this is what I'm going do on my gt4, bit of braided hose into a block with a hole for each sensor  might do it on the Glanzlet too as I've a bag of guages LOL 
   
 I was also advised not to put the t-peice into the head directly as it can snap handy, that's what the braided hose is for. Can hide the sensors away then as long as they are secured well
