    Hey guys I have some more questions for you. I have a 440 with an Edelbrock AVS 800 cfm. I’m running 3/8 fuel line from the tank to the pump. Right now I have rubber 3/8 line from the pump to an aftermarket vapor separator with 3/8 inlet/ outlet and 5/16 or 1/4 return (don’t really remember which). From there it’s a rubber 3/8 hose into a mr gasket pressure regulator and pressure gauge before finally getting to the carb. I want it to look a little more stock and clean.

    1) Does anyone know where I can find 3/8 carb to pump preformed lines?

    2) If I can’t get a preformed 3/8 line, will it be okay running stock 5/16 from the pump up to the carb?

    3) If I use stock 5/16 preformed fuel line, does anyone know where to get an adapter fitting for the stock line to connect to Edelbrock carbs? The stock line fittings work on Carter carbs but not on Edelbrock carbs.

    I would Check with Roseville first they will know if & where to get the preformed lines & can supply them as well . Home | Roseville Moparts
    I believe you will be OK with 5/16 line to the carb but it depends what you are doing , I found around the 600 hp & 12 second 1/4 mile the 5/16 line become restrictive .
    I never run eddy carbs ,a fitting shop might be able to get something to work , not sure what the threads is into the carb body though & you will probably find the hole through the fitting is only 1/4" , a 2" long hose connection may be the best bet .

    I would suggest making your own 3/8 fuel line from the carb to the fuel pump. It is not that difficult and the tools can be rented for free from some auto parts stores.

    Thanks for the help. I think I’m going to do a stock 5/16 fuel line with a fitting I found that might work connecting it to the carb. It’s a 5/8”-20 x 1/2-20.

    I have to think Chryco is right. I run the stock 5/16 from the tank on a 73 cuda.
    Pump to bb six pack is 3/8 and does real good for mine.
