Dorman800-011 Barbed Carbon Steel Union For 3/8 In. Nylon Fuel Lines, 2 Pack Universal Fit

These work perfectly. You must use a clamp to ensure continued security of line to fittings. I recommend you use the Dorman quick connectors instead (simply because of ease of use) - but these work as described.

It looks well built it's 2 small for my boats 3/8 fuel line, its just slack enough that I don't trust it for gasoline even with double hose clamps.

NOT BRASS! These are steel.

Only ran for less than 5 hrs stopped motor has no compression want to have it picked up

good product, reasonable price. allows me to repair air hose that dog chewed up. I used hay wire (SS) instead of clamps in case you were wondering, not really safe to use screw type hose clamps on air hose they always get loose.

Cheap and simple product that look strong and fit good.

I used mine for repairing a damaged fuel line in the Saab fuel system. Worked great.
