T&T: Electric fuel pumps

[Carl H. Martin]

I've had an electronic fuel pump prior to the racors for about 4 years now. 
It's the square electronic type sold at Napa.  It's been very reliable.  I 
recently used it to pump 40 gallons from the port tank when it developed a 
leak.  It makes it very easy to change filters.  You can also turn it on & 
keep going, if you need to, when a filter starts to clog.  In my experience 
there is no reason to T it off the main line.

Happy cruising,
Carl
