel pump assemblies.

*Adding a side saddle Walbro flows:

-120 GPH or 455 LPH @ 40 PSI fuel pressure
- 105 GPH or 400 LPH @ 60 PSI fuel pressure

*All testing was done on my fuel bench, through an unmodified OEM fuel filter lid, to replicate as close to a real world situation as possible.

To give a reference for available fuel overhead. Testing Jackal conducted has been seeing low 40% LPFP duty cycle numbers at an estimated 500-550 WHP car.

For the CREC folks, this will be part of the answer to FULL E85 for stage 2+

Two different options, one for the S4/5 B8/B8.5 and one for the A6 C7/7.5
*Unconfirmed fitment for the A4 B8/B8.5 or S6 C7/7.5

Billet fuel pump retainer covers critical areas of the bucket. This keeps fuel in the bucket during launches reducing slosh away from the pump.

This pump assembly is engineered to have two OEM siphons. No drilling holes into the bucket to assist the pumps in gravity feeding fuel into the bucket during low fuel level conditions because there is only one or no siphon. Half tank and below drivability issues are a thing of the past.

Fuel pump assembly installs inside the tank just like OEM. No build a pump in the tank. The harness is plug and play except for a few supplied T-taps. It can be hardwired if the end user chooses to do so. No running vacuum lines for a hobbs switch or additional wiring around the car. Everything is centrally located for an easy installation.
No need to run WMI to supplement fuel pressure with ported blowers on E40.
Able to run Multi Port Injection on pump E85 all the way to E85 and higher, if you like it spicy.

Early B8 Models 

B8 to B8.5 harness is required

*Caution* required tuning change to use a brushless pump in a B8 car. Requires a current Jackal tune for pump signal change and communication with jackal for calibration option or competent tuner to modify signal!!!!

Plug and play installation.

Plugs right into the current B8 wiring harness to convert the archaic
brushed fuel pump system into the more robust and improved brushless fuel pump system.

Required to run El Doc’s Dual Brushless Fuel Pump Assembly.

*Requires tuning calibration to change the PWM signal - Jackal Offers this
