Guys with the Honda FPR

Does your car seem to start a lot harder now? I love the regulator as it's very consistent, but if the car is left for an hour or more, it takes 2-3 seconds for it to fire up. I'm assuming this is due to a loss of fuel pressure in the lines and I know it has something to do with the FPR (since the car fired up immediately every time right before I installed it). I've been looking for any small leak around the fuel rails and FPR but none seem to show up, so the system appears to be sealed.

I have an aeromotive FPR and mine does the same thing. Sits a few hours and the fuel pressure is bled down, need about 2 secs to fire up. I'm not sure it's supposed to be this way though, as I seem to remember the FPR being better at holding pressure just a year ago (atleast not bleeding it down so darn fast).

Yeah, mine held pressure for a little bit initially, but now it bleeds down pretty quick. It does take an extra second to finally kick over, but I think the benefits out weigh that small negative.

Mine does take a second or two longer to start, but just assumed it was my maft-pro powering up before the car would start. But now that you mention it I installed both the maft-pro and honda AFPR at the same time. I also noticed that with the stock FPR, fuel pressure would drop incredibly slowly after shutting off the car, but now with the honda one it drops a lot quicker. It's not really a big deal though, I don't even notice the extra second it takes to start up anymore.

yep same thing. Held pressure for the first few months, now it drops almost as soon as you kill the key. Takes twice as long to start.

Did you switch orifices when you got yours? I stuck with the one it came with, but was wondering if that would possibly make a difference.

[Chris@Rvengeperformance]

nope didn't change anything. The orifice that comes with the AEM installed stock is BARELY large enough for our application and a hotwired walbro or supra pump.
