<VV> VITON SEALS AND GAS HEATER

[N2VZD at aol.com]

i have put in several viton crank seals etc with no troubles (that i know  
about).
i took one motor apart last year from texas area that had one weeping kinda 
 heavy. i suspect it was not lubricated properly...i always lube the seal 
and  surface with assembly lube as i put them together.
about the used gas heater: make sure you get the little fuel regulator that 
 is under the vehicle . it looks like a simple weatherhead brass 3 way 
fitting ,  but it has a spring loaded disk in it to keep pressure to the heater 
at @3#.  excess gas goes back to the tank thru that third line.
i think there are photos of that unit on the  website

also take that 4 way fitting from the fuel pump...or figure another way to  
supply , i used a 3 way in the left carb fuel line feed on one of my 
vehicles.  do your research on this project to save a lot of grief later. find an  
instruction sheet , and look at the service manual. you should plan on a 
rebuild  kit , (not cheap!) to replace old rubber parts that harden up and 
cause a fuel  shutoff problem, and a small filter disk hidden under a small 
brass input  fitting on the burner housing (a good test of you dexterity 
skills).
hope this helps.
i love my gas heaters!
