I am pretty sure I have another fuel issue. I have been out twice with my 97 sport GT40 after the fuel injector issue. to recap It was loading up at idle so I have replaced the high and low fuel pump, all 8 fuel injectors, the fuel pressure regulator the plugs, wires, dist cap and rotor. drained the old gas and refilled it with fresh gas. now I run it for about an hour of wakeboarding and it cuts out at higher speeds. drop back down to idle and it will run fine. I put the fuel pressure gauge on it today and we boarded until it started acting up and saw the fuel pressure drop to 10-15 psi let it idle and the pressure comes back up to normal and it idles fine. take off and in about a minute is starts cutting out again and looses pressure. here is what I think is going on. could be some debris in the fuel tank plugging up the fuel screen in the tank could be the low pressure pump I just put on is bad. could be a plugged fuel filter in the fuel cell. any ideas on how to clean out the inside of the fuel tank?? any other help would be greatly appreciated. |

Check and clean your anti syphon valve located on the tank outlet. It’s where the hose connects to the tank. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

I’m betting your anti siphon valve is stuck or sticking. Mine was a mess but I was able to clean it and it worked after solvent soaking overnight. |

It must be time to update this and say that your anti siphon valve was the issue and say "Thanks Gary"

Ken Here's your answer, I guess he didn't like Gary's advice so he had to get the same advice else where.  https://www.planetnautique.com/vb5/forum/nautique-topics/maintenance-technical-discussion/587386-97-sport-nautique-looses-power-after-an-hour-of-use" rel="nofollow - https://www.planetnautique.com/vb5/forum/nautique-topics/maintenance-technical-discussion/587386-97-sport-nautique-looses-power-after-an-hour-of-use

That's why I wrote what I wrote after seeing his post on PN yesterday You post in 2 places, you'd think you could do 2 updates especially since he originally said it was the anti siphon valve in the PN post before his edit. The edit was a picture of the screen. I guess he figured out what was the valve and what was the screen. |

Problem solved. Dirty screen in anti siphon valve at fuel line by the gas tank. |

| Wow! we have a touchy group here. My notifications from this forum were going to my spam folder while I was getting the PN notifications. I pulled the anti siphon valve and it was fine, that is when I pulled the fuel pickup tube out of the tank and found the crud in the screen at the bottom of the pickup tube in my pictures.I will try to be more prompt in my responses in the future. |

I'd just call it a group who actually thinks about the next guy that might have the same issue and a little closure on the thread helps with that. By the way, how's your fuel gauge? It seems like your throttle body gasket question thread wasn't updated till somebody asked for an update also. |

I suggest taking a look at your settings so your computer doesn't think CCfan is just spam!!  ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |
