These are two different things. Efuel is just using an electric fuel pump.
The stock fuel bowl can stay.
Unless you're talking about doing e-fuel and a bowl delete and adding a pre and post pump filter.

You CAN NOT use the stock fuel bowl with an electric fuel pump on an OBS. The stock fuel bowl is NOT designed to handle the PSI that the electric fuel pump puts out.

The stock fuel pump is a 2 stage design. The first stage is a low PSI stage that draws fuel out of the tank and into the fuel bowl. The second stage is a high PSI stage that draws fuel out of the fuel bowl and pumps it to the heads.

If you do an electric fuel pump, you MUST do a regulated return as well and eliminate the stock fuel bowl. There is no way around it.


There are many benefits to e-fuel and regulated return. You will have constant fuel PSI because you are not relying on the cam to run the fuel pump, better fuel filtration, immediate fuel PSI at start up, smoother idle, able to support WOT runs without running out of fuel at the injectors, and able to support larger injectors without running them out of fuel.

Not really, but I will list out what I used best of my ability off the top of my head.

Fuel Pump & Filter Area:
- Super Duty 7.3 electric fuel pump & bracket (eBay, Forum member, or Junk Yard)
- Stanadyne FM-100 fuel/water separator with fuel heater
- Napa final filter base (WIX 24770 or NAPA 4770)
- WIX 2 micron absolute final filter
- WIX 30 micron fuel/water separator
- 3/8" Diesel Rated Fuel Injection Hose (about 6')
- 1x 5/16" Tube x 6AN fitting
- 1x 6AN Female x 6AN Hose Barb
- 1x 3/8" brass ball valve for fuel shut off
- 1x 3/8" tube x 5/16" 90* fuel pump hookup (O'Reilly) (used to connect 3/8" fuel line to SD fuel pump)
- Misc. Fittings for filter bases


Under the Hood:
- 7/8" Freeze Plug (O'Reilly) (To seal the OEM fuel pump hole, coat with sealant and dimple the edges)
- Aeromotive 13109 Fuel PSI Regulator
- 1x 6ORB male x 6AN male (fuel PSI regulator return to tank port)
- 2x 6ORB male x 6AN male 90* Swival (fuel PSI regulator return fuel line ports)
- 4x 6AN Female x 4AN Male (fuel PSI regulator return fuel lines from heads & fuel line step down at Y fitting)
- 2x 3/8" Tube x 6AN Female (Supply and Return hard line)
- 6AN Y Block
- 2x 4AN Female x 4AN Hose Barb (Y block to head)
- 2x 1/8" NPT x 4AN Male (supply ports in the rear of the head)
- 2x 4AN Female x 4AN Hose Barb (supply ports in the rear of head)
- 1/4" Diesel Rated Fuel Injection Hose (about 5')
- 3/8" Diesel Rated Fuel Injection Hose (about 2')


Oil Pressure Switch:
- Holley 12-810


I also used a relay socket and MAXI fuse to wire to supply the power and relay for the system.


Here is what my setup under the truck looks like and some old pictures of the fuel PSI regulator setup (don't have any pictures of under the hood with the new fitting setup).
