Parts needed:
1) External fuel pump from an 88 ford F150 (about $30 new)
2) boost controlled switch (Hobbs switch - available from Napa $24)
3) 'Cold start' fuel injector from an 80s VW or Audi ($5 at pick your part)
4) Braided #4AN hose (or high pressure fuel line)
5) 1/8" NPT to 5/16" hose fitting
6) Relay
7) on/off switch
8) msc wiring
1) drill a hole in bottom the stock windshield washer resevior. Tap for 1/8" NPT and insert hose fitting (a bit of epoxy helps to ensure no leaks)
2) Mount fuel pump in inner front facia near the resevior (remember a fuel pump likes to push, not suck!)
3) Run hose from resevior to inlet of pump.
4) Run hose from pump to the inlet pressure pipe (cold side of intercooler before the throttle body)
5) Mount cold start injector in the pressure pipe (NOS did a study - best place to introduce gas/NOS/water/etc is 6" before the TB for best atomization). I threaded the injector and screwed it into place. There are mounting holes on the injector that could be used as well.
6) connect hose from pump to injector
7) Wire up the relay (fused power from battery, ground)
8) Wire up the boost switch - use only a boost source from the UPP (or a boost vacuum source with a one way check valve - the switches DO NOT like vacuum!) Use a switched 12v source (you do not want the injection system to engage when the engine is not running!) with the on/off switch in line so you have control over the whole system
9) Wire the boost switch to turn on the relay.
10) Wire the relay to turn on the pump and the injector
