My oil pressure gauge is erratic. I believe this is a common fault. Does anyone know where the fault normally is. sender or gauge.Alot of owners fit after market gauges but I would prefer to use existing hole, can a totally different gauge be fitted in the original hole.
Fault is normaly on the sender connection , I\'ve read a couple of fixes but never really tried any of them apart from cleaning the connection
The fixes are I\'ve heard of are -
clean the spade connection on the sender and lead
take out and clean the sender unit ( I read this somewhere )
run a new cable from sender to gauge
Best bet is to go for an aftermarket gauge , there is a how to to fit SPA dual digital gauges in place of the origional gauges , there nice gauges its just a shame they don\'t match the rest of the dash
