1970-Cloned

I had a local shop crimp the GM style quick disconnect fittings on my fuel line and fuel tank. I purchased the Russell style quick disconnects to convert to AN fittings.

I am using a GM corvette regulator and filter in one and a LS2 engine. When I attach the Russell quick disconnects to the GM parts, Fuel Filter and the Fuel Rail the fittings snap on and won't come off.

On the parts that my local shop crimped my fuel line, the quick disconnects snap on and the o-rings fit really snug. If I pull back on the fittings hard they will slide back off and are not held on.

I am pretty sure the fuel lines will seal but under the pressure I am concerns with them coming off while driving.

Suggestions?

The lines should not came back apart unless you use a release tool on them.
The Russel fittings can be removed by pulling on the plastic release tabs, but correctly fabricated fittings will require the OEM style release tool. Do not use the fittings if they do not lock together!

Sounds like you need a set of these to release the first set of fittings. It's $10 well spent working on modern cars.



For the ones that aren't staying locked together, you may have a 3/8" female and a 5/16" male. These will NOT magically seal when pressurized! Regardless what she says, size does matter.

Something is WRONG do NOT use them.Or you will have a BBQ on your hands.

The only way they should come off is with the above tool.

I won't use these until they are fixed. It pisses me off that you pay a shop to do work and it is expensive. Rarely have I been please by work others do.

It is no wonder we outsource everything to China. The stuff is crap but at least you expect that for what you pay.
