Fuel filter placement question

I have two of the plastic fuel filters routing to the carbs (after the stock fuel pump) in my engine bay. I want them out to reduce the fire potential.

I am thinking of putting a single filter under the fuel tank but I wonder if this the pump will be able to do its job.

Also, anyone not running a fuel filter at all? I am thinking of adding a new bigger fuel tank and coating the inside of it with POR-15. Maybe I don't need a filter at all if I go this route.. Your thoughts? Thanks in advance.

I would suggest that you change nothing except the filter themselves. There are metal filters that will fit inline in the same manner, and that are far safer.

i had a filter under the tank before the electric fuel pump and another one by the firewall but not on the engine side of firewall.

Thanks guys. Lane, I assume you are talking about this type:

I was under the impression that some of the problems with fires starting at the filters in the engine bay is the connections themselves. Filters weighted with fuel and vibration causing them to work loose... But this might just be hype.

my fuel filter is the plastic one and it's under the fuel tank.

i'm running an electric fuel pump though.

i wouldnt run a fuel filter in the engine compartment - but that is just me. why risk it?

what about above the front of the tranny where the line comes out of the frame horn?

Nah, mine aren't that fancy. I just get 'em at the local auto parts place. I'll see if I can find a part number or take a picture.

I have an electric pump, and have one filter between the tank and the pump and another one in the engine compartment before the fuel line splits to the two carbs. They're both the same type.

I really, really like one of these mounted below the tank and ahead of the pump:

Yeah, I like that one too, Gordon. Considered it, but never bought it. I have a Ford type screw-in. Do you remember the ones that screwed directly into the carb? That style(metal) is screwed into the inlet side of my electric pump.

I am going to look at the frame horn area and see. I guess I could always run an electric pump and that opens up more options.

Mine is up front, before the pump. It's in-line, has a stainless series of screens inside and is easy to clean.

It usually works best to have a secondary in-line filter that you can replace easily. The down side of having a small micron filter in the tank is that when it plugs, it's time-consuming to change, hard to diagnose, etc. There are no easy answers, but a plastic filter in the engine bay or near hot metal is dangerous. Besides, in-line filters are cheap. Write a memo on your garage calendar to change your fuel filter when you think it's appropriate, say every 6 months or so, depending on usage, fuel contaminants in your area, etc. If you use rubber fuel line, use quality ss hose clamps, and check for leaks after a swap.

I've always liked having my fuel pump and filter under the gas tank. That way, if there is a leak it won't cause a fire.

Placing one between tank and pump should be "standard" procedure..... As for diagnosis of a plugged filter....Its not as easy as might be expected..... I chased an apparent carb problem for 3 - 4 weeks, redid the secondary ignition, only to find that the new Wix filter I had installed had collapsed internally.... S%&T happens.... I now run a 5 micron filter behind the left rear wheel area to keep the tiny kids and dogs out of the carbs....
