I accidentally threw away the oil pressure sender when I removed the engine. Wish I hadn’t done that as finding a genuine replacement would turn out to be impossible. Rumor had it that the oil pressure sender on the S1 Lotus Esprit was out of a Fiat X19 (same because both cars used Veglia gauges), so I picked one up on eBay. It wasn’t the same, so in order to mate the stainless steel oil pipe to the sender, I needed to organize a Frankenstein array of fitting adapters to connect that pipe to the actual sending unit. The adapters needed were a M14 1.5 Female to 6AN Male to a 6AN to 6AN Female Union to a 6AN Male to 1/8 BSP Male. With that everything fit, although I’m still yet to figure out if the sender will even work!
