A InstaMorph fuel injector testing harnessHere's another great InstaMorph idea from the always creative Joe S. Joe brought us the last couple projects we've featured on the site, including the concept for making custom bungee cords. Thanks Joe for all these great project ideas!

So this week, Joe has been working on testing some fuel injectors. Pretty interesting task. Is InstaMorph up to helping out with this challenge? You betcha!

"In this project I was working on the car. Testing fuel injectors is quite involved, and not exactly a common occurrence, but the basic principle of this application could come in handy in other situations.

Normally you'd have to go to an auto junkyard, find your car, and cut off a scrap wiring connector to use in the tests. These injectors are like $150 or more, and you don't want to short one out (or cause sparks around fuel) so a proper connector is desired.

I first fabricated the 2 little metal clip parts by hacking a common connector, then soldered on the wires, and then attached them to the injector's pins. Then, pressed soft IM into the cavity to encapsulate the clips.

IM has fine electrical resistance and is immune to (all?) common solvents and fuels and seems perfectly suited for this one..

This is a low voltage, low power DC application. I'd strongly caution against using IM on any wiring that carries a higher load and becomes warm, thus softening the IM."

Couldn't have said it better ourselves Joe. The last point about high voltage/current wires, whether using InstaMorph or not, is especially important, thanks for pointing it out. Also, this project was designed for testing components, but is not used for when the vehicle was in motion. We do not recommend replacing critical parts of your car with InstaMorph, even if it may work really well.
