I purchased their water separator and fuel filter system for my 2018 RAM 3500 with 15k miles on her (she’s worn out).
I figured I’d start with the water separator in the rear. Everything went well until I started the truck up and saw fuel dripping on the floor.
I crawled back under and found the 90deg. Fitting leaking.
I gave up after a couple of diesel fuel showers and a massive mess on my shop floor.
I pulled the aftermarket system back off and started investigating.
Both fuel fittings on the BMP system are .012 smaller in diameter than the stock filter.
I reinstalled the stock water separator and have zero leaks.
I contacted BMP the following Monday.
The response I got is all the fittings are smaller and that I need to get new O-Rings for my quick disconnect fittings.
Here is an idea for them: How about selling the correct size fittings or supplying new O-rings with their system.
They have seen this before, and I’m sure nobody is changing these filters out on brand new (new O-rings) trucks.
There is now a brand new BMP fuel filter replacement system in my trash can!
