    • Works well on mercruiser 3.0L
Got it in, and swapped the hose barb and compression fitting to the new one. I put a little bit of gas into the pump to prime it. Placed one of the 4 gaskets before and after the spacer, bolted it on. re-attached fuel lines and fired up the boat and it worked great. Engine had a slight noticeably higher RPM. Wondering if my old pump was putting out a bit less PSI than it was supposed to! Never checked the PSI because it did run fine. So far, this one is performing well. ... show more

    • Works so far so good.
Seems to work fine on my 2006 volvo penta 3.0 glp-d. However, I didn't use the gaskets that came with it. I ordered the OEM thicker gasket from Volvo.

    • That it actually works!
Because it's been incredibly difficult to get mechanics to work on boats (very busy), I put this new product in myself. This was an easy install. Went out for a test on the river... after 40 minutes, same problem as before the install. Thinking that the stalling problem may be caused by something else in the fuel supply system, I ended up spending another $550 in parts including a rebuild of my carburetor, new fuel lines and total tune up... but still had the same problem. When I googled this product I found that many folks had issues with new fuel pumps not working so I took one last ditch effort at this and purchased another one of these for $20 more hoping that a more expensive had a better chance of working... Lo and behold, it did! So this product was faulty from the start. Problem is that it took me 6 more weeks of replacing everything else so i missed my 30 window to return this. Kindda sucks how much this part actually ended up costing me! ... show more
