I have little room for a fuel filter in my '78 F100, and the inline filters always seem too bulky. Between the metal fuel pipe and the carb, I have to compete with the distributor, AC compressor plate, and the carb linkage for space. Also, all the fuel filters I see look pretty cheap. Are there any recommendations?
I normally use a metal filter housing. I'm using the clear Fram to evaluate some fuel hose I recently replaced. My fuel hoses along this segment are 5/16.
Pretty common problem, it's best to make a new steel line to move it up and shorten the hoses. but you can move it up higher with a longer hose on the feed side and use a metal filter they're normally a bit smaller.
You can also move your filter to the suction side of the pump, it's not as good since it will restrict flow faster than on the pressure side but if you change it when needed it works okay.
Why not put something on the frame rail where it's completely hidden away and there's no risk of a leak causing a fire? Fab up a bracket and mount it between two of the hard lines. You should probably R&R that soft line any way so this is a good excuse to do so.

Good idea, but I'm not sure where I'd put it. The existing gap in the rigid lines is directly above an exhaust pipe and really hard to reach. I changed the rubber hoses to 30R9 this past weekend, and it wasn't fun working in the area. I'm also reluctant to add an inline filter down there that requires changing. I'd have gas dripping down on me each time I do the work.
Maybe I'm thinking about this wrong. Is there a different type of inline filter that would have integrated shutoff valves and a detachable/replacable media canister? Something like the filters integrated into some mech fuel pumps?
I used a water separator/fuel filter left over from one of my boats, put it on the outside of the frame just opposite of the tank switching valve. Fuel lines go over the top of the frame.
I thought I had a problem with a tank, but turned out it was a piece of fuel line i used. It had been stored outside and earwigs nested in it. Little f**** fowled up everything.
That's pretty slick, Mark. I like the shutoff valves on each side. I'll get under the truck and see if there is a place to put something like this. I'd like to avoid cutting the metal lines, but that may be the only option. When I replaced the rubber hoses, I noticed the PO put a simple flare on the end of the segment from the pump outlet, rather than a bubble flare. I might be fixing that anyway.
I've never had a plastic fuel filter fail under the hood of any of my vehicles, at least from what I can remember... (knocking on wood now). I've had the glass inline filters leak. I think if your filter failed on the pressure side of a mechanical pump, you'd run out of gas pretty quick and the engine would stall before you would have a fire..my opinion. More than one old timer has told me inline fuel filters pre pump add stress to the mechanical fuel pump. So that's how I roll. idk.
Ive been pretty lucky. Ive used the plastic Fram type inline filters up near the distributor on my 70 f250 for a long time and havent had one foul up yet. It gets up to 115 here in the summer. If there is a problem though, it could be bad.
The manufacturers often use metal lines and devices on the pressure side of the fuel supply to discourage leaks and fires. If you use something else be careful about the installation and maintenance, and keep a fire extinguisher close by.
... I keep a couple on hand. I see they even have a chrome one, if it's not shiny enough. Wix makes a chrome one that Mr. Gasket sells too.
Once a pump pulls fuel through a sock in the gas tank, then pushes it through a filter on the way to the carburetor, I don't see any good from adding more filters along the way. Additional filters aren't gonna get fuel once the first one in line "stops up" are they? It's not like the fuel can bypass the "stopped up" filter anyway. With a larger fuel filter, then it will take longer to "stop up".
Pardon the plug wires, they are 8mm silicone, some hungry rodent chewed them 20-30 years ago, but I have new ones still in a box. Gonna put them on this Spring with new AP-25 plugs.
