The Reliable and Efficient Standard Motor Products FJ503 Fuel Injector Review

Standard Engine Parts (SMP) is a powerful name for parts and mechanics. I was hoping this injector wouldn't be a cheap fake. It wasn't like that. I got a serious increase in fuel economy and takeoff was instant. The idle was erased and there was no more flooding as the old injector was an original design and had many miles on it. It didn't work so I bought this version with a new design. Don't worry about buying a so-called upgrade mount as it is NOT REQUIRED at all. Use the original bracket…

Works on my 2003 Chevy Blazer 4.3, but note that this doesn't seem to apply to later models that came with an MPFI spider, but earlier models that came with a spider CPFI and poppet valve . valves. Fitting the top of the injector body through the intake manifold plenum was very tight on my '03, but it fits without damaging anything. Once inside they really work - I've driven the truck about 20,000 freeway miles since installing it. The easiest way to get the old injectors out is to remove the…

Has worked well so far, better mileage, better response. A fuel pressure regulator is also defective. This installation took a whole day for this technology. You need to carefully bend the injector hoses to fit and there is a special alignment chart where you cross 1 and 3. You have to lubricate the compressor seal or you won't get through. I was also able to use the old braces instead of buying new ones. First check the tightness of the gas pipe by turning the key for a few seconds. Schedule a

I said it was easy to install. I think it depends on your skill level. Mine was in a Chevy Astro van and I still wouldn't say it's difficult, but I'm still working on everything I have. Yes thought it would be with the new bracket no but it still fit my original just the weird bit was trying to fold its legs to fit the injector bracket on 3 and 5 for fear of breaking it but it works if you take your time and read the instructions and/or watch videos on you tube replace the injector outlet seal…

Installs with the original bracket - as mentioned, don't waste your money on an accessory bracket. Worked right away. No more turning the key, listening to the running fuel pump, repeating, repeating and hoping it starts. I can no longer hear the pump running, it keeps the pressure. It's scary bending the tubes until you realize they aren't pinched. Just try to guide it like the original spider and don't bend it. Follow the instructions to connect the injectors to the distributor holes. The two

Excellent product. Perfect spare part! My only complaint was when the part arrived, the instructions said I needed an updated replacement bracket. I'm still driving the car, I didn't want to get in without all the necessary parts. I couldn't find it on Revain, but I did find it on the Summit website and placed a rush order. It's been 2 days and I still haven't received my part. The Summit order was over 3 weeks late. I read in a review that the original bracket worked fine on a Chevy 4.3 so I…
