1998 Bayliner fuel starvation & pickup tube

[daschtick]

I have a 1998 Bayliner 1800LS with the Force 120 which seems to be running into an occasional fuel starvation issue. Sometimes the motor will just quit (usually at higher RPM), and when I check the primer bulb, it seems to be very soft, and sometimes partially collapsed. I also noticed that the bulb gets soft when sitting for several hours, and is somtimes difficult to re-prime to full hardness.<br /><br />Yes, I replaced the bulb, and the line from the tank to the transom, and now I am replacing the entire fuel line and bulb from the transom to the motor, with an OEM unit. I drained the tank, and it looks really clean inside. Any other ideas?<br /><br />Also, I wanted to remove the ball from the anti-siphon valve in the pickup tube (per 12footer), but I am not sure if I can pull the tube from the tank. The tank is a model FT2322, and it is a white plastic or fiberglass type of material. The fuel line is attached to a 90 degree fitting, which appears to be threaded into a permanent fitting on the tank. Will unscrewing the 90 degree fitting bring up the pickup tube? I don't want to damage anything, as it looks IMPOSSIBLE to change out the tank.<br /><br />Any help/ideas are GREATLY appreciated.<br /><br />-Nick

The "bulb" doesn't stay hard is normal being that it is on the supply side of the fuel pump and not the pressurised side. <br /><br />If the bulb is colapsing it is an indication of fuel restriction between it and the fuel itself.<br /><br /> Could be the pickup line, a filter, or just something it the fuel pickup then settling out after you shut the motor off till it happens to get sucked up again and cause the problem. Maybe just crumbs of crap in the tank??? <br /><br />Sorry just guessing outloud.

I think I’m having a similar problem with my 1987 Force 125. It looses power at high rpm like it’s not getting enough fuel. I thought it might be the fuel pump but I just replaced it. Try running the motor using an auxiliary tank, if you still have the same problem it would rule out your on-board tank. At that point you might want to look at the fuel pump, compression in each cylinder and perhaps a good de-carb.
