Fuel Filter

[aero3113]

I took apart my carb to check the float height. In the bowl was alot of debris (Looked like very fine rust colored sand. I am sure it is some rust from the tank). I have one of the glass bowl fuel filters that I am thinking about installing. Do they work well or should I put in a modern inline fuel filter. I took apart the glass bowl filter and I am confused by how they work.It looks like the debris can flow right over the filter into the carb.

Which glass one do you have? Carter AC etc? A lot of them you can get either a new stone filter or a modern paper filter to go inside. Not sure how they work but I've heard they filter well.

I do not have it with me but I think it is an AC. I know it has a paper filter.

IOn my 39 Desoto I installed a fram inline plastic gas filter. I like these becasue I can see if the filter is getting dirty and any sediment will drop to the bottom of the filter.

I was able to purchase several of these at Hershey this year for a buck a piece. Every year I install a new one at that price. Evey at a couple of bucks from Walmart this is real cheap insurace for the carb.

If you had coated you gas tank with the older sealeant material i do know that this now starting to flake off and has been causing some issues.

Also If you have an electric fule pump at the back of the car I would also put on a filter to help catch any sediment prior to going into the filter.

Rich, the only thing that worries me about the plastic fuel filter is if they get hot,crack and leak, especially if used right over the exhaust manifolds.

I have both the metal in-line filter right after the fuel pump, below the manifolds, and the Carter glassbowl type on the carb.

The glass bowl filter gets me a little leary since I have installed it, it has leaked a few times, I do n't completely trust it, even though the filter is in mint condition.

I have a new gas tank and lines, have not put a filter just after the gas tank, should I??

[aero3113]

If I use a modern inline filter should it be before the pump or after? My pump has a glass bowl with a screen,no filter.

[Young Ed]

If you are having rust issues with your gas tank I would think you'd want it before the pump and carb. When i had this issue on my car the filters were clogging quickly so I kept a spare one in the glove box. I eventually had my tank lined because it was too bad

[Jim Saraceno]

Young Ed is correct. I had rust problems in my fuel line and it eventually clogged my fuel pump.

Rockwood. I have the plastic filter inline just prior to going into the carb and this is sitting above the manifold. It is approx 5 inches above the manifold. I have never had any issue with it melting from the heat. If It did touch the manifold then I guess it would melt but it is not even close to the heat source.

Also if you are having a major rust issue then drop the tank and clean it an coat it. Also put a filter before the fuel pump to catch any junk.

Thanx Rich, no rust issue I have brand new tank, new lines etc....Fred

I have a decent length of flexible hose back by the tank. Can I install a filter there or should it be close to the pump?

Why not both, the area close to the tank, is whee I would go with the plastic, to see what is coming through it. I have a new gas tank, but think I will install a fuel filter near the tank too......Fred

[aero3113]

That's the same stuff that was in my carb. I guess it was from the tank if all of your lines are new.

I use an metal inline filter that screws in to the intake side of the pump. It was a ford

part # and I pretty sure I saw that trick by a forum search here.

Couldn't find the thread but found the part. Wix filter for a Maverick, can't beat the price of $3.69 :

Shel, do you have a part number for your clear plastic filter?

You don' say where the filter is leaking, but if it is from where the bowl meets the metal housing I may have a solution. The metal frequently warps over time and the bowl does not seat properly even with the proper gasket. A solution to this is to take the filter off and remove the bowl, gasket, screen and anything else that may be there. Get a piece of self adhesive sandpaper and place the bowl lip on the sticky side. Cut the sandpaper to the size of the bowl and then use bowl with the sandpaper attached to sand the metal casting smooth. Just keep twisting it 'round and 'round until the casting is flat. I was amazed at how much material I had to remove to make the seat flat.

I installed a Fram G2 fuel filter today. I put it back by the gas tank in front of the left rear wheel along the frame for easy access if I need to change it on the road. After about a 20 minute drive there was some of the rusty sand type stuff in the filter. So I guess the source of this stuff is mostly the tank and not the lines.

On my 47 P15 I installed a small metal filter between the tank and the pump on the upper inside of the frame rail, then hung my carter glass bowl off the carb. I did all this after a good acid bath and neutralizer of the tank. I figure the glass will let me know when the metal is full up on crap. Then I can replace the metal one for like 8 bucks and clean out the carter and back on the road. Easy to get to, easy to change and no heat problems. Good luck on it.
