plumbing fuel system

Which is the proper place to feed the fuel to the pump first or the filter first. Why I ask , my fuel feed goes to the filter first then to the pump and from the pump to the carb. but I see some of the motors here on oso are to the pump first.

Re: plumbing fuel system

Better after the pump to catch any little pieces that come off the pump diaphragm and keep them from the carb. Same holds true if it's injected-small metal particles from pump wear will booger up the injectors.

Re: plumbing fuel system

when i first put the motor together i had the ff/water sep after the pump. i installed a inline filter after the pump
filter
and moved the ff/h2o sep. to before the pump because i wasn't confortable with the can being pressurized with 15 psi(leak would be BAD). :D

Re: plumbing fuel system

Run A Filter In Front Of The Pump A Fuel Water Seperator Is Best. After The Pump Run A Fine Micro Filter (10) To The Engine Feed.this Keeps Water Out Of The Fuel Pump And Fines Out Of The Engine.
