Standard Motor Products 1704 TBI Kit

standard always makes a good quality product. all the parts i needed were in the kit to rebuild my TBI and get the truck running like new again and noticed a smoother idle. even comes with long screws to make installing the fuel pressure diaphragm very easy. functions as intended with no fuel leaks.

This TBI rebuild kit worked out great for me on a 1990 GMC Pickup with the 6 cylinder 4.3 liter. These kits fit several different engines, which is why there will be a few extra gaskets that you will not need. When installing the large orings around the fuel injectors, I would recommend applying a small amount of lubricant so the orings do not blow out in the future. This kit came with the plastic fuel line gaskets/seals, IAC gasket, and everything else usually needed. The only thing rebuild kits do not come with is the pressure regulator spring. But the spring rarely goes bad. If your spring is not broken then it is reusable. Amazon has the best price on this rebuild kit, I just wasted my time looking else wear. YouTube has a great video on how to rebuild the TBI entitled Chevy TBI Rebuild. Also, if you're trying to troubleshoot a problem with the TBI there is another helpful video called Chevy Running Rich TBI Problem Solving. These videos combined make rebuilding the TBI and getting the truck running an easy process.

Good price everything in the box. Get a gallon of Chem tool carb cleaner. Take tbi apart and soak tbi in overnight and struck agaskets. Come off easy. No snapping. .

This is a complete, comparable TBI kit for the GM model years from around 1986 through 1995. This is only the second time in 32 years that I will be taking the throttle body apart on my 1991 Silverado 5.7L. I experimented a couple of years ago running a half tank of the E85 gas with a half tank of regular gas for aa few months. It works but there's an obvious loss of power when you hit the gas. This kit will help me reveal if there was any unusual corrosion from the E85 fuel inside the small fuel pressure regulator reservoir.

That it wasn't complete and I have to put truck together. I was so wrong if you carefully see in picture you can nearly see the gasket. I usually have to wear glasses to see. Maybe I need new ones. Good gasket kit

Perfect fit. Easy install. No issues. I rebuilt my tbi months ago. So far no issues on my daily driver.

Installed on my firebird with a TBI 305. All parts were there and fit perfectly. There are a few parts that are meant for different years or styles of the TBI so you may not use all of them. To clear up a few complaints I read about the small figure-8 gasket... there are 2 different sizes. One of them WILL fit but the other one wont. Make sure you're using the correct one.

very nice kit for the money thank you
