if you wanted to run 2 fuel pumps then just run make a hanger assembly and hang it next to the oem pump, you would want them run in line instead of t'd off and parallel.

now i wouldnt recommend that at all though as its not going to solve a high boost lean issue and it would be a waste of time to do that alone.

both Woody, Paul and myself have been tweaking the design for a long time now for the new fuel system. it has come a long way and does work well. the leaning has been solved, we are just trying to get the fuel curve perfectly dialed in on the low end which has been taking longer then expected.

as stated above, we do have a return system on our car with a dead head rail. if we dont run out of pressure we cant run out of fuel. with the new regulators we are running pressure dropoff isn't a problem.

between the 3 of us i bet we have tried over 100 revisions to tweak the design to the point we have now. i imagine there will be another dozen more changes before all is said and done.

here is a screen shot of the zeitronix on xrays car this past weekend. at this point the low end could be dialed back with a reflash to hold a flatter afr curve but with a few more tricks up our sleeves i think we will get it even closer without needing a reflash.

ill dig up a 17:1 afr datalog from when thsi issue first started later tonight so you guys can see how far we have come.
