Water seperator for a 2 stroke and a 4 stroke auxillary motor

[starjet]

Does anyone know if you can run two fuel lines thru the same water seperator. I want to hook up my main 2 stroke and an auxillary 4 stroke trolling motor. Do I need two seperate filters?

Maybe a dumb question but one line will have oil in the gas and the other line will be straight gas.

Does some opf the oil stay in a filter when a 2 stroke fuel goes thru it?

The filter will not filter out the oil.

You can not run 2 types of fuel into one filter, and expect them not to mix.
They will mix. You will have oil going into the 4 stroke, and not enough oil going into the 2 stroke.

One of the benefits of running a oil injected two stroke

So what you're saying is I need two seperate filter systems. I don't understand how oil mixes with the 4 stroke if the two stroke is off anf the 4 stroke is running off of a seperate gas only tank.

Ayuh,.... When ya switch tanks/ motors the gas in the filter, will be the wrong gas,...

The 4 stroke will smoke til it burns off,...
'n the 2 stroke may well seize, before the mixed gas displaces the straight gas,...

also you weaken the back-up aspect of the smaller motor. Often motor failure is caused by problems in the fuel path, including a clogged or water-logged filter. Since you have to run two tanks anyway, spending the extra $15 for a second filter is worthwhile to keep the two systems independent.

Since I'm human and I must assume you are too, Star, we make mistakes. The mistake to be made here is forgetting to switch tanks when going to the kicker and vice versa. Straight gas mistakenly running through the main 2 stroke will have you coming back here with questions and no good answers.

Spend the extra cash for for two separate water separators.

If you buy good quality fuel and consume most of it throughout that outing, no need to install a water separator filter specially if boating with small to medium portable engines. In the long run could develop fuel pump diahragm stress issues, due to being thin made and with more pumping work than without a water separator filter. Never have used one and don't plan using one.

The 4 HP engine probably has an internal fuel tank and can't possibly install a water separator filter ?
