GET RID OF THESE
AND REPLACE WITH

Are these the ones you were testing for the 500efi?

Thanks for asking. NO they are not. These injectors above in the pics I have been working on as well for a replacement = the 454 and 502 black engines.

I have flow tested so many silver bullet injectors that the volumes just do not come out well for balanced flow volumes -- even brand new out of the box do not have great balance flow volumes. Also the silver bullet injectors suffer at the connector all the time. I had a person recently sent me 8 of his silver bullet injectors and every connector was bad.

The Hp 500 EFI are totally different fuel injectors than these in the pics above. The looks and size plus spray patterns / volumes and so forth are different than these injectors in the pics above. Both injectors that I am selling are plug and play with NO ECM recal needed period.

We have tested for a longtime before I ever opened up my mouth having them. I have 2 boats currently now with hp 500 EFIs ---- one boat has over 50 hours on it that is doing real well. The other boat has only 8 hours on it. I am maintaining and testing these boats about every 2 to 3 weeks. around every 6 to 10 hour timeframes. Just for a jist of all this.

Winter projects I will have 4 more boats using my upgraded HP 500 EFI fuel injectors.

I have them so when anyone is ready. Like I said they are in 2 boats close to me running around. One boat has over 50 hours and the other is almost 8 hours. Close enough to call it 8 hrs. I wanted to get over 100 hrs on the boat using my very current upgraded hp 500 injectors but every week that goes by, I feel alot more confident using them without a doubt. Keep in mind they have / had to be real world tested first and foremost especially being a plug and play with NO RECAL required drop in injector(s).

Also the way I am looking at it - the original injectors caused the failures to begin with and have no idea why someone would rebuild their engine(s) and put those 1986 technology injectors back in. Even with injectors there is a life span at some point. The multecs really have a short life span compared to other injectors in the industry.

I tried sending you a PM, but your inbox is full.

Sorry about that - I need to hire someone to take care of it. Wish it was fan mail haha just messing. I will clear out some THANKS
