What made you choose this particular product?
I put a Holley drop-in fuel pump hanger into a fuel cell without baffling. This pre filter soaks up fuel, reducing fuel starvation.
Is this your first time buying from this brand? Did you consider other brands?
Love Holley products.
Was it easy to install? Any installation tips that will help others?
If you can change a fuel pump pre-filter, you can install this.

What made you choose this particular product?
I am running a 200cc and can't afford a v8 but still want to be one of the cool kids
What were you trying to accomplish by adding this product?
more horsepower
Was it easy install? Any installation tips that will help others?
Not an easy install since you need an adapter that I ended up milling

What made you choose this particular product?
I had a Holley carb on the truck and wanted to stick with the brand since it was still working great. I just wanted to have the peace of mind that comes with EFI.
What were you trying to accomplish by adding this product?
Better MPG and Horsepower.
Was it easy install? Any installation tips that will help others?
It was easy to install. I took the truck to an exhaust shop to weld in the O2 bung but did everything else myself. The wiring and fuel return line were a lot easier than I was expecting.
Once you’ve had a chance to use the product, did it meet your expectations?
It exceeded my expectations.
Any additional comments?
I highly recommend this product to anyone wanting to keep a traditional look but have the benefits of EFI.
