Don't know if anyone might be able to advise me but I'm having an issue with my boost gauge.

It was working fine this morning, I did an oil and filter swap and went to fill up with petrol and noticed the boost gauge wasn't giving the out the right readings if at all.

It still pulled ok when I put my foot down, mpg may of seemed a little low but could be due to the weather. The gauge in question takes a reading from the vacuum pipe which converts it into an electrical signal and I can't find any splits in the pipe. What's the likelihood of it being an electrical issue?

Normally it'd peak at 21 and settle around 18 when planting it but now it'll probably reach 10, most of the time it's in the negative part. I'm a bit stumped
