Good seal with Thermo quail?

[bluesman31]

I have an older Thermo Quail and it does not seal well. The hinge seems to have loosened up and even with a new red top gasket it does not create a tight seal.

I have a Boyce Motometer on another car that fits with precision nice and tight

Is mine just worn out or is this just the way the design is on these quails?? Is this a typical failure point?

What's leaking?? There is another gasket UNDER what the quail attaches to. You could also try double gasketing under the quail cap.

I have used gas gauge shim washers under the gasket along with some silicone sealant to hold everything in place. Seemed to work OK, ie: no leaks.

My quail cap was leaking too, so I used a 2nd gasket and (knock on wood) no leaks so far

I use a big O-ring.

I'm with BarracudaBoy. I went to the hardware store and found an oring that looked like the gasket. Put it in and hasn't leaked a drop.

I think so my motometer started to leak last time out i checked and found the same loose top i will try fresh gaskets first than move up to a big fat O ring

O ring from harbour freight fixed mine.

The big suppliers sell a very thick o-ring to go under the top half for worn out hinge situations.
