Mark the braided hose and wrap the area tightly with masking or electrical tape before trying to cut the hose with a sharp hacksaw or handheld cutoff wheel, and be careful to keep fraying to a minimum. For more info on installing AN hose end fittings, look in the DIY section of the October 2007 issue of CLASSIC TRUCKS, or log onto Aeromotive's Web site and click on Street Rod Pump Kit under their Instructions section. Here is the AN fitting holding fixture in action, and boy is it a life saver when putting the hose ends on. | 
For those that don't know (I am, or was rather, an AN newbie), here is a typical AN junction, a hose end, a union (ours is -8 male to -8 male), a tube sleeve, and a tube nut (both -8). For a hard-line to hard-line union, just substitute the hose end for a mirror image of the parts to the right of the union. Keep in mind when ordering fittings that, up until the regulator, you're using double the parts for one line since there is a return line. I got all my nickel-plated hose and hard-line fittings from Speedway Motors. | 
Since most trucks differ from one another, the stainless hard line needs to be bent up to fit, which can be a tricky affair until you get the hang of it. Order more than you need and don't forget to order enough for the return line. Using a welding rod as a template for some of the more complex bends can help. These pieces start at the top of the rear step notch and go down it and up the stock portion of the frame; I've tried to keep them symmetrical for good looks. I found that cutting the stainless hard line was easiest with a handheld cutoff wheel followed by careful de-burring before flaring. |

Here I am measuring for another section of the return line. From just under the rear of the cab, my boxing plates end and I needed to open up the space between the inside of the frame and the rear cab mount crossmember so I could run the lines on the inside. This also required a union in each line just behind the cab mount crossmember where my left hand is. Inside the frame is a great place to put Aeromotive's post-pump 12301 10-micron fuel filter. Aeromotive has clamps to help mount them, or you can just plumb the lightweight filter inline like I did. | 
Just under the driver side floor, my front boxing plates started again as well as brake lines. Therefore, it seemed like a good spot to install another set of 90-degree hose ends, which will run more braided hose up to the fuel pressure regulator that'll be mounted on the firewall. |
