Fuel pump mods

While doing the core plugs I also replaced the uprights, stub axles and trunnions. Having checked why I could not set the front wheel bearings properly I found that the stub axles were worn, so that was stripped down where I found the trunnions were also knackered, with pitting on the top of the threads of the uprights. So it's all new now, so it 'should' be a lot safer and better now.




The problem I was chasing next was fuel related, for some reason the Facet primer pump was running dry. It was suggested that the old CAV type fuel filter does not like having petrol forced into it, so along with a repositioned high pressure fuel pump I fitted a filter from a Volvo 240, though I needed to get some more fittings for that.
The re-positioned pump was achieved by using a Lucas fuel pump cradle, but unfortunately I soon found it was not what I needed as the pump cooling ring could not be used in conjunction with the cradle.




I set about measuring up the cradle, adding on dimensions as required to suit, which soon resulted in a template and then a sheet to bend up.




After bending to shape and a few holes cut for the pump body and fixings it was ready to be put together, it has since had a quick coat of paint to protect it.

New pipes

Following the results from the rolling road and after a brief sojourn to the secret workshop, the GT6 came back home with new under car exhaust pipes. The outlet of the 3-1 collector has been made to a larger diameter for a short length before splitting into two pipes for most of the exhaust run and then joining up again to go into the silencer.







Unfortunately I couldn't go out and test it straight away as we noticed another core plug has started leaking and I didn't have any spares to hand. I soon knocked out all four core plugs along the side of the block and as there was a bit of black residue left in the bottom of the block. I flushed the system through and once again after refitting the plugs to make sure I had water flushing through the whole system. Still not quite sure what has caused the core plugs to fail.
The plastic bags are there to try and reduce the amount of water getting poured into the starter motor and exhaust pipes as they were going to be too much of a pain to remove from the car.
