fuel line question

whats the standard size fuel line. I mean like is it 1/4 3/16" 5/16

i need a new one for a lawnboy commercial lawnmower 2 cycle engine. don't have the model number at this time. heres a pic of the mower. the old one is ripped off at the tank and won't reach so it can't be repaired.

The standerd 1/4 ID X 7/16 OD black line, like goes on B&S or Tecumseh will fit or if there is any of the old fuel line left at all you can measure how much you need and take it to your local small engine shop and they can match it for you.

so a role of 1/4'' clear fuel line would work.

I'm not familiar with this model but it should be 1/4" (ID) but i've seen some Lawn-Boys with 3/16". Based on the fact that it is a "commercial" mower, I'd go with the 1/4". Yes, clear line will work but braided is better. I like Tecumseh's fuel line.

With a hose clamp that you can tighten down you could probably get away with 1/4" id fuel hose on a Lawnboy, but 3/16" ID line is what you should really be using on a Lawnboy mower.

Ok not sure if it helps but heres the model number 8481AE SERIAL F195BO147

yes it is a commercial lawnmower made for commercial use based on the fact that its a 1 gallon gas tank electric start only grease fittings for a grease gun also it has a 20 inch aluminum deck

Half of 1/4 is 1/8. That's not the size of the fuel line on your mower.

It uses 1/4 in black rubber fuel line like the B&S and Tec's. I think that is a commercial grade mower but not a true commercial mower or it would have an orange tank and red wheels and have a bush guard in front of the engine. Have a good one. Geo

The inside hole of your fuel line? That's tiny...more like weedeater fuel line. I don't think I've ever seen 1/8 fuel line on a lawnmower.

Sounds like you might be referring to the primer hose?

no this line goes from the tank to the carb and is broken off. the outside is about the same if not slightly smaller then a standard fuel line

I'd recommend going to your local shop and purchasing short pieces of 1/8", 3/16" and 1/4" fuel lines and see what fits up.

I checked my gateway cd and it lists 3/16 ID fuel line for this model as well as most all others that I glanced at while I had it out and was checking too see if I could find any models that listed 1/4" line. I am sure you could use 1/4" line as long as you use a screw type hose clamp that will hold the fuel line tight.

ok removed the old fueline. the opening is 1/8 the outside around 1/4 as the walls are 1/8 thick. but the carb and fuel tank nozzles are 1/4 big so I need a 1/4 OD fuel line correct.

The fuel line should be slightly smaller then the fuel fitting to assure a snug fit that will not leak. 1/4" fuel line should work just fine, as long as it's clamped snuggly to the fitting.

Uh flirty that's larger then 1/4" by 1/16" of on inch.

1/4" would be the same as 4/16".

3/16" would be 1/16" smaller then 1/4" line.

1/8" is 1/16" smaller then 3/16" or is half as small as 1/4" line.

When we are referring to the size of the fuel line we are all talking about the inside diameter "ID" not the outside diameter "OD". The only time the outside diameter is going to be an issue is when it needs to either seal through an opening or has a limited amount of space it can fit in.

If you don't need 25 feet of fuel line, you can pickup 1/4" ID fuel line at any auto parts house and just buy the length you need. You should be able to get what you need for less then $5.00

Just in case you don't really want a 25 foot roll.

I/We are not concerned with what you have, we are concerned with what you need to replace the current one to solve your fuel line problem. The photos are to illustrate one option that will work. Also, if your mower is a Commercial grade it will have a plastic carb and a tapered fuel inlet so several lines will fit. It is Commercial it will have a metal carb and ridged fuel line asccess from the carb and is not so ascessable. Have a good one. Geo

easy there temper temper. you posted picks so I replyed you should explane yourself better. anyway yes the carb is metal the old fuel line had a rib going across it yes its hard to access the fuel line but I got it off the carb nozzle is tapered along with the tank nozzle. no primer on this model. I will order 1/4 fuel line unless you know of a size smaller that would work as the nozzles are 1/4 big. if 1/4 line is fine then this thread is solved unless it doesn't start.

No temper,temper, I am just here to try to provide a solution to a problem that if taken to a service center will cost you appx $65.00 per hour after the initial diagonistic cost to $89.95 or whatever. However we can't help you if you don't help us. The pic's show your tank with fuel line attached, the fuel line size, specifications and manufacturer. Thats about as good as I can get. Have a good one. Geo
