Hey guys, tried searching but couldn't find an answer.

I was wondering if anyone has successfully used the Russell push-on fittings w/ the threaded retainer (PN#'s 644120 / 644110) on the corvette fpr? I only have one fitting from my fuel rail to test fit but it looks like the fittings might interfere with each other on the inlet / return lines.



I've seen lots of guys use the clip-on style fitting, but I'd like to use the threaded ones as they have a much more secure attachment. Fuel plumbing is not something I'm willing to take chances with.

Any input is greatly appreciated.

Thanks,

Chuck

No problems w/ the ones we've used.

I have had one pop off on my main fuel line and pour full fuel flow right onto my headers on my corvette. This happened on the highway and was one scary experience. I would never use one again. Now I use only swagelok fittings for this.

^^ exactly why I'm not using the clip on style.

This is how the threaded collar style attaches:



You'll shear the line before the fitting comes off.

I ordered the other fittings I need for it, we'll see if they fit.
