Fuel Line Fittings

[702854boy 490]

Would anyone happen to know where I could get some fuel line fittings like the ones in the photo? Also would I need anything special like a specific type of line or flare putter onner?

Are you looking for all three pieces - the threaded fitting, the nut, and the soft sealing cylindrical part??

If you are looking for just the sealing parts, I have bought them in the past from Lowell.

The fitting and nut seem to be in good condition but the seals appear to be pretty cracked and the one fitting is able to slip off the end of the line so I wasn't sure what was needed to flare and reseal.

Lowell you gotta pay to be his friend. He's prolly got just the rubbers too.

That's not terrible for 10 Squirrelly. Bet they want another 30 for shipping tho. 

Best check with Handy Don & RI Bill to make sure viton is compatible with rocket fuel tho.  You know how they like to make lunar rovers out of GTs ...  just kidding guys sense of humor check just kidding ...

I spare Handy Don and RI Bill.
Yes, Viton is comparable with gas, oil, grease. It is an upgrade from conventional rubber.

$5.00 shipping is what it shows in my shopping cart.

I use a cheap tubing bender and hardware store compression fittings.

The only possible issue I see happening is fatigue cracking from vibration using these. Perhaps that is the reason for the soft seal??

FYI - the ones I bought appear to be made of 3/16 (5mm) automotive fuel injection hose....

Because the pump and carb are both solidly mounted to the engine I don't think that would be a problem. Being compression fittings there's no rubber seal for the fuel to attack. I did that shortly after I got the tractor at the 2018 show and it's been fine. That 854 is dedicated to the sickle mower so a breakdown is nothing more than a nuisance but I'd likely still go electric if there was an issue.

I have a few for the bigger engines eight and up. They’re a little dirty, but they could be cleaned out. Let me know if you want them. I’ll just send them to you. You’re also gonna need the little rubber grommets on the end. I believe I have the part number for that.

Thanks for the “viton” assist @oliver2-44!

Separately vibrating components would be connected with a flexible hose or tube.

 

The vibration being guarded against is the vibration of the unanchored tubing itself within the compression fitting across all the frequencies the engine can sustain. Yes, you might do it and never have an issue, but the best practice (as demonstrated by Kohler using them) is to use anti-vibration fittings like those Lowell is selling ($15 a pair). 

[Racinbob 12,747]

Wheel Horse used those fittings 60 years ago because it was what was used back then. It had zero to do with vibration of the unanchored components and Kohler never intended it to do so. Rest assured, compression fittings will do just fine. They just aren't 'factory original'.
