Running new fuel lines

My car sat for years and this created all sorts of issues. I would like to run new fuel hoses from front to back but a bit lost on the routing of the lines. I had the tank cleaned and coated and also purchased a new Walbro 400 pump. I would only have to run lines to the Y fuel block that was installed with -6 lines to upgraded fuel rails.
So my question is how to run the lines from the pump to include the charcoal canister and what do I eliminate?
Am I correct to run -6 as the feed and -6 on the return?

Thanks for any assistance.

NLA? Would it be that simple as to just clamping a hose on each end?

Are you wanting to replace the stock metal hard lines? Are they damaged beyond repair?

The lines are fine. The only questionable thing is that since the car sat for a long time I noticed some rust residue on the opening of the hard line. This concerns me because i'm not sure if I can get all that out. So I figured if I have to replace them might as well run braided hose instead. But from what I have read the stock lines are enough for 500+ HP

Yeah the stock lines are a good way to go. Also running all new braided lines can get REALLY expensive.

If it's just some surface rust you may just want to hit it with some rust converter and be done with it. The lines unbolt from the car fairly easily if you need to work on them off the car.

if you're really set on running new lines Radium Engineering has a -8an feed kit with low pressure drop high efficiency filter mounted on the rear subframe for $289 or so.

Looks like the supply and return are still available if you want to go new. Evap is NLA

RikTT,

I went to a place in LIC NY. $245 to clean and seal. I'm happy with the results.

Search for his contact info, he is very much in business selling parts. No longer with Malloy, he's on his own and still doing great prices and service.

it's with their surge tank setup, you just deselect the surge tank and tick the feed kit and you can order it separately, select stainless or microglass filter element.
