The whole floor panel in that area gets warm.

I’m now thinking about cutting a few vent holes into the front part of the underbody panel to let some airflow in while driving. Also looking into adding some heat shielding around the filter and maybe isolating the bracket a bit since it’s aluminum and could be conducting heat into the filter too.

Would be interesting to know, has anyone else noticed the same issue?

@Gabe your setup looks super clean also! Would love to see what your thermal camera shows in that area after a drive. I’m sure you’ve already got a smart fix figured out..
Hey buddy, thats some great feedback... because the fuel filter is now covered, it's more work to check that temp, but I will and report back. I did heat sleeve all of the lines for just that reason.
