Try not to get over-excited here, but today’s thrilling installment is not about painting. Nor is it about sandpapering!
Just for a change the weather was slightly on the ‘moist’ side, so I decided to forgo paintbrush and sandpaper and instead seek alternative entertainment in that other never-ending quest; the search for the source of the air bubbles in Herman’s fuel system. After crawling up and down the length of the van, tightening every hoseclip and joint I could find in both fuel lines [delivery and return] I noticed that the length of pipe which leads from the diesel plugs back to the fuel filter looked a bit worn [this return pipe feeds excess fuel from the injectors back into the fuel system]. It’s not a crucial vaccuum-tight part of the fuel system, but I decided to sort it out anyway.
As luck would have it, I found in my stash of ‘things which might come in handy’ a section of plastic tube which was the same diameter as the dodgy one. Unfortunately, it was a bit too short. Undaunted, I had another hoke around in my hoard of
crap useful stuff and found - of all things - the nozzle pipe from a footpump [footpump itself long since departed to the great junkyard in the sky]. The footpump nozzle was the same diameter as the tubing and at the end where it screwed into the pump was a nice wee metal connecter which was just the right size to screw into the old return pipe tubing at one end and push into the new tubing at the other.
So I cut the worn section off the old tubing, spliced on a section of the new tubing with my new found connector and the job was a good ‘un. It also gives me the added advantage that, with the new pipe being transparent, I can now monitor the fuel [and bubbles!] which are feeding back into the system from the injectors - as well as being able to watch the bubbles feeding into the injector pump from the fuel filter.
