1. An apparatus for mounting a device to a pipe, the pipe having a curved wall having an outer surface and a hole through the pipe wall at a position in the pipe wall, the apparatus comprising:
- (a) a gasket conformable to the outer surface of the pipe wall adjacent the pipe wall hole, and having a gasket hole complementary to the pipe wall hole, (b) a mounting block, having at least a part of one surface conformed to the outer surface of the pipe wall adjacent the pipe wall hole, having integral therewith on that at least a part of the one surface a projection shaped to engage the pipe wall hole such that the mounting block can be placed on the pipe over the gasket with the projection engaging the pipe wall hole, and having an aperture extending through the mounting block and projection, the end of the aperture furthest from the projection being adapted to receive the device, such that, when the device is received onto the mounting block and the mounting block is placed on the pipe over the gasket with the projection engaging the hole in the pipe wall, there is a continuous open passage between the interior of the pipe and the device; and
(c) a fastener for securing the mounting block onto the pipe over the gasket such that the projection engages the pipe wall hole.

19. An apparatus for mounting an injector or sensor of an emissions control system to a pipe of the exhaust system of an internal combustion engine, the pipe having a curved wall having an outer surfaces and a hole through the pipe wall at a position in the pipe wall, the apparatus comprising:
-
(a) a gasket conformable to the outer surface of the pipe wall adjacent the pipe wall hole, and having a gasket hole complementary to the pipe wall hole, (b) a mounting block comprising;
(b1) a plate having upper and lower faces, at least a central portion of which is conformed to the outer surface of the pipe wall with the lower face facing the pipe wall, and (b2) a tube sealingly secured to the plate, extending perpendicular to the plane of the plate below the lower face of the plate and above the upper face of the plate, the extension below the lower face of the plate engaging the pipe wall hole, and the end of the tube in the extension above the upper face of the plate being adapted to receive the device, such that, when the device is received onto the mounting block and the mounting block is placed on the pipe over the gasket with the projection engaging the hole in the pipe wall, there is a continuous open passage between the interior of the pipe and the device; and
(c) a fastener for securing the mounting block onto the pipe over the gasket such that the extension below the lower surface of the plate engages the pipe wall hole.
