<VV> Re: Time to Replace pump

[Frank DuVal]

Brass to brass is usually soft enough to deform and seal without any 
additional help. The steel nipple on the fuel pump may need some help, 
but the soft material it screws into may also deform to seal, as you 
have proven in actual use!

Teflon tape must be used carefully, especially the leaving the first 
thread bare, same as any pipe dope, or pieces will find their way down 
stream. It can also lubricate the fitting and allow female tapered 
threads to tighten easily enough to split when wrenched with strong hands.

Flare fitting should never need any additional sealing material. If they 
do, something is cracked, broken or worn out. So this nipple and the oil 
pressure switch are about the only places on a Corvair one could use 
pipe sealant. But it is not required.

And no, I do not wear a belt with suspenders, just plumb that way.
