Relocating your Air Filter is one of the most important steps when installing your HornBlasters kit. If you are mounting your compressor outside the vehicle, chances are it's going to get wet at some point in its lifetime. No problem, right? Only if your air filter has been relocated properly. If the air filter is mounted right onto the compressor, it can get wet and ultimately allow the compressor to breathe in moisture/debris. This can/will lead to issues with the compressor and eventually failure.
Your air compressor came with two of the barbed fittings pictured above, a set of mounting hardware, and an air filter housing (pictured below).
Start by threading the male (threaded) fitting into the compressor. No teflon tape is required for these fittings as they will not be holding back any pressure. If teflon tape is used, it is possible for pieces of it to get stuck within your air compressor.
Thread the female fitting onto the male thread of the filter housing, so that you end up with the following:
Finally, locate a good spot for the filter housing. You ideally would mount this in a high/dry location such as the cab, but any area where water will not reach the filter will work.
At this point, you can use the supplied roll of 3/8" air line provided with the compressor to connect the compressor to the filter housing, as shown below:
Your air compressor is now ready for use, through all conditions!
