🛠️ Efficient Oil Pump Primer Tool for GM Chevy V6 V8 Small Big Block Engines Review

The reason I'm giving it to the stars is because it didn't work right out of the box. I had to disassemble it and spend a lot of time fitting it into the oil pump groove on a Chevy 350.

If you are building a GM small block engine, this tool is a must. Before starting the engine, this tool, together with the drill motor, fills the entire oil system.

Overall I think the fit and finish was wrong. But if you're trying to replace a camshaft or topping up an engine on a shoestring budget, this tool isn't so bad…

Well I knocked out the roll pin and thinned the metric blade to a thickness comparable to a Chevy countershaft. Now it fits small block or big block Chevy engines! Misleading and erroneous claims by these companies have become the norm. What are the options? Send back to China? I made a filler tube, but I settled on one that directs the oil into the main gallery with extra volume. An aluminum bushing mimicking the distributor shaft can route the oil the same way as the distributor does, but who
