We have another update for you A new Mercruiser fuel pump could improve the issue slightly, but did not fully resolve it. Recently rebuilt carb has a defective accelerator pump. Fuel is not being delivered as much as it should. Taking into account the fact that the old pump built up too much pressure and spilled into the venturi, it seemed that using carbs made sense In the end, I think that an aftermarket carb would have been fine. The latest update The boat I had on the lake did not perform. As soon as the secondary's opened, it almost stalled because it was bogging down with a full-throttle hole start. The problem smoothed out after the plane landed, but the engine couldn't supply enough fuel for takeoff. Might be okay with a smaller engine and a smaller carburetor. To make sure I get a good pump, I will have to use OEM. Today was the day I installed it. My review will be edited if it leads to trouble. The boat has a 1991 Mercruiser 4-cylinder engine. The 3LX is a 205hp vehicle with a 4bbl Quadrajet carburetor. Original pump developed too much pressure at more than 10 psi (pegged gauge) when the starter was also engaged. The carbs flood, and the engine has a bad idle and bad hot starting. I am confused as to how a spring diaphragm pump can fail as a result of leaking fuel all over the top of the engine. It makes seven gallons per minute with a new pump. A maximum of five psi is desired. The Qjet is a very sensitive device and has a 5 dB sensitivity. A maximum of five psi is desired. There is a Q/A that states this carb offers 5 to 8 scfm and I prefer 5 scfm. The boat ran like a charm today on a muff. On the right is a photo of an old carburetor taken apart. There were traces of rust and corrosion, but the.
As a result, the pump initially failed to function due to a The housing was from the old pump, so I took the housing off and put it back A lack of fuel flow allowed the boat to lose speed, and it had to return to port. My boat has a fuel pressure gauge on it, and it decreases rapidly as soon as we Due to the fact that it was disassembled and fixed once, it cannot be returned. I basically wasted $110 with nothing to show for it. There is not one happy camper in this group.
When I was blowing a whistle to fisherman on the shore, the pump went out. In getting passed by kayakers on the way back to the ramps, I had to do the paddle of shame. Although the pump is not designed to be easily changed, it can be changed in about 1 beer. The preinstalled fuel filter and gasket make it easier for this process.
The cheap route of purchasing this one instead of the OEM one and having to spend $160 on it proved to be unsuccessful due to the pump not being able to keep up with the carburetor. If you want the OEM one, pay the extra money, but other than that I was happy with how quickly it came, how nicely it was packaged, and how three gaskets were included.
Replaced the mechanical fuel pumps on a boat, it works fine. I watched YouTube videos on how to replace a mechanical fuel pump. For this to work, you have to keep the rod thingy pushed over. It is very difficult to remove grease with very light grease. You can find 5/16-inch vinyl hose at Home Depot in the plumbing department, not at the auto parts store, to replace the clear line if needed. So, as a conclusion, it is no fun to work.
I had my mechanic install the unit without any issues. I paid $75 for this. Over $250 was the price for the 00 Mariner. I'd like to receive $10. 00 It is hard to believe.
I need a new fuel pump for my 1990 4 cylinder. I found this 3 Mercruiser to be an exact fit and it arrived sooner than expected. Our research found that other vendors charged more for shipping and took longer to ship. Based on my one experience working with this vendor, I think it's worth your consideration. plan to make use of their services in the future.
It fits and functions perfectly! The item arrived as described, fitted directly to my 1989 Mercruiser 4 and has never let me down. This pump has the same number of shafts as My experience with the new pump has been good thus far. I have only used it for an hour or so,.
