1G Couple questions while removing my stock fuel lines... And installing walbro 450

[Geeb]

In the first pic is this a stock inline mini filter or something? Where is this incorporated? I tried feeling it and I couldn't figure is it part of the feed or return? Or am I way off?

Second pic.. I see the feed line, the return line, the 2 brake lines, then there's a 5th line in the bundle and on my car it's just cut not connected to anything.. What is this supposed to be? I'm pointing at it...

I'm not leaving any line stock from the pump all the way back to the tank..

From the walbro 450
I'm connecting the submersible fuel line,
then to a barb fitting
to 8an bulkhead fitting with Teflon washers
(stock feed on hanger cut and drilled out)
to 8an 90°
to 8an fuel line
to fuelab filter (ss element)
to sard fuel rail
to 6an return line
to aeromotive afpr
to 6an return line
to gm flex fuel sensor
to 6an return line
To tank

Plus some dif 90 and straight fittings and stuff in between..

But since I'm doing all this I won't need any of the stock stuff so anything I can eliminate, let me know.

Thanks guys.

I believe the blue thing in the first pic is a check valve for emissions purposes. The 2nd pic is like a breather line

The blue filter is part of your charcoal canister. I just have that routed to my rear wheel well, its just a tank vent.

I just tore out everything, if your running the 450 your going to have to modify the hanger as its longer than the walbro 190-255. I just removed the stock line coming thought the hanger and installed a 6an to barb fitting. There are many ways you can do it.....depends on your plans

Thanks guys... Are there any pros or cons for leaving it in, or ripping it out?

And the second pic. The breather line that boosted pointed out. What do people that are trying to clean up their engine bays, do to that? Could I just dump it somewhere else? Or cut the hardline shorter and let it vent under the car or something? I want to have it unseen but I want to do it safely.
