Last year, I replaced my E39 (M54) fuel filter with a new Hengst brand from FCPEuro.

Hengst is a reputable German brand. And my filter was not made in Asia.

However, I got a defective one, and I ended up with 60psi at the fuel rail and very rich fuel trims...Took a while to figure it out...I posted it on the E39 group and at least one other member had a problem with a Hengst brand. I returned it and replaced with a Meyle (I think).
