Fuel sender unit
Kevin Rowton has been experiencing problems with the sender unit in his TC. He writes as follows:
“My sender unit on the petrol tank failed due to fuel leaking in to the float. I got another and the same problem has arisen again with the dash light staying on when there is plenty of fuel in the tank. The plastic floats simply aren’t up to the job. I think eventually brass soldered floats would give the same problem as modern fuels attack the solder joints. I have had to replace the brass floats in the carbs because of this issue. Has anyone found a solution to this problem please?”
Your editor comments that “I have not heard of this problem with the floats on sender units, so I’m not sure if it is a common occurrence. I have a new (old stock) sender unit for sale, has surface rust, but should be OK. At 20 GBP plus postage it represents a significant saving on a new shiny one (with plastic float?).”
XPAG Oil Pump Circlip Replacement
Visitors to the website may not have seen Graeme Hogg’s comment at the bottom of Eric Worpe’s article. It reads as follows:
“Just to share my experience whilst recently rebuilding my XPAG. My replacement shaft measured 12.96mm OD and the groove 11.09mm ID x 1.31mm width. I have used a spring steel snap ring, SW12-M2400 from Simply Bearings. I replicated Eric’s test using MS test pieces I machined and easily achieved 4Tons (the “bang” came just under 5T). For that purpose, my dummy “gear” was a slip fit on the shaft, not the interference fit of the actual parts. I took care to only expand the ring just enough to ease it into the groove and avoid over stretching. Hope this may be of interest….”
