All fuelab 41401 owners

I am about to order a fuelab 41401 pump and just wanted to know what everyone is doing for pump speed control? Just running full speed all the time or just used a switch? I was thinking about finding a 5v pressure sensor and using boost pressure to control pump speed? Bad idea? Let me know your thoughts.

I Have a 41402. I currently have it hard wired at low speed and it keeps up with my 205/75's without any problems. You definitely don't want to run it at high speed all the time. At low speed it puts out about what the 41401 does at high speed. I recommend you rethink which pump to buy.

Fuelab has a pressure regulator that controls the speed of the pump. I will be installing the 41401 and the 529 regulator in two weeks. Here is a link to the FPR.

The 41401 has been proven to supply plenty of fuel to 400cc injectors, Im pretty sure he will be fine.

Thanks for the input guys I'll check out that regulator. Maybe just go with the larger pump if it's not too much more

The regulator isn't cheap and involves more wiring and complexity. As I said the 41402 in low speed is comparable to the 41401 or an Aeromotive 1000 at high speed. No muss no fuss and since it is always being run at low speed should last forever. I like simple. And the cost differnce between the 41401 with the 529 FPR and a 41402 with a 515 FPR is insignificant.

I've been running the fuelab pump that Dennis at Strictly Diesel sells... I got mine from him. Been on for 4 years and going strong. You should run it at low speed.

For most guys, the 41401 on low speed is enough fuel. Although some require the high speed setting on occasion, it's not very common.

If you wanted to go with the electronic regulator- the install/setup is as easy as can be. You set the pressure just the same as any other regulator- with the adjustment screw on top. There is a small wiring harness that comes out of the bottom of the pump with 4 wires: power, ground, signal to the pump and a 4th wire that can be used for data logging (in this application I don't see how that wire would be of any use). There's no calibration or anything like that.
