#454719 chrisxv1600al (User) Fresh Boarder Posts: 52 Using a different fuel pump 3 Months, 4 Weeks ago   Hey guys. Juined my fuel pump (it's been a long day...don't ask)in the prosess of relocating it & see the original Yamaha (Mitsubishi) pump is not cheap. Was wondering if anybody has replaced it with a different style of pump, like a universal in line pumps from the parts store. I see in my service manual it says the original pump is between 2.1 & 3 psi. The parts stores have these pumps in a variety of pressures & I can't see why one wouldn't work (probably better than the original POS) just wanted some opinions. I would like to just get rid of it all together, but I just ordered a new needle & seat for it, & I don't want to mess with float levels & this "grizzly valve" to try & go pumpless. Thanks in advance for any info.   Logged     The administrator has disabled public write access. #454725 Mr_Shamrock (User) Platinum Boarder Posts: 2901 Re:Using a different fuel pump 3 Months, 4 Weeks ago   As many who have went pumpless I am sure there will be one floating around here that can be had for next to nothing. I will be going pumpless soon if you don't find one. There is a vaccum pump that has been used and I believe there is a write up in the tech section. P.S. Go pumpless and forgetaboutit!   Logged     Last Edit: 2012/01/28 17:41 By Mr_Shamrock.   The administrator has disabled public write access. #454726 texasscott1 (User) Two of a kind Platinum Boarder Posts: 1824 Re:Using a different fuel pump 3 Months, 4 Weeks ago   The stock pump supplies fuel according to demand which may not be the case with the universal pumps, I don't know. When the carburetor needs more fuel the stock pump just speeds up a little so the running level is kept at a certain point. It uses a complicated mechanism to accomplish this. As far as the reliability of the original pump how does 70,000 miles and 13 years sound. Knock on wood.
