  • looking for ideas for different AN fuel line routing

    looking for ideas or suggestions on redoing my #8AN fuel line set up from the regulator to the carb ,i'm looking at going back to this style set up in the 2nd pic . the problem i had was the lines were touching the valve cover and it was hard to pull the AN lines apart at the bowl fitting on the carb . Could i use a 45 or 90 deg fitting at the float bowls or ???


    this is how it is currently ...



    this is how i had the 8AN lines run up until 3 or so years ago ....

    This is how I mounted mine on my BBC for the '71 GMC. I made the bracket myself out of some 1/2 plate aluminum.

      How about putting the regulator on the firewall and feeding the carb from there, with 90 degree fittings on the float bowls?

        Apparently mounting regulators on firewalls is an NHRA no-no.

          Same goes for the isolator for a fuel pressure gauge. Also in his pic it looks like he's got a fuel line running through the firewall into the passenger compartment, that is a big no-no to.

            I would bet that line goes to a cowl mounted fuel pressure gauge.

              Let's hope so.

              In the bottom picture it looks as if the small line comes up through the cowl just in front of the windshield.

                fuel pressure gauge mounted on cowl panel outside of passenger compartment

                  just trying to keep it looking late 70's early 80's so i can't use any of those cool looking CNC brackets/mounts

                    *And steel braided line is considered okay to cross the fire wall.

                      I am at 27 years OEM build through the chassis.. along the rocker inside the car. No steel braid through firewall.

                      Local, the dangling fuel lines outside was as dumb as the brake lines. Shame on NHRA.

                      I like the regulator, dual output, then to carb.. however that gets worked in, seems smarter.

                        Why not use a shorter carb fittings?

                          i've got that style fitting in 8AN with 7/8"-20 thread but once you try and connect a fitting to that fitting the lower r/side bowl screw will be in the way and you can't thread it on .This is why i also bought the Russell #640210 bowl fittings like in the 2nd pic as it is 2" long and doesn't get in the way of the bowl screw

                          Don't understand why the description of the shorter bowl fitting which is 1.2035 inches long and 7/8"-20 thread interfere's with the bowl screws and you can't put another fitting on it


                          this is the bowl fittings i've got ... http://www.summitracing.com/parts/rus-640210/overview/




                          these are the shorter 1.2035 long 8AN 7/8"-20 thread i also have but as i mentioned they're short enough to interfere with the lower float bowl screw when attaching another fitting to it

                            pics of the different 8AN 7/8"-20 thread bowl fittings ..


                            1.2035 inch long 8AN bowl fitting ,notice the interference issue with the float bowl screw




                            2" long 8AN 7/8"-20 thread bowl fitting ,notice no interference issues

                              IDK ... I always take the fitting off before I remove the bowls and never have a problem.
