Ok so we can eliminate everything from the pump forward, I think it's time for process of elimination.....

Check your lines/tanks and if all is good, get a brass "T" and bypass your tank selector and run of both tanks as one.....

Check the fittings on the fuel/water seperator make sure its not sucking air.....

Im just thinking out loud here, its what i would do :sly:

Good advice as well, and why you should use a gas can then keep moving backward with what hose you disconnect and stick in the can.

The vapor locking is a good one to try. And I would in hopes it's not what I think it is. (You have no idea how much I want to be wrong on this).

I'm still convinced you have a deeper issue, yeah the tanks and pickups/tubes, the hardest thing to deal with of any scenario I know, and just what you DON'T want to hear. But you've checked and replaced all the hoses (Which are the same size I'm running on a dual 750 Tunnel Ram and Terry admitted running on a Blown twin Dominator V-drive, more than enough!), you've tried two different pumps, 1 mech, and 1 electric with basically the same result, so.

Bring the thing to Big River friday, and I'll ride with ya and when it dies, we'll open the fuel fills and see if that cures it. If not, well I'm right. If it does, FANTASTIC, easy fix, vents are plugged or add bigger vents, easier than pulling the tanks!

(I was told I had a vapor lock issue in the Blue Meaney. Don't think that was quite it,  given the result, More later on my theory on that ordeal, but I think it's related to your troubles, lol).

I forgot to mention that I did check the vents on both tanks. Both flow very freely, no restrictions.


The thing I think some of you are overlooking is that the electric pump had good pressure. Until it quit working it was putting out 11psi. That would lead me to believe there is no restricion or maybe it was the hose I removed that went from the fuel water seperator to the fuel pump. IDK...

I would just start trying to elimate what the problem is by taking it all out of the equation.

Go as direct from the tank to the carb as possible and run it under load checking the pressure. Once it runs good that way, add another piece to the puzzle, continuing the process. Eventually you will find the faulty piece.

We can sit here and guess what it could be all day long but there are just to many variables.

If you need a hand on the lake let me know!

No I'm picking up what your laying down however...you have had the same incident with 2 pumps one electric one manual...you said it yourself the pump you sent to clay smith came back flowing something like 21psi...automatically that would tell me something is a stir...honestly ask yourself if your missing something...the only thing I can think of is your sucking air from somewhere...I don't care if the lines installed are two years old I would replace all for a start its cheap insurance...#2 let's just say all that boucing around could have knocked some tubes loose on the pickup...I really don't think its the fuel pump however I have been wrong b4...looks like the problem just isn't going to solve itself...go get a 15 dollar autozone pump and try it....

I think I'm just gonna reinstall the mechanical pump and start checking and replacing all the fuel lines again. I'd rather have low fuel pressure than none at all. :thumbup:

When the tanks get emptied after another trip or two on the water I'll probably pull them and check the pickups.

Probably gonna run steel braided lines too. ;D -8 sound big enough?

Good idea, go back to step one..

Braided lines are pricey and probably not neccesary. I used them only cause you can see everything on mine..... and there purdy ;D

-8 is fine ;)

I might as well dress it up a little bit if I'm gonna go through all the work again. ;D


I'll have the pump and the lines in by the weekend and hopefully be able to take a run out to the lake and test it out. I'll let you guys know how it goes.

Thanks again!

Haha! Will do.

The mechanical pump might have low pressure but it hasn't left me stranded. Yet...

Did you check to see if the fuel water seperator is clogged or restricting at all? Go to walmart and spend the seven bucks and change the filter , when I checked mine all kinds of sand came out of it.
