**Update on Cleaning a low pressure fuel pump*****

[cmitchell2]

It works!!!!! Thanks to many responses and advice from MITCH the pump sings again. I sprayed carburetor cleaner in both ends and let it soak for 1 hour. I put the pump in the freezer for 1 hour. Then filled each end with wd-40 and let sit for 10 minutes. I hooked up some leads from a 12v jumper pack and touched the plug ends. Nothing happened so as Mitch said I gave the pump a love tap and I tried again. She spit out that wd-40 like it was bad whiskey!!! She sings like she is brand new!! I am going to run diesel through the pump to clean her out even more then I'm going to put her back on the boat. I hope that will be the end of this subject. Thanks again to all!

HI pressure

[mitch]

no it was the low pressure pump but you can also do it to the hi pressure pump as well . not letting stale fuel gum up the workings is the key i guess with good filtration .

good work
you should also service your vst while you have the manifold off and clean the filter on the high pressure pump
