'49 H Inline fuel filter

FarmallJon · May 26, 2011

I'm putting the H back together after I took it all apart to restore it. The inside of the tank was a little dirty, so there is a small amount of crud still in there even after cleaning it out. I was thinking of putting in one of those clear plastic in line fuel filters to catch any crud that gets by the sediment bowl. Will this work ok with a gravity feed system, or will it cause problems due to restricted flow?

Many people will try tell you otherwise, but I know from experience that in-line fuel filters work fine with gravity feed systems. I got my 140 with an in-line fuel filter, and have kept it that way. The only downside is that the filters must be changed often. If your tank is really dirty, it may be more trouble than it is worth to install one. You may be better off cleaning the tank again. But, if there truly is only a little bit of crud in there, an in-line filter will work fine. In fact, if I were you, I probably would install one myself!

PS: There is a strainer in the carb that will become clogged with crud eventually, so it will be better to have the junk caught where you can easily access it (the in-line filter) than in the carb.

I think you will be most satisified if you stay with the original sedimate bulb type strainer and filter rather than a modern type inline filter. Most inline filters are designed for pressure systems rather than gravity feed.

I have a 49 H with an inline filter added, it works fine.

In line filter can work ok for a while and then cause you so many head aches that make them not worth it. If you get one made for a gravity flow system maybe but then the sediment bowl system has worked well for over 50 years so why mess with what works already plus one less part to worry about. I have been payed at least 30 cases of beer to throw away in line filter problems. Yep that is what I charge to fix that problem

The factory designed system worked OK for half a million tractors times 10,000 hours. That's 5 Trillion hours. Sediment bowl filter and and carb filter. If it ain't broke, don't fix it.

Steiner tractor parts has a standpipe type filter that fits on top of your sediment bowl assy. you unscrew the assembly from the tank.it is a swedge type fit.goes in the opening in the top of strainer assy.it is a fine screen. have one on my 43 M,works great. Jim

I got inlines on all my gas tractors-works fine-just bleed the air out before hooking up to the carb.Catches the fine/powdery stuff that gets past the sedement bowl.

You will get a thousand different answers for this. The best thing to do would be to strap the gas tank to a tire on a tractor a drive it around for a while with some old bolts in it or rocks, clean all the crap out and put it back on. then you don't have to worry about it.

My vote is for No inline filter.

A gravity feed fuel system operates at low pressure. Moderate restriction caused by a fuel filter can reduce the fuel pressure to a dangerous level and cause a lean the air/fuel mixture. The air/fuel mixture needed for combustion may not be enough to keep the combustion chambers cool while operating under load. If an engine is running so lean that the piston and chamber have heated up more than tolerances will allow, the piston may grind against the cylinder wall until it freezes. Excessive heat can burn a valve or melt a hole in the piston.

It would be interesting to find out if melted pistons are a common failure in IH engines?

Theres nothing wrong with a sediment bowl, IF the screen is in tact and in good shape, not much will slip by it, and what does will catch in the carb filter, BUT I have inline filters on 2 of my tractors, ones a retired working tractor, the other is my working tractor. I have used them VERY succesfully for years. Yes they get dirty, yes they do eventually clog, but they do what they are suppose to do and Im fine with that. If your doing this temporarily, you should be fine. If you want to leave it, you should be fine.

IMO, it's not restored if you do that.

FarmallJon · May 27, 2011

is it fairly simple to check/change the flter in the carb? Is it in the inlet port? What's involved?

My 1940 H had a BUNCH of rust and crud in the tank when I bought it. I was able to get some of it out, but not nearly all of it. Basically, it was still a total mess inside, but I put that tractor to work anyhow, and the sediment bowl caught all of that crud. I had to clean it out about once per week at the start, and now, 10 years later, I clean the sediment bowl just once per year. NONE of that rust and crud EVER made it into the carburetor. NEVER had to take the carburetor apart to clean it.

if you need to run an inline filter, go to your napa auto parts and get either a 3031 or 3032 in line filter. it is a metal sealed filter designed for a gravity flow system. your filter selection will depend on your fuel line size that you are using.

I have used them for a long time only problem is they will catch fines that get thru the brass one in the sediment bowl assy and get plugged and after a few changes enough seems to have been out of the tank. i mount them so the outlet is pointing down towards the carb. They sure do their job well.

Haas · May 27, 2011

Glennster has it right. Go to NAPA and get a number 3032 filter. It has a metal case and is made for gravity flow. I've used them for years without a problem.

As for cleaning the tank,
I used some stuff called EVAP-O-RUST I picked up at Tractor Supply, easy to use, washes out with water, and removes most of the rust, just pour it in, let it soak a day or two, drain it back into to jug, wash the tank out with water, dry with compressed air.......rust WAS gone !!

I was skeptical, the last tank I did was on an F20, took it to a shop that specializes in fuel tanks, can you say cha-ching!!! This stuff isn't cheap, but it was a heck of a lot cheaper than taking it to a tank shop.

This stuff really worked.

Yes, it is easy. Yes, it is in the inlet port. You unscrew the fuel line and it is the big brass thing right next the the carb. The biggest PITA is trying to get hard metal line lined back up with the fitting. I would spray it off with some carb cleaner and put it back in.
