recommissioning a clogged up fuel pump
« on: November 01, 2015, 11:51:27 AM »
Hi Guys.
In the process of caffienating my Bellagio, I bought a plastic V7 tank that was replaced after the chrome cracked up. It has been unused for a year or more. I need advice on is this:
I removed the fuel pump and found petrol residue, a thick brown goo, the colour and consistency of honey inside the tank. My concern is that it may have clogged up the internal fuel pump and filter and made them unusable. It's a major issue because, I need to be certain the fuel pump will work properly when the tanks are switched, that it won't clog the injectors, ...... and, because I am cutting up wiring, from the Bellagio pump to make it fit the V7 pump, I want to be sure everything is working right before I switch tanks - pumps, cut wires and commit to the new V7 tank.

Is there a way of
1. Testing the fuel pump and filter before installing them on the bike.
2. Cleaning the fuel pump and filter without damaging them,
3. Should I soak them in solvents, petrol, ethanol, thinners, detergents......... .

I would love to be able to fix any problems before I switch tanks/fuel pumps, cut wiring, etc,.... want to do the switch and be riding it the same day.
Any advice appreciated.

I would submerge it in a pail of fuel, rig up a discharge hose and put 12 volts to it. Run it until it's pushing clear fuel out, test the pressure if you can. I personally like to run a little Marvel in my fuel when I think of it, I believe it does help lubricate the pump.

Take the fuel pump.  Look at both ends minus the hoses.  Spray carb cleaner in one end.  Prop the fuel pump up so the cleaner stays in.  Take a probe and see if you can turn the impellor blade.  Don't force it.  See if you can turn it.  Put a new filter on.

Thanks for the advice guys.  http://wildguzzi.com/forum/Smileys/default/bow.gif
Have you actually tried these solutions?
The running 12 volts through it while in a bucket of fuel is scary. Visions of a big bang, me and the bucket burning....

Anyone have a tried and tested solution, want to throw in your 2 cents?
