Water seperating fuel filter - help

[MustRib]

Hello folks..
I'm sure John will be along in a minute to move this to the relevant forum, but
I'm looking for some help with an Eastern water seperating fuel filter I just got. I've made a quick sketch of the top of the unit, and numbered the feeds in / out. It was supplied with two blanking plugs and two fuel barbs, but no instructions. I'm a little puzzled why there are 4 inlet/oulets? So at the risk of being a total numpty, two quick questions...
1) Which connector for the fuel in from the tank and which one for the fuel out?
2) Should I be using ptfe tape around these plugs and barbs when I come to screw them into the housing?

thanks in advance
Andy

One of the main reasons for having 2 inlets and 2 outlets like you have is so you can choose which side of the filter you want both pipes to suit your layout. ie both on one side or in 1 side, out the other.

Connect your fuel inlet hose to either of the inlets and your hose to the motor to either of the outlets. Doesnt matter which as long as the arrows correspond with flow direction.

Dont think ptfe is fuel resistant, I use Hermitite red gasket compound for fuel line connections

You can use 2 outlets to run twin engines or main engine & auxiliary.
You can use 2 inlets for feeds from the main tank and a spare/reserve.

If only I had thought about it
thanks for pointing me in the right direction

I believe PTFE is unaffected by fuel; the reason they say not to use it is to avoid the threads cutting the tape into tiny threads, which migrate into the fuel system if the threads on the fitting extend through the threads on the base.

PTFE is fine, so long as you keep it away from the end of the fitting. If your unsure, then use a good quality thread sealent, such as loctite or similar, I believe they make a liquid PTFE.
