Easiest way to empty out stale fuel

Recommended Posts

My car has been off the road for 4 years with 1/4 tank of fuel in and it fired up just fine to begin with but I haven't finished working on the body work so its only done a few short in and out of the work shop starts, its running shit now as it obviously doesn't like these 1 minute trips and needs a run but I also want to get the fuel out as its most probably stale and not helping. What is the easiste way to get it out? I read use a paperclip across b+ and fp in the diagnostic port in the engine bay but which pipe do I pull? the one going to the fuel filter?

Take the spare wheel out, and the tank cover plate off, pull off the return from the fuel rail to the tank unit and extend it to a container. Do the paperclip bridge. No wrestling with the over tightened flare on a stock filter., or trying to direct fuel from the outlet side of the filter. Personally i wouldn't bother, just use the fuel on a bit of a run out. Then add some fresh. I have run cars on 20 year old fuel. i wouldn't go ragging it though until it's used up.
