Just an FYI, PushLoks are designed to NOT be used with clamps, using a clamp cuts into the inside membrane of the hose, as the barbs are very sharp, because they are designed to be used with...no clamps.

PushLok is a Parker product, it is only supposed to be used with PushLok hose, the hose is special designed, somewhat like a Chinese handcuff, to grip the barb.

There is no Type A1 PushLok hose, most installations I encounter use common A1 hose with PushLoks, which technically are incompatible, and most have clamps, which again violates Parker's installation guidelines.

From Parker, "Note: Push-Lok hose is recommended for vacuum applications but not for cooling lines in air conditioners and heat pumps, or for hydraulic applications where extreme pulsations are encountered. Push-Lok is not recommended for any fuel." https://www.parker.com/static_conten.../4281%20B1.pdf

Parker does make a PushLok fuel hose, but it's not labeled A1, and must be used with HY fittings, which must be crimped.

Having said all that, I'll admit that the PushLok fittings are very convenient and make disassembly a snap. If you can find a similar flare fitting with a conventional barb, that would be better. I've never been able to pull any hose off of a PushLok fititng.
