Questions & Answers

Is a perfectly straight/flush line required, or should a flared line be used? The rubber hose grabs a 3/8" pipe that has a small ridge. ?

It's designed for use with an efi quick disconnect, not a hose barb.

Is this compatible with the 5.9's 5/16 fuel rail? Is there a third LM7 engine?

No, it's for 3/8, but I believe they make a 5/16 version as well.

The safest way to upgrade from a 3/8 quick connect to a 6AN connector
5/5

If you want to convert a male 3/8 quick connect to a male 6AN, this is the way to go. The only thing to keep in mind is that the male 3/8 line should be as straight as possible. My fuel rail connector had a small bend in it that needed to be straightened in order for the two parts to line up properly. But, thanks to this and the Push Lock hose and fittings, I was able to build a fuel system that had no leaks the first time around.

When you re-create these, you'll be amazed
5/5

For an engine swap, you'll need to replace the fuel lines. When you re-create these, you'll be amazed. For an engine swap, you'll need to replace the fuel lines. The positive thread lock is a fantastic feature that gives me peace of mind that they will not come undone. They appear to be a huge improvement over the factory clips. The rings were well-fitting and simple to put on.

Transitioning from a GM 3/8" transmission line to an AN fitting was a breeze with this fitting. This was what I used to install a transmission cooler.

Russell's high-quality fittings are exactly what you'd expect
5/5

These fittings were used on my V8 swapped Ford Ranger build, which has been running smoothly for nearly two years. Russell brand products consistently deliver on their promises!.

But,,,,,,,,,,,,,,,,,,,,,,,, This connector does exactly what it says on the tin
5/5

The black coating comes off during assembly, which is the only disappointment I have. It's flimsy and can't withstand the torques.

Russell makes a fantastic product, but keep in mind that these are only compatible with factory style
5/5

Russell makes a great product, but keep in mind that these are only compatible with factory-style filters and not aftermarket filters. I was able to get it to work with my aftermarket filter, but I had to grind away nearly a quarter of an inch of material from the filter's nut to gain clearance. The item is fantastic in and of itself.

It works well and does not necessitate the use of any additional equipment
5/5

My GM LS-equipped vehicle was able to accommodate it. series truck fuel rail feed line, which works well and does not require any special tools, such as the OEM quick disconnects.
