clogged up internal Fuel pump

[Calijackalbob]

Hi Guzzistis.
I'm in the process of Caffienating my Bellagio with a V7 tank etc,....



I bought a plastic V7 tank that was replaced after the chrome cracked up. It has been unused for a year or more. The question I need advice on is this:
I removed the fuel pump and found petrol resdisue, 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.
Bob.

Don't even think about cleaning the filter, fit a new one. That will catch any residue the pump spits out.

Thanks Brian, but the real question is, would the fuel resideu clog up the pump, and if so, how can I unclog it?

If the fuel pump is stuck, it may be freed up using carburetor cleaner. Do not use anything like WD 40 as oil based material may expand the plastic parts and make it worse.
