Fuel Lab Digital Fuel Deliver Lift Pump Install

:ford:Hey new lift pump with onboard microprocessor, company gave me one to try out. Going to switch it with boost pressure, it has a variable speed option, that regulates pressure depending on fuel demand need. Pics are of some of the components uses and the electrical board I built to make it run with variable speed. Keep updated as progress develops. Ran out of time tonight to actually install on truck.

It'd be nice to have a compact clean package with pump and controller. I've been using hobbs switches to control pump speed. It works and it's easy, but isn't as clean as I'd like.

What are you going to run that setup on?

Keeping it simple, boost pressure.

Whose pump do use use now, and how do you control the speed with the hobbs switches?

Thanks.

I just use an Aeromotive regulator with boost reference hooked to the MAP sensor line post-boost relief valve. Set fuel psi to 45 @ Atmospheric and with the boost relief valve it only sees 20 psi, so it maxes out at 65 psi by 20 psi of boost and stays there past that

That is a good way to do it. This pump actually changes flow and pressure digitally with a microprocessor, I was thinking about using a boost activated switch with an inline regulator to adjust the voltage signal depending on how much boost is being delivered. I tested the pump and it reacts in miliseconds to inputs, it is fast. It is very quiet as well, you can barely here it working.

what are the advatages of having a boost reference FP? i thought that a constant FP was what these motors needed?

The pressure is constant but the drive of the motor is not. That is what the regulator is for. If fuel volume demand rises so does the speed of the motor, as boost increases so does the demand foe fuel. So why not reference boost?that is the problem with these other pumps is they are running 100% all the time, which is not good on a fuel pump no matter what the design. That would be like runniong your engine at or near redline all the time.

Quieter/Smoother at idle also with the lower pressure

Mike I take it this could also be used with the SX pump I have now? I ran the boost into my regulator to see how it effected performance but didn't regulate the pressure. I got scared and disconnected it. With fuel pressure as low as 40 at idle it was over 100 at boost. My fear was a failed regulator poring fuel into the engine.

I've got a Walbro 255 on my truck, but I've used all sorts of different pumps on other trucks I've worked on. I lower the voltage to the pump at idle and progressivly increase voltage with the hobbs switches as boost comes up. It keeps the pump happier since it's not at full output 100% of the time.

That is why you use the post side of the boost relief valve that only lets the MAP only see 20 psi of boost, with a 1:1 on the boost reference then you only increase fuel pressure by 20 psi

This pump may be a little overkill, it has a HP rating of 1800HP, huge flow rates. I am just tired of the choices out there, not everyone wants to run a fass pump. I blew mine up in less than 6 months. Wasn't worth the money I spent on it. THis systems is real well built, all billet aluminum and has a micrprocessor. It has infinita ways to be controlled electronically depending on the users needs, that the great thing about this one.Heres some more info taken from the website.

I ran my Aero 11108 black marine for over a year running it electrically off of the stock pump wiring and did not have ANY PROBLEMS :shrug: I was running it thru an ITP hi-po fuel delivery-5/8" pickup to 5/8" pushlok to a Aero 100mic ss prepump filter hooked to the pump to a 3/8" post pump pushlok hose with an ITP regulated return. ABSOLUTELY NO PROBLEMS that is until Charles got me paranoid about my stock wiring not being good enough for the pump. Bob over at Dieselsite has ran his Aero 11108 for few years with no problems. I wonder if the biggest problem with pump failure isn't just that the pre pump filters are cleaned often enough or the fact that some don't run a pre pump filter:shrug: That's my theory, but anytime a larger pump is added to the mix I feel that bigger supply lines, pre pump filtration, and a regulated return is needed. Once I add enough things to my 06 to need more fuel I'm going straight for the black Aero 11108 with my prior setup again. JMHO
