Fuel filter

Where do you guys think is the best place to put a fuel filter? Before or after the pump? I was thinking about putting a filter right before the pump on that rubber line that is only a few inches long. But I think it would be easier to put it after the pump. If I put it after the pump, I would have to replace the metal line with a rubber one so I can easily put one in. Is it OK to replace that metal line with a rubber one? Thanks for you help. I plan on getting my carb rebuilt soon and I want to prevent anything from getting back in it.

    The filter has to be before the pump, for if any trash gets in the pump it will hold a check valve open and the pump will not work. Also a good idea to install one before the carb. Walt.

    I have a metal can type filter back at the tank and a clear PVC type on the front inner fender before the carb. MAKE SURE IF YOU CUT THE METAL LINE AT THE TANK AND PUT IN A COUPLE OF RUBBER HOSES TO HOLD THE FILTER THAT YOU RUN A GROUND WIRE FROM THE TANK TO A GOOD SOLID GROUND ON THE BODY OR FRAME! The Hudson used the metal line as a ground for the tank. If you don't run the ground wire chances are that You Gauge won't work. Make sure to use rubber line to use fuel line that is compatible with todays new fuels.

    Maybe I should have one before but I only have a filter after the fuel pump and it's a disposable type...clear, and cheap enough.

    Do you guys think it is ok to put the filter on that rubber line right before the pump? The line I think is maybe 6 inches long.

    I think all the electric fuel pump manufacturers say to put a filter before the pump, and some say the warranty is void if you don't do so.

    These clear plastic filters in my humble opinion are OK for a lawn tractor,
    But, it is possible under hood heat or vibration could break one and cause a
    FIRE!.. I learned a couple cars with them burned last summer.
    I use only metal fuel filters, or the OEM with the glass bowl.

    Park is correct the electrical pumps require a filter before the pump.

    Also all fuel lines need to be under the car, not running thru the passenger compartment as I was suprised to find on my car when I inspected it.

    Nothing wrong with see through fuel filters as I have 3 on my car and change every 10,000 miles and drive across this country and back for a total of 10,000 or better, in 105 temp. Must use screw clamps not the ones that come with the filter, there is the problem. Walt.

    Where did you mount yours? I've been thinking right before the pump but I am now thinking it might be to close to the exhaust manifold.

    I have one before the electric fuel pump at the gas tank, one in the line going to the engine fuel pump, and it sit 3 inches from the exhaust pipe, and the other 4 inches before the carbs. Never had a problem. And as all know i drive across this country, S F to CT, 3,100 miles and do it in 6 days, and temps at times way above 100. I also started the fuel return line as this keeps cool tank gas going around in circles. Walt.
