I just said this four messages ago. Did changing my avatar throw people for a loop?
This will be -fine- I promise. And trust me, MHD/BM3/MG1, etc are all going to have the same problem.
But. This. Will Be. Fine.
I knew I shouldn't have changed the fucking avatar.
There's no reason why the components won't work together. It's a pump, a relay, and some lines/injectors. As far as everything bolting up nicely and sitting in the tank.. no idea. But they should be able to sort it all.
Bad engineering. When you close the door, the air pressure in the car increases and bounces the trunk up a little and it slams closed. Use the door bottom, leave the door open, and try it (or leave windows open), and it works fine.
