## Customer Reviews

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Good pump, would recommend
  

*by D***D on Reviewed in the United States on May 17, 2018*

So far so good.  This high pressure fuel pump was a exact match as far as I could tell.  I'm writing this after using the boat multiple times and it is still running strong.  I think the one I replace was gummed up after sitting all winter with ethanol gas in it.  I started using the ethanol free gas to help this from happening again.  There are some blogs and thread write-ups about how to loosen up a gummed fuel pump.  The price was good on this, the dealer wanted $300.  I put mine in a 2003 Tige 21i, with the 350 V8.  I also had to replace the low pressure pump as well.  The only reason I gave it 4 stars is I haven't used it enough to say you'll have years of problem free boating.

    Excellent price
  

*by E***Y on Reviewed in the United States on September 6, 2018*

Plug and play. Works as described. We are now having issues with it. We can only part throttle, otherwise it leans out and backfires through the throttle body. I have changed everything around it, and no luck. I'm not getting the 40+ psi needed for tbi

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars

*by D***S on Reviewed in the United States on August 21, 2019*
