Not enough room on low side AC recharge
I have a 1986 Porsche 928s. I bought a recharge hose with gauge as well as a can of R134a.
I found the high and low on the passenger fender side by the radiator. However there is not enough room to put it on the low side. To be clear I can get my hands down there, but there needs to be another quarter or half inch more space in between the radiator and the low side in order for it to slip on.
Any suggestions?

I had a shop rebuild a leaky line, and the converted me to R134a at the same. They but an elbow fitting on the low pressure line, which makes it fairly easy. I never tried it in its original state because of the leaky line.

The picture shows the high side connector and the cap makes me think there is an R134A connector under it. You don't want to try to fill from the high side, so you don't want to hook anything up to that except a gauge set. If that is what you want to do, you can gently bend the tubing up to the connector to get the fitting where you need it to be.
Low side connector is under the large radiator hose.

I'll see if I can tilt it up at all.

Hi, you do not want to ever fill from the high pressure side. I'm not sure it's even possible. You want to follow the thicker A/C hose to where there is a port with a blue cap on it. That is the suction/low pressure side of the system. Should be on the passenger side between the radiator and the engine against the side wall of the engine compartment. I think it goes under the radiator hose. If you hand doesn't get burnt attaching the fitting to the fill port, you're not doing it right! Ask me how I know! Good luck!
