In an effort to not end up like this guy:
http://drugg.net/bird_roast.htm
I ask ASAP because I'm doing the install tonight (saturday) and tomorrow (sunday).
I'd like to install my FMU correctly. Simple enough, eh? Well, I just received my slightly used pair of Powerdyne inline fuel pump and FMU. For right now I'm holding off on the the fuel pump install until I see if I need it based on autotap and my fp gauge (couldn't resist the purchase though).
On to the FMU ... It's slightly different from what I was expecting. It seems like a normal FMU -- two fuel fittings on the bottom, but on the top there is a two-way vac/boost tap. Right, and that's not the end of it. One of the taps is open, and the second has a line that goes to another tee. On this other tee, one of the taps is open, and the other has a line that goes to some sorta, well, device. The line comes in and gets converted via fittings to screw into a sensor-looking thing, like scaled-down version of an oil pressure or fuel pressure sender. About half the size of the typical OP can. This "sender" has two black leads attached with screws. One black lead is ring-pigtailed. The other black lead goes to a 12Volt 5-pin relay. Yeah, more. Two relay pins jump each other, with one of the red jumps also heading to a fuse holder / 20 amp fuse, followed by a ring-pigtail. The two other relay pins are open.
Sonova*****: look at the junk to the bottom right of the fmu in this picture. THAT's WHAT I'm TALKING ABOUT! http://www.bocchicchio.com/powerdyne...S/17834_26.JPG
That's all. So here's my question --- WTF Is all this junk? I was expecting an FMU with two fuel fittings and a boost/vac feed, that's all. I figure the choices for the weird sender / relay / fuse are:
1. Some sorta sender (but why would it be fused and relayed?)
2. Some component of the inline fuel pump, that was attached to the fmu junk in the sales process, and therefore nothing at all to worry about.
3. Something for a timing retard control, or boost-a-pump control (not needed for me)
4. Some super-slick device that allows in-car ratio adjustment.
Anyway ... I figure I'll just hook the biatch up sans extra junk, cap off the extra boost/vac tap (which I can later use for an air-bleed to adjust the ratio down), and run a plain boost/vac line.
Please respond with any thoughts / experience. Thanks guys!
