Goodyear GY1100 floor jack

[Patrick0525]

Can someone post a pic of the fill plug from the rear view? I need be absolutely sure which is the fill plug for the GY1100 floor jack. I don't want to open safety valves accidentally.
Thanks

This is a 1.5ton racing floor jack sold at Pep Boys and other big box stores.

I have the feeling one factory makes about 90% of cheaper knockoff jacks.

Logically, fill plug is from the top.

I can be wrong though.

There is no fill plug on the hydraulic ram body tube. Most floor jack's have this obvious feature. The GY1100 has three screws on the hydraulic unit base . Two are the safety screws and other is the fill plug. Goodyear could have done a better with their labeling.

It doesn't look this and it has only three screws and one plunger and not two.
The back of the unit is on the right-hand side. Based on the Harbor Freight PDF link, my guess is the fill plug is the left most screw since other two are closer to the internal hydraulic circuit. Since most floor jack's have the fill plug on the main tube, this left most screw is closest to it.

Also, it looks like the safety valves are aligned on the same vertical axis. It makes sense that you would not put a fill plug port between two safety pressure screws and potentially cause a weak point aka a leak.

Amazing for a Memorial Day weekend.

They said it was the screw hole closest to the ram tube.

Thank you Kevin!
