Fuel Supply Quick Connect Size?

[Lt. DMAX]

Replaced return line to cooler in the fall using 3/8" hose and 3/8" QC's from Earls. Now the return line from cooler to tank has failed. Need to access fittings at the tank top. I don"t want to drop tank in driveway. Tried removing the bed but 2 bolts spin and 2 bolts frozen so thats not an option. Research shows the drive shaft can be dropped allowing minimal access to connections on tank top. I wanted to replace fuel supply while i am ordering more Earls parts and the drive line is moved.

However, after extensive research, I am unable to find out what size the OEM connection is. The GM QC has a 1/2" note on it, but I can only find a 5/16" QC from Earls.

Will the 5/16 work?

Earls doesn't make a 1/2" but Vulcan performance does

Alex,

Thanks for the quick reply! I wish I had found these before going Earls! Speaking on a price point solely...

Do the Vulcan connectors function same as OEM requiring the tool to release or does the white clip allow for a hand to remove them?
