    Problem Solved

    Well today I went down and got my 3rd Holley Blue pump..they replaced it without any problems..also went ahead and bought all new fuel lines from my tanks to the filter, and filter to the pump. Put in the new pump and lines and it wouldn't pump at all..So I started blowing on all the fuel lines to see if they were clogged or something...I could hear the slightest air leak coming from the gasket on the fuel filter. Put in another new gasket..problem solved...but I haven't taken the boat out yet to make sure..vacuum leak could have been the whole problem..Wednesday we will see...I did pull the tanks a couple of years ago and had them steamed.

    Hey titty (love saying that), did you actually pull the tanks out to check them or you just looked in them to make sure no water. I would seriously look into a venting problem. Most of these tanks have built in vents in the caps (which I do not trust). I made larger vents for my set up. Pop the caps open next time this is happening to you. Also make sure your fuel pickups in the tank did not fall off inisde the tank and are not clogged. Also make sure the ball check anti siphon thingy is not messed up in the factory fitting elbow at the tank.

    again WTF.

    you guys keep saying mechanical this and that,but what about the others that run electric pump and they have ni problems
    Tech guy said the only other thing it could be is too many amps..not volt related..I don't see how I could have too many amps..same setup for 10 years..unless the new pumps are more sensitive to too many amps and gets hot..??

    i've ran dozens of holley electric pumps of the yrs and have never had 1 fail. those west coast guys see alot more ambient heat than we do trav, they might just be overheating them.

    You'll find far fewer people complaining about their mechanical pumps than those with electrical. I've never had a mechanical pump fail on anything (not just boats) and I'd be willing to be there are darned few failures it we were to poll.

    Honestly.........unless running an electric pump is a necessity, I'd vote mechanical all the way.

    4 year old holley blue.deadheaded the pump ran great for years.

    replaced it with a jegs brand,new regulator also.ran for 10 minutes,screwed up.lost pressure was hot as a mutha f-cker.then started leaking.

    replaced that pump with a new holley blue just like i had.this sob is doing the same.

    does ,run it for 10 minutes or so gets so hot you cant touch,then the pressure falls off.let it cool down does fine till it gets hot agian.

    i have replaced fuel lines, made sure things are clear,no change WTF.

    What to do with the old one? Go to Avi and throw it across the parking lot.
    That sounds like a man with some fuel pump chucking experience.

    Bypass regulator set up on tunnel ram, 660s. Out the bottom of the regular back to the inlet side of the pump.

    I would'nt run more than 7 -7.5 psi. You could change out the regulator and see if it is the problem.
