So I was measuring out a project
to install a T fitting in the fuel
line for my diesel
heater. T into the line between the tank and the secondary Racor's, and put a low pressure pump in that can fill a little ~3 gallon day tank which gravity feeds the diesel
heater. I can already see some problems in regards to the lift
pump sucking in air from the heater line, so maybe I'll do something else. Anyway...
There are two lines coming from my fuel tank
. One is running to the secondary fuel
filters (the Racors), which then of course lead to the primary, and on into the engine
Oddly, there is another line which is also running from the primary fuel filter
to the tank. There's no pump between the two, so I'm guessing it's maybe an overflow of some sort? Either way, just trying to figure this one out a bit.
Thanks so much!
