removing input pipe on mechanical pump

PostPost by: checkrail » Tue Jun 04, 2024 8:34 am

Hi, When I loosen the pipe connection from the tank to the pump on a +2 the fuel runs out, any ideas as to what to put in the end of the pipe to seal it as I want to remove the engine.

Thanks for any help John

Hi John,
I just push a piece of long hose, maybe old garden hose might do, over the top of the fuel pipe. It doesn't need to be that tight a fit. I then tape it up high up the bulkhead to windscreen height with gaffer tape. You just need to make the end of the pipe higher than the fuel level in the tank whilst you have the engine out.

Small taper pin down the pipe is perfect

On a Plus 2 it is wise to install a fuel cutoff valve at the tank as the line to the egine is lower than the tank and any problem can lead to a leak you cant easily stop. (been their done that)

I had the same problem when I went to pickup my Plus2. When rolling it down the driveway. to the trailer sans engine, fuel started pouring out of the disconnected line. Since I would be installing a 2L Zetec, an electric fuel pump was necessary. I wound installing an electric solenoid cut off valve in the trunk/boot prior to the new fuel pump. The valve operates with the activity of the pump, so the valve is always closed when the ignition is in the off position. At the same time I installed an inertia switch before both the valve and the pump. Same sort as is used in some Ford grocery getters, picked up at one of the local Pick-a-Parts.
