Great product

### ⭐ Faulty fuel pump
*by B***O on February 9, 2026*

I purchased this fuel pump in November. I have only run a quart of a tank and now will star cold but once pump gets warm I loose all fuel pressure and the truck will die and not restart. This truck is a weekend driver so sits most of the time. Sad that you can not get in contact with the supplier once the window closes. I hope they will reach out to me once they see this review
