that is some pretty big line. mine is fastened to the frame connectors.
alot of fuel system with return lines require a return line bigger than supply line. you will need one massive pump to withstand g force pressure with a -12 line

Yes. I stated that wrong. On the 65 It would be either a -8 send -10 return, or a -10 send -12 return.
Either way it is alot of plumbing to try to hide safely.

I used aluminum tubing (instead of AN hose) from the pump to the regulator and hid it behind the rear subframe and subframe connectors up to the trans cross member and then enlarge one of the holes in the crossmember and push it through there before attaching it permently with hose clamps and self tapping screws to the front sub frames and sub frame connectors. I do clean it well before running it with laquer thinner so I can use Zinc Chromate primer and then black paint to hide it My current car has #8 to the front only, I used a Magnafuel pump with the return line from the pump to the tank instaed of using a return style regulator with another gas line from the front back to the tank Is this a street and strip or race only car? The reason I'm asking is my Duster is both and when I called BG about using their 280 or 400 pump on the stret they said absolutely not, neither one was designed to be continous duty, drag race only Magenfuel said no problems with using thier pumps on the street I used a #8 line to the front on the Duster, #10 from the tank to the pump. I will use a #12 from the tank to the pump and a #10 from the pump to the front on my new car, 1965 Dart with 900 HP. I bought a Parker AN flaring tool that burnishes and flares at the same time also Buy the tubing nuts and sleeve washers and 25 ft roll of soft aluminum tubing and have fun BTW, Summit sells the tubing in several different colors that are anadised (SP?) if your using alcholol

Thanks for the replies guys. Seriously. My biggest problem is the area right by the kick up on the frame above the rear-end. The factory line crosses from inside of the frame rail to the outside here. My problem is with these bigger lines there is nowhere to cross to the outside near where the front spring hangers are. I was going to run the line on the inside of the frame rail but was worried about the rear u-joint breaking and sending the driveshaft into the fuel line. Cab: The car is street/strip. The pump is the 220HR which is street/strip. When I spoke to the guys at Barry Grant they said it shouldn't have a problem feeding 750HP, which is what I am shooting for with the hemi the 65 is getting. The 64 has a 413 maxi, so I think that -8 send line should be sufficient. But it is still a pain to route due to its larger size. Again, I just wanted to hear what other people were doing and what was working, safe, and passing tech. -Jason

This is where mine is cut and has a tube welded in. The tube is located between the outer rail and the inside lower bolt hole for the spring hanger. I cut the bottom of the tube so the line would fit into it from the bottom. If your running leaf springs I would weld in a tube from the inside of the rail to the outside at about a 30 degree angle to the centerline of the car. Doug Not car is at body shop so the tube is not in the picture,reference only

Thanks for the replies and pics guys! Bigcube: I like the idea of being able to run the return down the driver side, but how/where did you cross over? I am guessing your reg is on the passenger side or thereabouts so you would have to cross over to the driver side with the return line. I didn't think fuel lines were allowed on the firewall so where did you do it and still pass tech? dvw: I like the notch and tube idea. -Jason

Lines are on the outside of the firewall, outside the frame rails. Regulators are in the front. No issues with tech.
