Hi all - It has been a long while. I'll cut to the chase, the car was stored in a rush for two years and I need to drain the fuel (among many other things). The fuel stinks and is likely in some horrible chemical state.

I've seen some posts here that state there is no chance to siphon through the filler tube... confirmed unless it is possible with a tiny diameter hose which I did not try.

Also, via the fuel feed or return lines... and then engaging the ignition to prime the fuel pump many times over and catch the fuel in a canister.

I am not certain which option is better, I'd imagine the feed line would be best to tap into. Where exactly is this feed line I should tap into? Somewhere under the intake manifold, or directly around the fuel rail / regulator? Is there any risk of burning out the fuel pump by doing this repeatedly?

A photo diagram would help me greatly, or perhaps another method I am not aware of.


Thanks for reading!

 

You won't burn out the fuel pump. Its not doing any more work than driving through a full tank.

BUT! Fuel in the tank keeps the pump cool and prevents burning it up. So don't pump out that last half gallon or so.

I suppose you could pour in a gallon of new fuel, mix it up (bounce the car?) then pump that back down to half gallon. Dilute the bad fuel with good.

 

Whichever method you choose you're definitely going to want to run a bottle of high quality fuel system cleaner at the end before taking her out for a proper drive.

 

Injector cleaner you mean? Any suggestions?

 

Yes and no. Yes it is injector cleaner but I said fuel system cleaner because that's usually the more expensive, larger bottle version punted as a full "fuel system cleaner" as opposed to just the injectors. Liqui Moly is what I used last time. See if you can get that. "Normal" injector cleaner should do the trick as well but it might not have as many additives as the fuel system cleaner. Depends on what you can find.

 

Thanks RolanThunder. I will look around for that.

But still, any help on where the fuel feed line location is so I can tap a hose onto to get this fuel drained?

 

The feed line has a banjo fitting that is attached on the middle of the fuel rail under the pulsation damper.
You will need to replace the two washer if you remove it.
Part numbers 16705-PD1-003 and 90428-PD6-003

 

Thanks so much flanders! I imagine that clear piece pops off/screws off and the rest is underneath? Thanks for the part numbers... adding to the list of parts I need to get from Honda.

 

It's like a big nut under the plastic cover so you need a big wrench to remove it, I'm guessing a 22mm or something close to that.
This is what it looks like from the underside.

 

Thanks again flanders! Going to get those washers and give this a shot soon. I will keep this thread posted.
