Does your MAP sensor fit TIGHT in the barrel of the 90 degree bend of pipe?

Thanks in advance :-)

there should be an o ring to seal it, dont take my word for it but i think the petrol and diesels have different size map sensors?

I know there are different size MAP sensors. There are also different size inserts on some of the MAP sensor flanges you can (or could) buy. Ditto about the O ring seal. There should be one, it'll leak otherwise.

Maybe ask Forge about it?
