fuel fittings

So looking at all the upgrades before making my engine swap. The fuel fittings at the heads that the fuel lines connect to. They appear to be a combination check/screen valve..?? Are the checks needed? Also odd the screens are that large , after, the fuel filter. Aftermarket fittings are just open. The fuel lines to the head are .187/.275 area. The banjo bolts are .250/.0490 area. The two 1/8" holes in the banjo fitting I drilled 5/32"/.0382 area. The fittings look very restrictive so drilling out the fittings larger than the fuel lines makes sense but still wonder why those fittings have checks in them. Might be able to just pull the inners from the fittings.

Super common to remove the screen and drill them out. Doesn't really provide a benefit that is noticeable compared to the work involved though.

My 0.02, I have found bits and pieces of the vibra-lok compression sleeves on those screens enough times to feel that they are doing a service in keeping those vibra-lok viton bits out of my block's fuel galleries and the injectors themselves (the only real contaminant I expect to encounter downstream of my fuel filter). If you don't need the additional flow it really doesn't do any harm to leave them, as Justin pointed out, not a lot of gains usually, unless you are running giant injectors.
Now, you speak of engine upgrades, there are several kits out there that replace those vibra-lok connectors with JIC. I personally think that is the way to go, and then there is no need to drill out any factory check, just replace the adapter completely. I think Corey @CNCFab has it, I would have bought it a long time ago but there is an issue with the e99 where the turbo pedestal has to be NON-EBPV style and I am NOT willing to give up my EBPV!

Oh, and I don't recommend that you disassemble them to clean them, just blow them out - I found that the inner snap ring tends to permanently deform when you remove it, not very springy.

I can't stand the EBPV pedestal. Lol.

Yeah yeah, I do know I can tell the difference big time when I go outside at -50F and crank it up, it actually warms up nicely, but if you unplug the solenoid, it won't warm up till you start driving it. If you live someplace nice and warm, where it hardly gets down into the minus teens or twenties, I would tend to see and concede your point ;-)
