Not a power upgrade, but I'm pretty sure that two out of my four heater plugs need replacing, and it is of course the two that are most difficult to get at.
It looks like I have to remove the fuel pump to take them out, but does anyone know whether this is a the case or not?
Cheers,

I'm sure there's lots of info on this site detailing this topic but I know that on my 1.9 it was just over an hour job and lots of fiddling around with small wrenches and a magnet. Pump and injector lines all stayed on; I just put a magnet below the plug I was working on so if I dropped a nut it stuck to magnet. Or stuff some rags down there. Do a search on this site.
the most important tool for this job is lots and lots of patience, and a steady hand helps too, especially for cylinder number 2. it does help to remove the injctor lines, but it's not necessary, and it's a pita either way
Pull the injector lines, pull the two plugs that are relatively easy, loosen the buss bar on the other two ( but leave it attached). Unscrew the other two plugs and use the buss bar to take them out as a pair. Replacement is the reverse. Only way I've found short of pulling the pump.
Thank you gents, some excellent suggestions. I shall have a crack at it this weekend with the help of some ratchet spanners....

I just did this not too long ago when I replaced the cylinder head on my TD. I should have done it while the head was on the bench, but somehow, I overlooked it.
For me, the hardest part was getting the tiny nut on the end of the glow plug to hold on the bus bar. I ended up putting a piece of a plastic bag on the closed end of a 8mm (?) wrench and then pushing then nut into it. It essentially holds the nut on the wrench until you can fish it in there behind the pump and get it started. Same thing might work with an 8mm 1/4 inch drive socket turned by hand...
I'm not saying it's easy...it does take patience. The magnet idea is a good one... I should have thought about that before I dropped those little washers behind the pump.
