Going to be installing a AEM boost & Wideband tomorrow and I need a new fitting for my boost gauge sending unit so I am wondering if anyone knows what size the line is? I found a thread for a boost gauge install and I think he said it was 1/4 but that was a LSJ so im not sure if its the same?

 

Since no one seems to know. Yes it was 1/4".

 

Whatever fits on the nipple, u can use 5/16 or 1/8 as in the hole size . If ur not sure always take the smaller size, u can always boil water, stick the end of the hose in the water, and it will slip right on, and cool for a nice tight sealed fit

 

I usually just take a tape measure and measure the hole then goto the store and measure the holes to see what's closest

 

Thanks for the tip I may have to try that one of these days.
