Its an ebay cheapo ..but it works
I looked at several upgraded units only to see that most don't hold line pressure
I'm going to try and move the check valve to just after the injectors and see what happens.
In the meantime another issue has come up! I ignored it the first few times but now it's doing it more often. Im blowing the engine fuse which powers the fuel pump. I put a 20 amp fuse in the first time it did this and went a few months and it did it again ..went to a 30 amp and it went a few more months and did it again. both times I was stopped. This last time I was cruising home and the fuse blew and I was able to coast for a block and a half and made it to my driveway.
I unerstand it could be several items causing this , relay resistor,alternator,fuel pump,or the circuit opening relay. The last thing I remember doing was switching to a turbo fuel pump so maybe thats whats causing the problem |

Honestly, I have no idea what your issue is at this point. Maybe if I had the car in front of me.
There isn't a Mazdatrix injector pressure bleed installed, is there? |

| Hey AC ..well it finally let me down on the Florida turnpike crusing at 80 mph. the fuse blew again , but this time it was not accepting a new fuse without blowing. So I had it towed and I went through the hole fuel system diagnostic only to find everything within spec. So I came to the conclusion I had a short circuit and starting disconnecting one thing at a time , fuel relay ,fuel pump, resistor relay, alternator etc .. while a new fuse was in to see what happens. Thats where I got lucky and saw the dash smoke comming out from under the steering wheel. I removed the lower trim piece and found a wire that had some insulation rubbed off and was shorting. Clipped and taped it ..Bingo |

Hey AC ..your famous !! your 30 seconds of fame in a hemmings article :
http://www.hemmings.com/hsx/stories/2009/12/01/hmn_buyers_guide1.html
My car is still running great with only the fuel rail line pressure issue to deal with, I also removed the dashpot on the TB and noticed a tendency for the engine to stall so I will put it back on , did this because my brazed ( pressure regulator removed for a copper pipe cap )stock fuel rail sprung a leak !! and it was a bitch to get to with the dashpot just above it. |

Looks like they lifted a lot from my website, so nice of them to link to it. 
Yep, with the dashpot removed the stock ECU and BAC can't compensate fast enough for a falling throttle. Oddly, a standalone can manage this just fine using the BAC to emulate the dashpot function. |

That's no an option.  Partially because I don't have a car to test it on, and mosstly because I'm insanely busy. |
