holley marine fuel pump
Does anyone use the holley marine fuel pumps on their boats,the electric version?i have the red holley pump on my 509ci that i was told by a holley tech that this was the pump to do the job,but i only get 51/2-6 psi at the carb,just with the key on and the bowls filling but i am worried about it leaning out under load and CANNOT aford that.i have called holley back and the tech i got on the phone this time said the pump only supports 400hp which i have 600hp and i need a bigger pump with a regulator???????that way i can feed it a constant 7 psi,what do you think????

Check out aeromotives web site. I just bumped up to 720hp and was running an electric pump at your specs. They were great to deal with and reasonably priced and recommended their marine pro-series part #11110. It was good for something like 1100hp NA and 1300hp Forced. Also make sure your voltage regulator is bumping up to 13.5 to 14volts, mine would not get above 12 and I switched it out as well. Leaning our engine is time bomb waiting to happen, feed the beast. Hope this helps ak.

KYELIMEAGLE,that is what engine i have,a 509ci that made 615hp,what fuel pressure does that pump put in your carb inlet?i think i will swap out the red pump for the blue with a regulator set at 7 psi.
