## Customer Reviews

### ⭐⭐⭐⭐⭐ Awesome quality product
*by R***R on June 18, 2025*

Worked just as described

### ⭐⭐⭐⭐⭐ Excellent quality, runs like new!!
*by B***D on January 9, 2025*

My Jeep (OEM Carb replaced with GM TBI off a Chevy 4.3) was hesitating bad under acceleration. Could not get steady fuel pressure. Installed this spring and now getting a rock steady 9psi (I have an adjustable regulator) and Jeep is running like brand new! Spring seems like a nice quality part and holds rock steady pressure under all RPM's.

### ⭐⭐⭐⭐⭐ Check your fuel pressure first!!
*by L***1 on November 1, 2021*

I used this product to fix a 1984 Pontiac Sunbird 2000 with a non-turbo 1.8L 4cyl engine. The beauty of GM TBI is they're all pretty much the same as long as they're the same vintage. My car was having hyperlean problems past 50% throttle (bucking, missing, backfiring through intake). On the freeway, there was a very noticeable intermittent miss. I replaced every single sensor, replaced the fuel pump and filter, rebuilt the throttle body (except that spring), replaced the EGR valve, rebuilt the entire ignition system, and still no improvement. Testing fuel pressure gave me 9 psi - within spec, but on the low end. Replaced my stock spring with this gem, and all of my engine issues have finally disappeared! If you are experiencing intermittent backfiring through the intake under load, definitely CHECK YOUR FUEL PRESSURE before just buying this and throwing it in. People who have been leaving bad reviews for this product very obviously are NOT doing that.
