I agree the braided is somewhat overkill for low pressure systems. However the abrasion resistance provided by the stainless braid is a big safety feature. ESPECIALLY when you're routing it in tight confines like the smugglers box and center tunnel. Also, some organizations require braid inside the car. The center tunnel is unfortunately arguably inside the car, considering there are openings in the tunnel to the cabin.

I like the push-lock Aeroquip "socketless" or Earl's push on hose and fittings where braid isn't a must. It's very tough and not extremely expensive. Easy to work with too. All you need are some cable cutters (cuts hose very cleanly) or a very sharp utility knife, some heat and assembly oil.

That system confuses me. I can't see how it's a circulating system from the pictures. If it dead ends at each carb, where is the return back to the fuel cell? Is it a double dead head- one pump for each carb trio? That would be odd because if one pump fails you've got one bank of cylinders down on fuel.

Grady's advice is hardly lame. This fellow has more Porsche & racing knowledge than an army of us could ever hope to possess!
