T&T: Electric fuel pumps

[Ron Rogers]

Most pumps are only protected by a simple mesh filter - on a few, it is not 
user replaceable. It is best to place the pump after the primary filter and 
your idea of being able to exclude it by valves is a good one.

| This has probably been discussed before, but here goes again. I plan to
| install an electric fuel pump on my DeFever 41 with a single John Deere 
engine. My
| only reason is to aid in fuel filter replacement, and I do not plan to 
have it
| running except when it is needed for filling / bleeding the filters Where
| should it go, and where can it go? On my previous sail boat, I installed 
it
| between the Racor and the engine filter. It seemed to work fine for many 
years, but
| I was warned many times that the vacuum required to pull the fuel through 
the
| valve on the electric pump would ruin my lift pump. (sort of like 2 micron
| filters ruining the lift pump, per the John Deere training Engineer). I 
can see
| that pushing might be better than pulling, so putting it before any 
filters
| may be best. Others have suggested putting in a "Y" or "T" with valves and 
only
| having it in the circuit and running when priming the filters. So, what's 
the
| experience of the group.
