Found 1987 305 / 350 - Oil Pump & Fuel Pressure Sensor Block Fitting

[85-K5Blazer]

I have a 1987 R10 with a 305 TBI ... and as always ... "It" happens

Looking for the GM 10068580 Oil Pump & Fuel Pressure Sensor block fitting .. 1/8 NPT Male by 1/4" NPT Female 90 Degree brass fitting. The sensor was stubborn and too much wrench pull snapped the brass male portion into the block ..

Fitting was used in both the 305 and 350 SBC with TBI in 87-88 (305) and 87-91 (350)

Fitting is located at the top of the Block just under the intake Manifold on drivers side slightly off dead center.

At first I thought this was a block with a nipple and tried to unscrew what I thought was the nipple I could replace .. it appears it is all a single piece of brass machined to these dimensions.

Would like to find an original due to the design and space . I went to a large M&D Supply and went through all of the brass fitting to make something but everything appeared that it would take up too much space between the engine block and fire wall.

Overall length is 2" with the Block 5/8" wide.

Thanks in advance ! All Help is Appreciated .
