Inline fuel filter for a ford 640

What's the simplest way to put in an inline fuel filter on my Ford 640 and bypass the glass bowl filter? Anyone who has done this and has experience with it, I would like to hear from.

Thanks,
 
And what is the problem with the filter (screen) on the shut off in the tank, the filter (screen) in the sediment bowl, and the sediment bowel it's self?
 
There is no need to open that can of worms. Simply clean and properly maintain the OEM sediment bowl.

If you MUST do so, be CERTAIN to use an inline filter intended for use in a gravity flow system. Most aren't.

Meck, When I bought my 640, I was determined to do just that. Being around all sorts off engines for over 40 years, I couldn't imagine a vehicle without a real filter. Found a filter that was usable, flowed real well just with gravity. Tried my darnedest and thought I had success multiple times. Nope.

The challenge is that the tube needs to be at a fairly even downward angle from the tank to the the carb. Ran the tubing all different ways. Still...nope

As always when the filter question comes up that myth is kept alive...

xactly, Hobo! Just take a new filter from a high pressure FI system and gravity feed it. It flows freely! BTDT.

The problem is and why in-lines get a bad rap is the fuel tank is contaminated no true filter will live very long. Clean rust free tank clean fuel then an OEM strainer (is not a filter) will do just fine.

A contaminated system will win every time OEM are add on its a bet you are not going to win its old and tired get rid of the contamination life will be good...

Show tractor, on a real working tractor that's a fire that hasn't happen yet.
Growing up I remember the exhaust manifold on our 850 glowing red/white hot, a plastic fuel filter that close to the manifold would have melted dumping gas on a hot engine, POFF.

(quoted from post at 14:02:16 05/04/20) What makes us think we are smarter than Henry Ford.
on't know about that 'smart' part, but when that tractor was 70 years younger, I doubt that it had a rusty gas tank.
 
Am I smarter than Henry Ford? Hardly. But Ford s greatest accomplishments were 80 100 years ago, and there s been a lot of technological improvements since then. The same goes for reinventing the wheel. I d hate to be driving around today on the wheel as it was first invented.

As for you who replied with constructive comments, thank you, especially to JMOR for posting the picture. Very useful. But wait! Is that a spin-on oil filter that I see on the tractor instead of the original? What in the world will be said about that?

I m 73 years old and have owned a bunch of cars, trucks, tractors, and you name it, and I ve done the work on all them. There s not been a one that couldn t have had something on it engineered better. It never hurts to look for ways to improve whatever we re working on.
