Quick disconnect, quick question?

[donandal]

I am hooking up my new fuel system for 5.3 LS in my
53 pickup. I am using the corvette style filter regulator
with quick disconnects on all three lines.

The fittings that came with the filter kit included the two
female ( 5/16 and 3/8 ) and one male 3/8 fitting.

while the two female fittings slid on and locked with a
high degree of confidence, the male slides into the filter
regulator much easier, and has about 1/4 inch of free play
in and out after passing the clips that hold it in. It also does
not have the internal plastic lock collars like the other ends
use. Just metal spring clip type fingers internally.

It won't pull out past the clips, but it has more free play than
I expected. Is that normal?

The other fittings have very little free play after they click in.

Thanks
