Default 2018 F150 5.0 Whipple Supercharger Fuel Pump Testing (DW400 also)

I'm wanting to be able to run E85 or a mixure of it in my 2018 Whipple supercharged F150.

After reading about the 2018 Mustang Whipple stage 2 coming with a DW400 replacement in-tank Pump due to the stock pump running out of fuel, I figured I would reach out to Deatschwerks and see if they had any info on the F150 pump.

Andy from DW tech support responded to my inquiry stating "they had no info on the 2018 F150 pumps and didn't know if their DW400 would fit". But if I was willing to send them my pump they would do some R&D and only charge me for the pump it worked.

My truck is a daily driver so, I ordered a brand new pump assembly for my vin number (5.0 flex fuel truck) and shipped it to them.

Andy flow tested my New stock pump and then modified the basket and fitted a DW400 in its place and tested the DW400 in the modiefed assembly.

Attached are the flow numbers of both the Stock 2018 pump and the DW400 from DW tech support R&D team.




If you are interested in a drop in replacement pump DW now sells a DW400 kit for the 2018 F150 5.0 and also offers installation as a service if you want to send it to them.

UPDATE: 12/28/2018

I sent my pump back to DW and had them install an internal check valve to keep from having extended crank times and rough starts reported by other members (F150 and mustang owners with out an external or internal check valve to keep the fuel pressure from bleeding off after the pump primes)


Here is the DW400 flow numbers inside the OEM fuel pump housing tested at the voltage commanded by the Whipple tune (it ramps up for the fuel demand)

Before the internal check valve is installed




Here is After the internal check valve is installed

Itís a simple install really. Cut out the 3 tabs inside the basket and the pump slides right in. Plumb it with some 3/8Ē hose, wire it and youíre done. Did they add a check valve? If not look at the thread I just started down below.

I don't think they did (and its several hundred miles west of me, so I can't check it right now)

After reading your post, I am tempted to call them and ask about it.

I would. I learned the hard way. Left my truck parked for 4 days while I was away and it ran rough for 10 minutes while it purged all the air out of the system again.

I called DW on Monday and talked to a tech support guys and he said they are now making a pump with a check valve for an F150. This might be the results of work that was started by TX-RIPPER.

The tech transferred me so a sales guy and I asked if I could order one. He didn't have a part number yet and would call me back. That was Monday and no call yet. I'll give them a call tomorrow.

I'm looking at those flow charts and it looks like the DW pump draws considerably more current. A larger gauge wire might be a good idea to reduce voltage drop.

The DW400 kit comes with a thicker plug and play wiring harness from the top hat to the pump.

Update: I was about to install the new fuel pump assembly (DW400 in it), and started to think about the extended crank time that UNBROKEN experienced...

So I reached out to Dorian Johnson and asked it he had the same problem. He said he did and fixed it the same way UNBROKEN did.

After our little chat I called DeatschWerks tech and spoke with Chris (who helped with this R&D on fitting to DW400 in the factory assembly) and chatted about the extended crank time and adding a check valve ect.

From the testing that DW has done they know that adding a check valve internally in the DW400 reduces flow by 5-7% and adding a check valve externally even if its a -6 or -8 will still reduce flow by 3-5%.

So I decided to send the assembly back to DW and have them fit it with in internal check valve.

I also requested the pump be tested at the voltages that the Whipple tune commands (both before and after the check valve) so we can get an idea of what the pump flows in the basket (like its in tank).

Guys that put a check valve. Whereabouts did you place it?

Edit: NVM it was super obvious where to put it.

I'm an idiot on this stuff. If you run this pumps do you still need to run something like a JMS pump booster?
