Number 8 is the part! FUEL REGULATOR
You CAN take it off in situ, but it's best not to as dirt getting inside can cause big troubles.
Get a magnet on a stick tool before starting this job in situ.
However, as it looks nice and clean there no reason not to open it up.
Clean around the big hex nut where the fuel inlet pipe fits.
Take off the fuel inlet union and tuck it out of the way.
Loosen the nut thing the fuel pipe was fitted to. Unscrew it carefully ....
IMMEDIATELY watch out for a stout coil spring under that nut! Hold on to all the bits.
Take the nut right out.
Use the magnet to catch the spring and lift it out. LOOK OUT for the lower spring seat. It MAY come out with the spring, or you may need to fish it out with the magnet.
You now need to lift the nylon filter out, and it may be quite stiff. DON'T rip it to bits!
As it comes up it may bring with it the regulator cylinder itself. Anyway, you then use the magnet to fish out all the rest of the bits.
Clean the mesh filter from BOTH SIDES till it is spotless.
Starting from the BOTTOM .....
a very light coil spring ... a small plunger (regulating piston) .... a small stronger spring,..... the regulator cylinder sleeve, ...... the sleeve guide plug thing, ......the filter itself .....the big sleeve retaining spring,..... and the inlet connector nut.
You clean all these bits, and ever so carefully put them all back! This way ......
FIRST put back the very light coil spring. Make sure it sits nicely the right way up, and not on its side.
Now very carefully apply a small dab of clean yellow grease to side of the plunger thing, and slip it into the bottom of the regulator sleeve. Use only enough grease to stop the plunger (regulating piston) dropping out - a TINY bit will do. In some of these the middle sized spring must be inserted from the bottom. Check this in yours.
Now place the middle sized spring into the top end of the sleeve unless its already fitted from the bottom.
Place the sleeve guide plug onto the spring so that its spigot end fits into the end of the middle sized spring and carefully fit the mesh filter on to the sleeve.
The whole caboodle is now assembled ready to fit - only the biggest spring isn't there yet, and it's the second last bit to fit.
Making sure the wee piston plunger won't drop out, just gently drop or lower the mesh filter with the sleeve attached into the hole. Put the last biggest spring inside it, and press it down with your finger to seat the filter.
Replace the inlet connection nut thing, attach the fuel pipe and Bob's yer flip!
Worth a try. It isn't black magic!
But you MUST WORK CLEANLY!
If you drop ANY crap inside you are probably going to have BIG troubles.
