Edelbrock Electric Fuel Pump For IS3000Z

[NeonDion]

Hi all,
I’m tired of trying to fix my old Ferris IS3000Z which is not getting fuel from the OEM gravity fed pump. I was recommended the Edelbrock 17301 electric pump. As an fyi I have blown out lines in tank, changed filter etc. etc. and even put a new replacement OEM GFed pump and no gas to carb.
Here is a link to the pump on Edelbrock website with specs. https://www.edelbrock.com/universal-micro-electric-fuel-pump-38-gph-144-lph-gasoline-e85-17301.html
Thanks

I'm having trouble finding the fuel pump used,
was it one like this?

Don't understand the term "gravity fed fuel pump". Most Ferris mowers have top draw tanks so needs a fuel pump. Is the existing fuel pump electric or vacum operated?

Sorry, yes it’s has a vacuum operated pump. Guessing the vacuum is not powerful enough anymore and do not want to tear apart whole engine to see why, it does have air pushing out of vacuum hose but guessing not enough to push diaphragm. Runs great when it was working and only has 587 hrs. On it for a 2004.

Yes current one is similar to example. Popped new one on to check and no gas output.

Could you please give us the make, model, and serial number for the engine?

That’s the one I tried with no luck. Gas getting to pump, not to carb. Installed new tank line. So guessing a pressure problem. So do you recommend the electric pump I suggested to solve? Any side issues using the Edelbrock pump?

Watch this. This gives you a idea how the pulse fuel pumps work.
That vacuum hose is a key to getting the fuel to the carburetor. Follow the video and check out the pump. You could still have a bad pump. The vacuum hose needs to be in good shape and connected at both ends.I would do my best to make it work before mounting an electric fuel pump.
