[Fot] TR4 expansion tank question

[Jim Gray]

Fot,

I'm a little stuck on something. I want to install an expansion tank on the
car but from what I 

understand about them the bottom of the expansion tank needs to be higher
than the head.

I use a Griffin radiator which is lower than the thermostat housing.

I can't see a way to get the bottom of the tank higher than the thermostat
housing. 

I have my eye on a couple models Canton Makes but at best the bottom of the
tank would 

still be slightly lower than the top of the thermo housing.

Any idea's would be greatly appreciated.
