    anyone wanna walk me through the installation of a mechanical fuel pump on my 318 in my 74 dart. I’ve never done one. Also do I need the 180 piece of steel hose coming off the fuel pump or can I just install a barb and use all rubber hose? Thanks. Using rubber as my steel line is in rough shape.

    As stated above, it’s your car so you can do what you want. There’s the proper/safe way and then there’s the good enough way. Using rubber fuel line is great quantities around a hot engine isn’t a great idea. Yeah a few inches over the entire run is need but having the line from the passenger side inner fender beside the engine all the way up to the carb being rubber isn’t the greatest idea.

      Barn won't fit, but an outhouse might.

      You can buy that section in steel pre bent.

      When you start to unbolt it and it feels like it's being pushed out on an angle turn the engine over by hand until it feels loose. This will put it on the low side of the eccentric and make installation of the new one much easier.

        yes, it will wanna go in at an angle. push it up against the arm and the bolts will line up, get them started and it will suck it right in. Small rubber from frames rear fuel line to motor pump, then from pump to carb is almost a full steel run with a filter in there as it moves with the motor. Its bolted down to the motor stock.
