I don't give a **** about there bolshit pump or products all i care is customer service i send them few messages and emails and make two phone calls but couldn't get any answers or resolution . Thank you all the people that try to help with advise but I'm looking for professional solution and not home self made mechanics .

The common response from the professionals in this thread, and the home mechanic is identical. That there was a faulty install. We honestly want to help, but denying the possibility of a faulty install and blaming a part that is in 300+ raptors a year doesn't solve anything.

We just want you to step back, and read what everyone with knowledge in this thread is telling you. That the install is the issue.

I'm not sure how you can be upset at the product. Its sort of like being mad at the doctor who prescribed you medication that you didnt use as directed, and then you were upset it didnt cure you. We're asking you to make certain youre taking the medicine as directed, and you just keep saying the medicine doesn't work without answering our questions.

I guess this is where we are at with it, just to make it as straightforward and factual as possible.

#1 this fuel pump is only intended to be an upgrade if you have exceeded the limitations of the stock pump.

#2 if you are past the limits of the pump, the injectors might have enough headway in them to offset the loss in pressure associated with exceeding the limit of the pump. This is not an ideal situation, but it does keep the engine happy.

#2a if #2 is true, then putting in our pump will keep the pressure drop at bay, but if the injectors were picking up the slack then you aren;t going to show any change in performance. Only durability.

#3 we have this pump in builds approaching 700hp (the limit of the blower) and it does exactly what we need it to with no pressure drop.

#4 never have we had an issue with running these out of fuel prematurely. As eluded to above by another member. Either A. You are actually running out of fuel at a 1/4 tank, which means that the install is done improperly. or B. You actually are empty, while still showing a 1/4 tank, which means the install was done improperly.

Im in favor of #4, what type of float system is on our trucks, if its the float and arm system, I could see the arm being bent, and or forced back in the tank, causing false readings, I for one would go back to the install, and check, If all is correct, then I would have made a point to contact the seller to resolve the problem, If one sinks a sume of money in something, why give up so easy. Just my 2 cents,and looking for change.

I agree. He or she is just bitching about service because they don't like the product and trying to make a vendors day miserable. Livernois I applaud your patience, maturity and professionalism, clearly a few words some members don't understand.

One thing that I'm looking for is, we all know that you can add and remove fuel in the SCT software.
But I haven't been able to get a clear answer as to, "can you increase fuel rail pressure and increase duty cycle of the fuel pump using the SCT software?"
And the second question is can the Raptor's stock fuel rails and lines handle said increases.
This would certainly make a difference on using a stronger fuel pump.
I do not wish to address that other (foul mouthed, ignorant, insulting) person from NYC any longer, but I always enjoyed your informative posts and like to add my 'professional' (mechanical systems, fluid power; control systems from electro/pneumatic/mechanical to computerized) two cents worth.
Any pressurized fluid system will be designed to withstand a multiple of the normal working pressure (working, max, proof, burst pressure)
So, a increase of <50% should be below the proof pressure.
Just make sure that the injectors still can open and close without leaking.
As to fuel delivery: if you only experience momentary drops in pressure (reaching max RPM at max load) I would install an accumulator.
It would supply extra flow at system pressure and also smooth out the pressure fluctuations between the pumps start and stop points.

It's a good idea if it does solve any issues for someone experiencing pressure drops.
But I'll leave that to the experts.

JDM said they where looking into making a return fuel system for the Raptor similar to what the Mustang guys do.

Don't know where there at with that or if it's worth it since most of us are not in that power range.

I've been running the stock pump on 505 rwhp and no pump failures yet so is this really necessary ?? Ive had the s/c and a 72 mm pulley on for over a year, I hear if you go to a 60 something mm pulley you need 60lb injectors but never heard of a pump upgrade... Just curious is all.

Basically anything over 500rwhp needs some type of increase in fuel flow. Pump, BAP, or methanol, something has to be added. The injectors are good until ~575 and then above that we move to an ID725 or ID850 depending on power.

Are you saying the stock injectors are good for 575rwhp? I've never heard of a s/c install without adding injectors. Just trying to learn, not stir any pots.

I was referring to the 47# injector that we use in our whipple and procharger builds. Sorry about the confusion.
