Cummins fuel line

As always a pleasure doing business with Genos Fuel line arrived in a few days fit perfect was actually a better quality line than the old one because it had the isolater made on the line instead of the two piece factor design which is what caused line to crack in the first place! Very pleased!!

I replaced my original injector line number for before any problems ocurred. The new line fits perfect and is much sturdier! 10 minute install!

Dodge/Cummins made a design boo-boo on the original #4 fuel line, which generates a resonance that ultimately causes the clamping bolt to back out and the line to rupture at the most inopportune time. This is the redesigned Cummins part, and is a quick swapout. Buy one now if you haven't changed the #4 line out yet...because you'll need it sooner or later!

Well made, an improvement on OEM via the damper line mount. Arrived quickly and fit perfectly.

Great replacement!

The product I ordered was top notch and shipped extremely fast! Packaging was excellent, and I was surprised to find stickers and a magazine for my year model truck included in my shipment! Great customer service along with a excellent product, I will definitely be shopping with Genos again!
