Changing Raycor filter

[SCHUTZEE]

2000 31TE Cummins 450

I tried to change the element in my Racor primary filter today. There is no shutoff valve on the supply side, only on the outlet side to the engine. I wasn't able to stop the flow of fuel. The filter is lower than the tank, which is full. What am i missing? Do I need to pinch the hose off? Also, how do you remove the transmission oil? Do you use a hand pump or an electric one? I appreciate your advice.

It may be different on the 31 but on the 28TE there is a shut off valve near the top of the fuel tank. I close that when I open the top of the Racor or drain from the bottom. Russ

You are correct, no shut off valve. I put one on when the tank was low.

Also, I have to remove the filter housing from the bulkhead and tilt it forward to get the filter out. All in all, not an engineering masterpiece.

You could probably remove the supply hose and get the end above the tank, quickly, then put a shut off valve in the hose and put it back together.

ps -

I forgot to add that when I kept my boat in the frozen tundra of Maryland, general advice was to change the fuel filter in the spring after running some fuel through it.

Locking pliers will work in a pinch to clamp the line.

Haha. When I read this I did a double-take as I tried to picture a pair of vice grips pinching the 2" diameter steel-reinforced rubber hose that feeds our fuel system!

I have to continually remind me that we're not all talking about the same boats here.

If you have a 2" line running from the fuel tank to the Racor and then to the engine (which is what we're talking about here), you have an industrial size Racor and are burning some serious fuel.

Our fuel system recirculates the fuel as a method of keeping the fuel clean and filtered as well as keeping the injectors and fuel rail cool. The filter itself has a capacity of 360GPH, and I believe it actually pumps somewhere around half that.

I think you're right though, the fuel line going to the filter is actually smaller than the ones going to the day-tank. Still, it wouldn't pinch off with a pair of vice grips.
