<VV> VAPOR LOCK

[N2VZD at aol.com]

Only time I had a vapor lock was only a year ago on mothers day. It was HOT 
 out , drove @65 miles at speed , shut it down at a Restaurant , came back 
out  and started right up , pulled out into fast moving traffic , got about 
1 mile  before it quit. I finally got it going again by choking it. The fuel 
pump was so  hot you could not put your palm on top without burning it.
I have since added a 4 inch fan by the motor mount aimed at the pump. I  
doubt it is a big help , but no more trouble. I did check pushrod length when 
I  worked on it the next day , but checked ok. I have found a short pushrod 
years  ago that apparently caused strange hot run issues on a friends 
corvair.
 I feel we are more vulnerable to vaporlock and other problems because  of 
the "new improved? gas"
I have made a "test" fuel line that replaces the left carb feed with a line 
 made up with a T and a small  fuel gauge . I usually use it on my new  
rebuilt motors  along with adapta bolt oil pressure gauge until ready to  
install in a vehicle.
