Opinion needed on fuel pumps

[ScubaChief60]

After a few bouts of vapor lock, I installed a 6v electric pump on the fuel line just before the mechanical pump ( between the tank and the mechanical fuel pump). It is a 'flow thru' design electric pump so that the mechanical pump can pull fuel right thru it. I have it on a toggle switch under the dash so I can use it when needed. Its only a backup pump for when the mechanical need priming. Has worked great on several occasions.
