adding a fuel filter to a 1650
 

I just rebuilt the carb on my 1650. I see the fuel shutoff valve has a screen on the end. Would it be advantageous to plumb in a fuel filter also? From the fitting on the carb and valve I bout 3/8" ID hose. I cant really find any universal filters that fit 3/8". The small engine shop around my house said that all air cooled engines run 1/4" hose. There is no way that 1/4" is going over these fittings. It had 5/16" on it but the hose was swelled out and cracked from I think all the pressure. So, what size hose is correct, and is it worth putting in a filter? If so, any leads on a filter?

IIRR those little red $2.00 B/S filters are for gravity flow and work well.
they sell them in Hwd,tractor supply & mower shops as well as evilpay.
I think I paid less than $2.00 for a dozen @ cutterschoice.com on sale.

those little B&S filters i think are for 1/4 fuel line.

And the screen in them has about the same size holes as the one in the tank inlet, so not much is to be gained by installing one, either.

I put a puralator fuel filter from Advanced Auto on my 1250. The parts guy looked through all of the filters until we found the smallest filter that would work with a 3/8 fuel line. Unfortunatly I didn't keep a record of the part number. I will try to check the filter itself tomorrow for a part number.

3/8" fuel line? These tractors generally had 1/4" from the factory. So I'm not sure how you got that to work unless you changed all the fittings.

It had 5/16 line when I dove into the project. The line was stretched over the fittings, bulged and cracked. The shank on tue fitting of the fuel shutoff valve was .412 I beleive. That is machined in one part so that size is unable to be changed out. The carb fitting is threaded I'm but I'd I can't change the shutoff valve what good would it do. I can force 5/16 back on but it will stretch the hose again. 3/8 seems big to me as my truck had 3/8 line on it.

Sounds like someone put a different petcock in the tank. You probably need to remove it a replace it with a stock one that uses 1/4" line. For my fuel filters, I usually get mine at the local green dealership. I just tell them I need a filter for a lawn mower and they give me one. It's clear and smaller than the kohler ones. I personally like them better.

This is the valve

it is the stock valve for the tank. I think it is the stock parts that is still on it. Looking at the other Valves for the x82 series it sure looks like a smaller hose

This is the valve for most of the earlier tanks

I can't reference the size much as I never handled one.

I have 4 quiet line cubs,1200,1450 and 2 1650's all have 3/8in. fuel line. They are all stock.
