Fuel pressure

[Diablo54]

Was out at the lake today and while out in the lake the boat died. I looked back at the fuel pressure meeter and it said zero. I chilled for a while thinking how the hell I was going to get back to my truck and then tried to start it and the pressure was up again for a short time then died. It did this off and on the whole way back to my truck. Does anyone know what the hell is going on. Do I need a new fuel pump????

Sounds like the fuel filter is sucking something up and its clogging then when it sets this junk falls back down and it restarts.

Mechanical or electric pump? Maybe dirt in the fuel filter? Enough fuel in the tanks? Usually no fuel preasure means no fuel. Sounds to me like its starven for fuel. Hope it helps.

Try performing a fuel-pressure output test, to see if your pump pases.

WAS IT GETTIN HOT THEN SHUTTING OFF? IF SO, YOU NEED TO CHANGE IT, THEN INSTALLED A BYPASS TYPE OF FUEL PRESSURE REGULATOR, IT'LL KEEP THE PUMP RUNNIN COOLER AND WILL EXTEND THE LIFE OF THE PUMP TOO.

I do think it was running hot cause it would just shut off, then i would wait around and then it would start and have no problems for a while then off again?

Is It A Holley Pump?blue Or Red?

[Diablo54]

The pump is blue

[IMPATIENT 1]

Diablo, I Had The Same Trouble With The Holley Blue's.i Still Run Em But I Bought A Bypass Regulator For It, Its Never Happened Again.i Would Replaced The Pump And Buy A Bypass Regulator If It Were Mine.you Can Sell The Pretty Chrome Regulator The Pump Comes With On Ebay For 15 Bucks.or Keep It For A Later Project(no2).

Check Tanks Vents Too!!make Sure There's No Problem Gettin Fresh Air Into The Tank.the Pump Will Overheat For This Reason Too.

Ok looks like I will put the Bypass regulator for it also. I can not make it out of town before the weekend and want to take the boat out. Does anyone know where I can buy the new pump and bypass regulator?

glad to help! you can still run a holley blue with this regulator, or even try runnin your old one with the new bypass regulator and see if it fixes the prob..then install a new pump if needed.check those tanks vents too, damn mud dobbers clogged mine up last summer, done some wierd shit too.

[Diablo54]

I did not order a new pump since it is almost brand new so I will try the new regulator out this weekend and see if that works before I order a new fuel pump cause the one I have in the boat has barley been used at all. :)

CHECK YOUR GROUNDS WHILE YOUR THERE, FAULTY GROUND CAN CAUSE A HEAT RELATED INTERMITTENT CONDITION TOO.

Well the part is still not in but I do have a question? I do have a return line that I put in before this problem. Will this have any affect when I put in the regulator in????

IF IT HAD A RETURN LINE FROM THE REGULATOR BACK TO THE TANK, IT ALREADY HAD A BYPASS REGULATOR ON IT.THE HOLLEY REG. YOU ORDERED WILL HAVE INSTUCTIONS FOR THE RETURN SYSTEM, I TAPPED MINE INTO THE FUEL VENT HOSE SINCE IT WAS EASIER TO FIND A ADAPTER FOR.

[Diablo54]

Finally got all my stuff in on Sat. Going to insatall it tonight after I get some time to chill from the BBQ I went to today and had too many beers to install all the new parts hopefully next week the fuel pressure will not dropp to 0 and leave me chillen in the middel of the lake. Thanks for all your help IMPATIENT 1 I will let you know how it all goes next week hopefully I will be happy and not have to ride the Jet skies all day :cool:
