So I am installing my 125 shot on my car before the shootout, but i cant figure out where to put the fuel line booster? does it go before the fuel filter or after and where at?

How many of you have experience with these? I was looking for a how to and all i found was guys upgrading their fuel pumps... so that leads me to my next question, will my fuel pump with the booster be enough?

And lastly on a non-fuel related issue I cant seem to figure out the MSD harness for the Mallory 685 box. Any help is mucho appreciated with all this, Thanks!

I looped mine before the filter. Although the corret thing to do would be to put a high flowing intank for your furl needs. Although the booster pump will help from FP from going to low when you hit it you really need to put an intank in there.

The MSD harness connects to your exesiting couil harness. The dual male connects to the dual female and then yoyu plug in the single on the coil.

I have a digital 6 so it may be a litle different idk. I went to msd's website to get the instructions. The harness i know is correct. But the way you wire your up should e the same.

I initially installed a 255L booster pump looped in before the fuel filter. I had issues with fuel delivery from the start. Only after I decided that it had to be a weakening stock in-tank pump and replacing it with a Racetronix kit did I find that during the looping into the stock lines with the booster caused the stock plastic fuel line to kink slightly resulting in a restriction that caused a drop in fuel pressure when spraying causing the FPSS to kick the N20 off.

The point to my story is if you go the booster pump route be sure to carefully route all of the lines and be sure not to kink anything.
