[TR] TR2 gas line/float bowl question

[Angelo Graham]

Hello List:
Sorting out issues on my '2 project and having a bit of a problem with 
the banjo fittings on the float bowls. I'm still using HS4s and they use 
a solid line and banjo fittings on the bowls. I am using the fiber 
gaskets on either side of the banjo fitting, but because of 
over-tightening the large bolts, I can't get the fittings to stop 
leaking. I must have totaled the fiber gaskets, but they still look OK.
Is it possible to use neoprene 'O' rings on these banjos? There must be 
something better than the fiber gaskets that came with my rebuild kit.
Thanks for any help with this.
