Fuel pump disassembly and cleaning

Evening all, after looking for a cleaning fuel pump tutorial and not finding one...I took my pump apart anyways. The description is going to be brief as I'm doing this after a 12 hour shift of driving a semi truck and I'mdoing this from my cell.

I started noticing a loss of power in the upper rpm band and as the weeks went by it started getting worse. I have a full exhaust so I know it couldn't be a collapsed cat and I topped off the tank so I know it wasn't due to a low fuel level. Only thing left was the fuel filter.

After endless searches, there is no filter listed. There's "no way" to disassemble the pump. Basically ur 2 choices are buy a new pump assembly for God knows how much or roll the dice on a used one from ebay.

I am frugal (poor) and save up for the things I like or build if possible. I love doing my own maintenance

After pulling and draining the fuel tank, I carefully removed the fuel pump assembly held by 6 socket cap screws, I believe 4mm?

Then I took a bunch of baby harbor freight screw drivers and slowly began prying off the lower half, I did crack one tab but honestly not worried

Carefully pryed the mesh filter and o rings (4) and tossed the base and filter into an ultrasonic bath for 20 min

Then I rinsed and hit the mesh filter with a steamer from a distance and the base until I saw no more sediment. Yes I also blew steam thru the "tubes" in the base plate.

I'm going to reassemble Saturday but I don't see a reason I can't hit redline anymore. I'll add to this if I run into anymore problems

If anyone can find a better replacement filter, please comment. I don't know many times I'll be able to clean that mesh filter. It wasn't exactly designed for that

outstanding contribution to the site man!! Many thanks! Please do keep us posted, and share any other pics notes if your able

Eventually I'll figure out how to update the main post

Reassembly was straight forward. Took the bike out for a hot lap.

I can hit redline again but only in first and second. Now I'm not super fluffy but I also don't have an Italian body. That being said my gsxr 1000 had no problem getting me to 200.

The fuel pump may have sucked in some if the aluminum powder

I will be pulling it apart and replacing the pump

Update, pump is fine.

Did more "testing" on ride from work.

bike 'chokes' at WOT, however if I roll the throttle and stop about 10 degrees b4 WOT, I can hit redline in 3rd, 4th, and 5th

Ran outta runway to verify 6th but it seems to reason that there's a calibration issue with the drive by wire system

Taking my noble steed to the local Ducati Doctor to get that calibrated
