For the fuel pump and return lines, first I used the supplied block off plate to block off the mechanical pump hole. It fit perfectly, even though the book said it was for chebby / chrysler engines. I mounted the fuel pump on the frame right under the gas tank, by where the fuel line outlet is. I utilized the existing steel fuel line, and ran rubber fuel injection hose from that up to the TBI. For the return line, I just paralleled the first line. I drilled a interference hole in the rubber fuel neck and stuck it in. It doesn't leak.
I loaded a base map for a SBC 350. It seems to be running lean on that; I still have some tuning to do.
I'd be happy to help anyone else who decides to upgrade to TBI. (over the internet of course
)

Holley makes a loc out for the FE dist. Part No. 881-120. It locks the mech and vac advance. so that you can use a computer to controll the timeing. I will be using it with a timing computer from MSD.

I dont see it as any less safe than the original rubber filler neck. Dont worry; I have it secured. It's a VERY tight interference fit, and it's glued in. It isn't going anywhere. The instructions even say to run it in there or at the fuel level sender.

Bah. Havent looked at it in a couple days. Still got exhaust gremlins to work out. I might go out there today and see what I can do. What I really need to do is have one of my friends from up to the college drive the thing while I tune it. It would make tuning 10x faster.

Ran into my first tuning problem. The voltage is fluctuating, causing my engine rpms to fluctuate in sync with it. It's quite annoying. Is there any other kind of voltage regulator that will give a constant voltage?

Kurt your charging system should stay at about 13.8 volts + or - .2 to .4 volts
does your injection system run off of just 12v it should...in that case you would need to run a regulator that will accept 13.8 in and 12v out to keep it constant!
Radio Shack should have something that simple..If indeed the system will only take
a constant voltage...Good Luck ...Russ

The problem is that it goes from 9.5 volts to 14 volts in a fairly cyclical pattern. What I need is something a little more involved than a simple voltage regulator, I think. I hate to pull the alternator and install a smaller pulley on it, but that may be what it comes to.
The datalogger that comes with the fuel injection shows that it is the voltage that is causing the problem. The voltage fluctuations cause changes in the injector pulse width, which change engine rpm. Rpm drops, so does voltage, and so the computer compensates. Then voltage comes back up, and so on.

Also, where is that voltage sourced from? The battery should hold it a little tighter than that.

Never been to a ranger site but I do post over at network 54 every once in a while.

Never did answer my question? does it run on 12 volts? or a constant 13.8?
It wont matter if he run a High output alt..the voltage will still drift..
It wont be constant without a regulator in between the power source and the control unit...for the injection system... Russ
