    Question about paint chips in fuel system

    I wish there was a filter in the high pressure line that could be easily changed. I am worried about the new fuel cells having similar issues, though they might be fine. But I am also worried about additional connections that could leak!

    Question about paint chips in fuel system

    Just wanted to say thanks for all your help. Managed to get the fuel rail off before wrapping the boat up for the winter. The only difficult thing was getting the injectors out - they were the originals and well painted in! I bought my self an early Christmas gift, and tested the injectors as...

    Question about paint chips in fuel system

    Good point - I did limit running once I got fuel pressure under control.

    Question about paint chips in fuel system

    Yes they did. I called Monterey to inquire about access, and they suggested to cut the deck. Fortunately I am only 5' 8" and 160lbs so I can squish into some tight spaces. At age 61 the body does not like it.....

    Question about paint chips in fuel system

    I did perform the compression check - 160 to 165 PSI on all cylinders. I am planning on removing injectors this off season.

    Question about paint chips in fuel system

    Props have been the same for 20+ years, so I don't think that is the culprit. They are pristine and not damaged.

    Question about paint chips in fuel system

    Great link. Left me with a question that might be a misunderstanding. How do the paint chips get past the screen on the high pressure pump? Is it simply too coarse to stop them?

    Question about paint chips in fuel system

    I have a perfectly good Atlas in the basement and never even thought of that. Got hyper-focused on finding a socket that would work!

    Question about paint chips in fuel system

    Thank you I can get the arrestor off, so should be good to go. Good idea on compression check. Changed the plugs yesterday but forgot my compression gauge, but simple enough now that I finally found a decent spark plug socket that fits under my GLM manifolds.

    4.3GXI-E fuel consumption - resolved

    Just wanted to follow up for anyone interested. Plugs looked fine, even after running on the rich side all season. Pics attached. Now thinking injectors might be suspect. Replacing plugs did not help situation.

    Question about paint chips in fuel system

    My boat is a 2004, so I have dealt with this - basically changed fuel regulator (3x) and fuel cell. But wouldn't this also effect the injectors?? I do not know much about my injectors, besides being over 20 years old. The engines are 4.3GXI-E. I do not know if these injectors have screens...

    Fuel Line Sources

    Thank you and sorry I should have specified. I was asking about the engine side hoses (to and from fuel pump).

    Fuel Line Sources

    I want to replace the fuel lines on my 4.3GXI-E's. They are 20 years old, and I do not know how long they truly last. Is Volvo Penta the only source for these lines?

    4.3GXI-E fuel consumption - resolved

    I will not keep you in suspense, it was fuel pressure. Early in this saga, I did check fuel pressure and injector leak down. Everything looked fine (55psi and no measurable leak down). I am either senile, stupid or this somehow snuck by me. Being a rather recent widower, I would rather be...

    Sqeeking sound from belt after impeller inspection

    Spray water on the belt - if it quiets down, it is the belt. Clean pulleys and replace belt. Check tensioner - replace if weak. I am not sure what weak is...... so if replacing belt does not quiet it I would then try replacing tensioner.

    Compression test

    Basically, compression readings should be within 10% of each other on a "healthy" engine. Some folks say within 10 psi. So, you are right there on percentage and just outside the 10psi rule - which is a rule that does not make much sense since it does not take into account actual compression...

    4.3GXI-E Excessive fuel consumption continued....

    2004 Monterey 282 Please judge - I value your opinion. I love and hate this boat. It is not my cup of tea, but fit the bill for all involved. A couple reasons I picked this boat. I do over 100 mile runs (Chesapeake, Delaware, Atlantic) so twins are nice - so far in my 60 years on the...

    4.3GXI-E Excessive fuel consumption continued....

    Thanks - I will research the ability to perform the balance test. I have not poked around with the Techmate too much yet. Fuel pressure test should be easy. I understand the need to be loaded and keeping the conditions same.

    4.3GXI-E Excessive fuel consumption continued....

    I went down last week to do this, and my brand new tool set on the boat has a 5/8" spark plug socket too thick to fit under manifold! Will try again next week with thinner socket.

    4.3GXI-E Excessive fuel consumption continued....

    Looking for some help with my thinking. I was chasing excess fuel consumption even though engine seems to run fine. Might be a squeak bit rougher idling, but starts fine and runs fine. Here is what I have so far: Ended up using a Techmate to pull data from engines. Boat has twins, so easy...
