Difference in Fuel rails T34 & T25?
I believe I read this somewhere on the board , but I can't find the thread anymore 
Is there any difference in between these rails, as I want to weld a fuelpressure sensor onto my T25 rail. However I still have a T34 rail lying around with boss welded on already. Just wanted to know if these are interchangeable.

They are different, the cups that the injectors fit in are longer on the small t due to the different inlet manifold design,the mounting lugs on the plenum of a small turbo are a lot thicker thus placing the rail further back, if u fit a big t rail to a small t car then the injectors will barely seal at the inlet manifold side,not good where petrol is concerned.......
