FJ504 Spider Fuel Injector wi/ 8 Cylinder Compatible with Chevy Pickup V8 5.0L 5.7L 1996-2000 25340347 17114163 FJ10566

Absolute trash, plastic housing cracked after two weeks, engine would not run. Had to redo the entire job because of these horrible parts that aren't even strong enough to hold 60 PSI fuel pressure. You can see here countless complaints about the same issue. Return window closed after a week because they know these parts are junk. Try parts geek instead. Extremely disappointed having the do the entire job twice.

It fit seamlessly and improved engine performance significantly. The installation was straightforward, and the quality seems top-notch. I’m very pleased with the results and would definitely recommend it for a reliable replacement.

While installing the new injector assembly the plastic broke in three places. The tabs that hold it in place broke, one of these studs broke for the fuel lines and part of the plastic housing broke as well. Still usable but frustrating. The factory gasket would not work at all, it's an O-ring and very oversized! I suggest ordering a felpro o-ring kit for $17 to go with this product. The plastic seems brittle so be careful installing

FJ504 spider injection is junk. Deliver December 5th and broke down due to faulty equipment by the 18th. Flooding out cylinder 5 and barely ran to get it home. Dangerous product.

Only worked two days very bad productI had to pay 2 times the work to the mechanic.I do not Recommend

i bought this spider injectors on january 20th of 2023 ,last week my truck began to misfire so i checked iot over, found no problem with tune up but did find injectors were intermittently misfiring so a few days went by and i went to start my truck and it stared but i smelt raw fuel, i open my hood and gas was squirting as fare as on my fender ,i shut it off before it caught fire , and bought another spider system from a [parts store ,installed it and runs great, i want to return this spider system i bought from amazon ,so i am seeing if i can get my money back.i did not think to get pictures to show you ,i just had to get my truck running again.

Had to actually shim the height in order to get it to fit right.Once it was properly installed, seems to work fine.

Converted to MPFI on my 1997 GMC 1500 with 5.7. Starting issue is solved and runs great.

I am sure I speak for most when I say, " we buy from Amazon and their suppliers because of $$ saved".I received this part for my 99 suburban on Dec. 18th. I know I installed correctly as I followed the instructions and seaked out more info. After diaganosing my trucks misfire, and eliminating all other factors, the new part I purchased worked for a month. I am writing this review because if you are considering on doing this job yourself, yo understand that it is pretty much a full day of work.raw fuel in cylinder #5!!!DON'T WASTE YOUR TIME AND OR MONEY. BUY QUALITY PARTS FROM YOUR DEALER OR REPUTABLE MANUFACTURER. BELIEVE ME YOU DON'T WANT TO DO THIS JOB TWICE.DNACC
