Review on OTC Tools 6710 Installation Gauge by Anurak Grubb

I did this job at work a few weeks ago. Check the engine gauge chart after a failed condition inspection. Bold rows 1 and 2. Bold like -35 fuel trim on both banks. I came to the conclusion after seeing the oil level so high and smelling of raw gasoline that the pump into the crankcase must be leaking. To the right? LAUGH OUT LOUD. Yes, he came back for a check up a few days ago. No MIL, fuel trim is perfect. No handling problems. The tools work as expected. After removing the intake manifold and fuel pump, a hole is left, like the old distributor hole. Insert the tool into the hole and rotate the engine clockwise until the tool is flush with the fuel pump mounting surface. At first he never sat flush. Eventually I realized it was just the dry landing, it didn't go down like it should. A little lubrication or light pressure from a helper will allow it to come down flush when needed. The service information (instructions) states that the engine must be set to TDC No. 1 of the exhaust stroke. Then wait until the special tool is flush with the GDI/valley plate. But as far as I could tell there were no marks on the crankshaft pulley and I didn't feel like pulling out the spark plug and doing all that. SO. After flipping the motor a few times while watching the tool, I realized I had to apply a little pressure to make it drop (or just lube it up). I realized that it doesn't matter what the actual position of the cylinder is. , you just had to make sure the tool was flush. The second time it's very quick. The service information also states that the fuel feed line must be replaced after removal. I think it was ordered. OEM part, ACDelco. It was the wrong fuel line. It was definitely a high-pressure line with the same threaded connections, but completely irregular. So I didn't swap it. I understand why they are talking about replacing because it's a flared gasket at the end that the gasoline flows through and it's covered with a foam insulator (very flammable). So you're saying to do it for "security reasons" but mainly to avoid a court case. Anyway, I made sure the repair was good before shipping the truck. I also double checked when he came back for an exam a few weeks later. All is well.
