Description

Fuel pump diaphragm oil seal – very hard to locate part needed if you see oil coming out the weep hole on the bottom half of your fuel filter!

Please note that a mounting spacer must be used when reinstalling the pump to prevent pump arm overtravel; failure to do so usually results in the fuel pump being destroyed! The diaphragm is removed by separating the lower half of the pump after removing the lower body screws (which gives you access to the seal). Rotate the diaphragm 90 degrees to release it from the arm forks; reinstallation is just the reverse.
