Universal M21, long story and fuel line question

[mikeg516]

My fuel pump is a Walbro 6000 series which appears to be discontinued. Does anyone have a better fuel pump option. The Walbro replacement is a FRB series.

OK! OK!

In this case---Last season the motor ran fine, this season a leak was discovered and fixed. Since fixing the leak the motor ran for a short time.......then quit.
GO BACK AND CHECK YOUR WORK ON THE SEAL AND MAYBE EVEN REPLACE WITH A NEW ONE--SOME TIMES NEW PARTS CAN BE DEFECTIVE.

Found a leak and fixed it. Now the electric pump gets resistence. Still have problems. I'm about ready to bring in a pro. My last attempt will include replacing all the clamps and a new fuel filter.

Barry... are you fixed yet?

I fixed my neighbors boat (86 catalina 30) this past weekend, with a similar problem. After getting him towed to his slip, we found that the engine would run with the bleeder open, and die shortly after closing the bleeder.

I inspected his fuel hoses. I found that the fuel feed hose was dry rotted where it turned a sharp corner in the bilge. It would suck air, but not leak fuel. He had been fighting this thing all last season, and just had "his engine guy" fix his run problem.

Hi,

I was able to fix my problem by checking and tightening all hose clamps. The engine now starts reliably and runs fine. I still want to replace the fuel lines because they are old and I already bought new hose. I need a few more odds and ends before I change things. Now I don't feel a real sense of urgency to change the lines, but I will change them soon.

Had a sorta similiar case of an air leak that fit both the "last thing messed with" and "old hoses will get you" answers. Mechanic putting in new Racor introduced a mysterious (to him) air leak. Turned out the old fuel hose from the shut-off valve to the filter had been beat up during the process and had developed a hidden crack that was sucking air but not leaking fuel. New piece of hose fixed the problem.

In a pinch you can leave that bleeder open until you figure out where the air leak is. I also had this problem on my 25XP. I replaced all the filters, all the fuel lines and still had the problem. I removed the pick up tube from the fuel tank to find that the brazed fitting on the pick up tube was cracked and that was where the air was getting into the system.

Boats are fun right???
