32 Dominator
 

My friend has had a 95 32 Dominator with 502 efi mags for 10 years. If he idles for a while then cuts it off for a few the motors are vapor locked and will not start unless you bleed the fuel rails then they start right up. Different shops have added fuel punps and vent blowers but did not help. Any sugestions? I was thinking changing the 160 thermostats with 140s. Thanks.
