A lot of us bypass the plastic thermostatic tee on the fuel filter. Here is something that you can use to eliminate the thermostatic valve and dress up your engine compartment a little bit at the same time. It's made from billet and has a tube for for the ends of the hose that you are taking off the thermostatic valve so everything stays nice and orderly.
We eliminated the plastic tee from my fuel system because we didn't want hot fuel from the injection pump return recirculating back into the suction of the injection pump. We know it's supposed to close off at 85 degreesF, but we just don't trust it. Also, we've seen enough "bubble trouble" in fuel lines that were caused by a bad seal on the plastic tee to just want to get rid of it.
Think of it as an engine dress-up piece with a benefit of cooler fuel.
