Fuel draining out of Racor - Bob Lawrence - 11-21-2007 17:43 Hi group, We are finally on the road fulltime and have just left Death Valley. The bird wouldn't start and I noticed the clear bowl on the Racor only had 3-4 inches of fuel in it. Upon removing the filter to see if clogged, I could here fuel, glug,gluging into the bowl. It didn't add an inch before not gluging any more. I blew thru the filter and fuel came out top to bottom of filter which told me filter wasn't plugged. Put filter back in, added ATF to fill the filter and it started right up. Fuel is draining back to tank. Is the fuel pump going bad? Only thing I can think of. What say you?

Added one to my FC at the pusher pump inlet and life got a lot better. Put one on the gen set one on the diesel boiler too. Idea is to stop drain back at fuel inlets, you have practical experience on how that is a bad thing. Fuel injection shops will have them in stock.

I was able to blow fuel back into the tank and then re-prime the fuel line by pressurizing the fuel tank slightly (leave the lid on the tank filler neck). To the best of my knowledge, there are no check valves in the system, except the small aluminum alloy ball in the bottom of the Racor unit. You should clean that by removing the bowl assembly and unscrewing the flared plastic fin assembly that creates the centrifuge flow in the bowl. From what you have listed, I'm guessing that there is a clump of sludge, rust, etc.. somewhere in the fuel line that you were able to dislodge. If you are losing prime to the tank, then one of your Racor's o-rings or seals around the bowl and cap are leaking. You could also have a slow leak in the fuel line connections around the secondary spin-on filter and/or low pressure fuel pump connection. If you've never replaced those lines, it may be about that time.

Yes, I had sludge in bottom of filter on the flared fin assembly. Had taken the bowl off, cleaned it up, removed the aluminum ball out. Filter was plugged with junk. Put another filter in, drove 200 miles and filter was fine, but the fuel drained back to tank. I'll check the secondary spin on for leaks...didn't notice any tho. Mike, your idea of adding a check valve is a good one...will look into adding.

But air can get in without fuel getting out if the circumstances are right.
