EN-49248 Injector Rail Assembly Remover Tool 6706 for Cadillac, Saturn, Pontiac and Chevrolet 27-214 Direct Injection Engines

Was pulling the injector rail on my 2014 Silverado 4.3 with 2500000 miles on it Tried for hours with pry bars, wood blocks as fulcrums couldn’t get the rear most injector to budge. Ordered this tool and it works like a charm. The bolt that goes into the blocks bend a little under the load however once load was removed it was straight (did not yield) A couple tips for using. 1. I put anti seize compound on all the threads; will prevent binding/galling and make overall operation smoother. 2. Go slowly and evenly. I would tighten tool until they were under a good load then gently use the prybar on both ends of the rail, then tighten again and repeat. The first 3 or four inches come up are very slow. If you just crank down all the way and try to rush it you will probably bend the tool.

I do not have the expertise enough to handle this kind of project. This did not seem like something I needed for a stuck injector.

Arrived with nuts the wrong size (the ones that are supposed to thread onto the hooks and do the actual pulling as you tighten them). The Hooks are threaded for SAE size 1/4x20 and the nuts were 6x1mm. Okay, not a huge deal, got the proper size from Ace Hardware, only to find the metal blocks that the hooks are supposed to go through aren't drilled large enough! Having bought two sets (as the manual states, so you have one tool in each fuel rail mounting hole), ONE out of the 4 tools was drilled large enough. Drilled the holes out to fit the hook and found the metal was INCREDIBLY soft, like butter. On first attempt at use, only finger-tightening the nut down onto the hook, the circlip holding the metal block to the long "anchor" bolt slipped and fell off. This is where all the force of the tool will eventually end up, and it hadn't even experienced any load yet! Luckily, working at a pro shop I was able to get a wide washer with 6mm hole to stack between the top of the long bolt and the tool-head handle l to prevent the block from slipping down. Now, finally, I could make a serious attempt! I had soaked the injectors in PB Blaster for almost 24hrs before this point, and pretty quickly observed the long bolt you thread into the block was bending, like others here have stated, but it straightens back out once tension is released. And like others I used a pry bar with a sliced section of heater hose as a cushion to pry on the fuel rail near each injector slowly, working from front to back progressively, eventually success! You NEED something like this tool, though I do have to wonder if the expensive OEM version would be stronger. Until I read the other reviews on here I was scared it might snap, leaving a broken section inside the cylinder head!

Arrived quickly, and worked great

Worked well

Easy to use, did just what I needed it to do.

Wrong threads. Try to screw the hooks in perfectly straight and they instantly try to start stripping. So I have to pay money to get these sent back to either get a refund or another set. Terrible

The studs that screw into the block are not fully threaded, so I had difficulty getting the hooks around the injector rail. I ended up drilling out the holes where the studs go and using some 100mm long bolts and nuts in place of the studs. Then I was able to pull the rail easily enough.
