What is the purpose of the inline filter when you have the screw-on downstream?

Yeah that's kind of the feeling I was getting. I suppose I'll just have to take a snip and see what happens. Heat gun might help?

Wrapped things up with the truck last weekend, been running great so far.

I replaced the shredded fuel pickup strainer with some stainless mesh and a band clamp. The HVLP works great, bled the system and it fired right up. It makes about 2psi more boost at the top end and definitely fuels way faster. Might have to crank that starwheel up a bit more if ya know what I mean ;D

A 0-15psi fuel pressure gauge is on it's way, and I think I'm just going to make my own banjo bolt for the fuel pressure "signal"

Thanks again ya'll!
