Engine shutting down
It seems the carb is running out of fuel after about 5 mins. Also we need the choke on for while longer than usual, more so when the engine was cold. . After the engine dies we will pump the fuel bulb and the engine will run for another 5+ mins. We haven't had the time to do some of the tests yet and will in the a week or so. We will first bypass the low pressure sensor and see if we can get the pump to work.
So my main question - how long should a fuel pump last? it is the one Moyer sells. I think we have had this one working for around 12 years. |

Several things in this post:
1. A fuel pressure gauge will make troubleshooting this way easier. 2. Outboard squeeze bulbs are not even close to safe enough to use in an enclosed space. 3. Fuel pump longevity is not really known. There is no magic number they all die at, they might last 2 days or 20 years. Mine is older than 12 years. It works fine, but I do carry a spare |

I didn't know the danger of the bulb - I will remove it. We have been sailing with one for the last 15 years, but I understand the problem with it! I will order a new fuel pump to have it on hand when we run a few tests next week.
Where does one get a proper fuel pressure gauge for a motor like this? Thank you for you help! |

Is it safe to keep an inline fuel pressure gauge permanently attached to the fuel line like this on on amazon.com. Or should I get a removal tester?

There is more than one person on here with a gauge like that installed. I have an electrical gauge I can read from the cockpit.
Regarding the squeeze bulbs, they come in handy, but I have had more than one of them leak. Sometimes they split open suddenly and squirt me with fuel - - but I have also seen them get subtle cracks that just weep a little bit at a time |

Moyer also sells a low fuel pressure alarm kit.

Thanks Joe, I will look for an electric fuel pressure gauge. I also like that warning system from Moyer. I went ahead and bought a new fuel pump from Moyer.

Is this the kind of electric fuel pressure gauge like you have? https://www.amazon.com/GlowShift-Tin...%2C131&sr=1-25

Actually the fuel pressure gauge issue is pretty simple. Fuel line connected between fuel pump and carb. Gauge is about $20 and and inline adaptor that fits your hose size. is about $12. Mine is a ebay "Marshall" brand 0 t0 15psi - stainless body, glass lens, liquid filled. Works great for many years. shows a steady 2.5psi. This will quickly tell you if you have a pump problem or carb issue[float sticking, running lean etc]. Good luck.

This is it: https://www.ebay.com/itm/26205847825...cAAOSwUBlZsJt0 That store hasn't had 5 PSI transducers for some time, you would have to look around for them. Autometer 15 PSI version: https://www.amazon.com/Auto-Meter-49...ps%2C48&sr=8-2 The Moyer alarm kit isn't a bad idea either, the fuel pressure is not critical as long as it ends up less than 5 and more than 1. Found one! https://www.ebay.com/itm/35386176019...EAAOSwZZdhaBlS If you want to see the gauge in action: http://www.dellabarba.com/sailing/a4/A4.mp4 Sadly they seem to rust a bit on the chrome trim Last edited by joe_db; 01-20-2022 at 10:03 AM. |

Joe, that is a very slick system you have. Mines a "poor man's " version which is non electrical and where you need to glance at the engine to get a reading. Something is better than nothing but I just may upgrade to yours one day.

I solved a couple problems by removing my squeeze bulb and replacing the fuel line. I'm fairly certain the bulb was leaking at one of the hose connections, so the fuel pump would not draw fuel (the system has to be air-tight, or it'll draw air instead of fuel).

OK - we have removed the bulb, replaced the pump with a new one from Moyer, bypassed the big fuel filter & water separator (Rancor S3228TUL) and check most everything else. But, the engine will run in idle with out the choke, but went we throttle up the engine dies - as though it is not getting enough fuel.
We will next try to clean the carburetor this weekend - this is rather frustrating! Any other suggestions as to why the engine dies when throttled up? |

The obvious one is the main jet is clogged

If it turns out to be a clogged main jet it is imperative you determine the source of the clog otherwise you risk it happening again.
