bottjernat1 2,190 #1 Posted May 26, 2020 Wanted to share what i did for the fuel system and how i redid it! Now to redo the float. I found out yesterday the float is bad. Im pretty sure it has been replaced because the float i found yesterday in the dd12 carb was plastic! It should be brass correct? I also used all new fuel line and it is made in the good old U.S.A! another issue i found out on sunday when i got it running was it drives great but the lift cylinder doesn't want to move it tries but to know success. 1 Share this post Link to post Share on other sites
bottjernat1 2,190 #2 Posted May 26, 2020 Is this the replacement float for my dd12 carberator? The original float part number is 201217 i am pretty sure! Does 1460380 replace that? Share this post Link to post Share on other sites
pacer 3,175 #3 Posted May 26, 2020 I have 2 of those carbs - one has brass and other has plastic (I cant recall which I'm running) The crack in the plastic probably doesnt matter since its solid and cant leak like the brass ones can. That carb can be real picky trying to dial it in. Heres one on the bay for about half Jacks price.... https://www.ebay.com/itm/Carburetor-Float-Marvel-Schebler-fits-BF-BG-B43M-B48M-DD11-DD13-DD15-Onan-F68/291600917395?hash=item43e4c4e393:g:vqYAAOSwr7ZW3RgY:sc:USPSFirstClass!71033!US!-1 1 Share this post Link to post Share on other sites

bottjernat1 2,190 #6 Posted May 27, 2020 OK i took the float out of the dd12 carburetor yesterday it doesn't appear to be solid. And the crack is leaking. Share this post Link to post Share on other sites
pacer 3,175 #7 Posted May 27, 2020 Well, there you are... what one tractor has another will be totally different. My float is a black plastic and though I didnt cut it open, it sure gave me the impression it was solid - like a type of styrofoam. A too heavy float would sure make an already temperamental Onan run bad! All the more reason to grab that brass one .......... 1 Share this post Link to post Share on other sites

pfrederi 18,223 #10 Posted May 28, 2020 You may want to consider moving the fuel filter to the back under the tank so gravity fills it. The fuel pump is going to have to work to pull the fuel up to front uphill and into the filter fill it and then up tot the carb.... 1 Share this post Link to post Share on other sites

I mainly did it so that i can see how clean the fuel is and to see if the pump is doing its job. and easier access to change the fuel filter. Share this post Link to post Share on other sites
turbofn1 5 #12 Posted March 1 Can anyone tell me where the fuel pump is picking up vacuum from? 1975 D160 Automatic with Onan BF/MS 2929e can't seem to find much for images. I like a Chinese blueprint or any pictures of D160 , Thanks Share this post Link to post Share on other sites
