Yup.

Wow you are correct, just did a little search and found it calls for 3 times the required demand. Over 100 PSI, thats crazy. I assumed it was pretty much on par with all other common rails @ the 10-20 psi range. Hell those pumps may be the ticket for 6.0/7.3 guys then if you retro fit one.

Which is why it is going to work so well :thumbup: :ford:

Great Idea!

The higher supply pressure is actually a smart move from the factory. Low fuel pressure to the HPFP's in common rails have been an issue for years. Without an adequate supply the pumps are prone to failures.

For sure, I smell what your stepping in now. I never would have guessed that it would demand that much though.

Yes sir. Not only that, we have a cp3, which flows more than a cp4, and a set of moderately sized nozzles.

Whats the power goal ?

 

[Super08Duty]

750 is the goal

 

[NathannialD]

the spec is 60-70psi, and that is about what we see on the shop 6.7

not really since the factory duramax has never had a lift pump, while it does help not really a cause of failure.

:whs: heard this from H&S as well

The duramax loves a lift pump though

[WHY NOT]

Multiple FASS systems have been used...The goal for this truck is to have a reliable streetable setup that makes alot of power. That being said, because the 6.7 operates at higher pressures than the 6.4 LPFS..finding a reliable pump that flows enough volume is a task. Im sure I will catch flack for this, but Aeromotive, Fuel lab, Airdog, and FASS all fail, and do so relatively quick (~1 year, unless its Airdog, then you have a few months). So we decided to build on top of what highly educated individuals engineered, and do it again. For filtration ease, reliability, ease of access, and replacement if need be. Not to mention well stocked dealerships usuallg have everything we need. Both systems are independently supplied and returned, but equalize in a motor mounted filter head before the fuel is introduced into both pumps. The electrical system is not piggybacking off of the original lpfp, it will have an entirely seperate harness, containing factory parts.

Very cool, thanks for the good answer. Can't wait to see this truck all done up. Any thoughts of having a kit for this in the future so those of us that are electrically stupid could run this set up?

 

[Erikclaw]

So, since no turbo info has been given. I am guessing a 75mm?? Love the fuel system design, makes sense.

No problem. Yes I have thought about it. Have to wait until im done to price it out

Dont be gay, make some money and sell some parts

 

[SEABEE08FX4]

What's everyone's thoughts on why Ford calls for so much pressure and GM none at all but both utilize the same pump?

 

[bft blue oval boys]

Ford is smarter

Thank you guys for all of the input and support.. It really helps motivate everything. Morgan and I are exhausted after today but I feel like we made a good amount of progress. Hopefully tomorrow we can have update pictures ready. Have to get some supplies and then it is back to the shop for day 2.

 

[4EverBoosted1]

Ill just place this here...

Now that is just siiiiccccckkkk
