15 slows down at WOT

[buck]

My '92 15 hp mercury slows down at WOT. The bulb is soft then, and engine speeds up when its squeezed. I can't see any problems with the hose and I checked the screen in the tank. Does anyone have any ideas?

Hi Buck,<br />Check to see that the fuel filter is screwed on tight and that the o-ring seal is in place. Check the gas connector o-ring. If both are ok then put in a new fuel pump diaphram kit.<br />...have fun...corm

Thanks Corm!<br />Excuse my ignorance, but when end of the hose has the o-ring? Or do both ends?<br />I,m aware of the filter seal, since I lost one once.

Hi buck,<br />The connecter that goes onto the motor does.<br />Also if your hose disconects from the tank<br />their is one on that connector. If the hose screws in make sure it is snug so no air is drawn in past the threads. The o-rings look less like a o-ring, but are a o-ring type seal. Look for cuts or tears in the rubber.<br />Hope this helps, if not post back or email me.<br />...have fun...corm
