i want to replace all my OEM hoses, some reasons being they are the OEM ones from 69 and whats not OEM is just cut and has a rubber hose connecting it with hose clamps.

i am looking to go with a complete braided steel line kit from Summit with the AN fittings. i have never worked with AN fittings so i am alittle unsure how it all works and what the negative numbers (-6, -8....) mean. is this a good setup to go with? i have an OEM tank with a Holley Blue electric pump going into a regulator than into a Holley 650cfm double pumper 4bbl. any tips or links to what i should get for this setup? thanks in advance.

I did the same thing and it works great. One problem I ran into was routing the line opposite of stock (passenger side). It gets pretty clost to the exhaust so I bought some DEI heat sleeves and put them on there. In the summer it would vapor lock sometimes. And that deffinately helped.

I don't remember the AN fitting sizes, but when you call summitt, talk to the salesman and they should be able to help you out on that stuff. I have had good luck with them. I can post a pic tomorrow if it will help. I ran the line into a regulator with a pressure gauge just under the hood hinge, then to the carb from there.

Basically, the dash numbers are the size in 1/16's of an inch. For example, a -6 would be 6/16" or equivalent to a 3/8" hose. -12 = 12/16 or 3/4", etc...

Everybody should try braided hose once in their life. Love those splinters! Looks nice when finished though.

would it be good to run a braided hose from tank to carb though? i wasnt sure if i should go 100% hose or use some hose and some steel lines.

also i have a Holley Blue electric fuel pump, where should i put this? right after the tank? before the carb feed? and do i need to route a return line for the Holley?

personally i would use as much steel line as possible, after all the braided hose is still rubber underneath and can kink and get caught on stuff in the road, besides braided hose is so much more expensive than steel line. i would use braided anywhere you have to join 2 steel lines together and from the stock pump to the carb, on your setup i would run braided line from the tank to the blue pump and steel from the pump to the fender well where the stock steel line goes into the engine compartment and then braided again from there.

I have run Braided line the entire way from trunk to carb and never had a problem.
It takes a little more work to get it mounted under the car and looking good where a steel line would be alot easier to conceal.

Also, my fuel pump is mounted right after the tank. It was my understanding that, that is the best place to mount it. Don't forget to run a fuel pressure regulator as well. Good luck.

I just did that to my fastback. I think you need something like 12', use -8an fittings if possible. Also it does not cost that much to have the supplier place the fittings on for you so you don't get the metal splinters. I used the existing holes on the car to secure fuel line so no additional holes were needed.

If you can use straight an fittings that will be the cheapest. Every angle increases it quite a bit. They make a specific AN fitting for the fender wall. You might want to think about placing a in-line fuel filter (Canton makes one that I bought and you can replace the filters. I bought it from streetortrack.com) with a chicken valve so ease of fliter removal as well.
