1983 Scrambler "STUMP JUMPER". Frame off, 5.3 Conversion.

Good news is that when I woke up this morning the water had gone down 5 inches. Bad news is the last time I had water it was the level it is now and it took almost 7 days for the water to be gone. Just like a mean girlfriend, they stick around long enough to piss you off.
 
Oh crap Dennis that does look grim!, our area copped for it boxing day last year and its the mess that water leaves behind when it goes that's the real pain in the behind!
If it makes you feel any better though my request for your usual sunshine to come to me has not happened in any way shape or form!.
 
Ironically, even though all this water is so near the Mississippi River none of this drains into the river because of the levee system. All this water will eventually drain into Lake Pontchartrain then into the Gulf of Mexico. Believe it or not the Mississippi does not help drain Louisiana.

I'll get back to talking Jeeps real soon.
 
I'm safe for now, my water has broke. LOL It's down about 12 inches since it highest point. I'm saved only because of divine elevation.
 
I removed my fuel tank today to replace my fuel pump since the 5.3L requires at least 58 lbs pressure and I was only getting 52. While the tank was out I decided to add a truss to my rear axle assembly. This should really help. Now I need to fab a traction bar set up.

How did you diagnose that the pump was the problem and not something else?

1st the chassis Dyno. Then I only had about 50 lbs of pressure at the fuel rail and when I disconnected the vacuum line it dropped about 10 lbs which I think is normal. At full throttle the engine just quit pulling at around 5,000 RPM's. My pump is a Delphin FE0114 and I'll check it for dead head pressure in the morning. But I think I'll just upgrade since I already have it out. Errik you know I want your opinion.

I was hoping that you were going to say that part. You could have a split connector hose in the tank, loose clamps, pinched fuel line, debris in the fuel line, restricted fuel filter, leaking/non-sealing/poorly adjusted regulator diaphragm, etc.... While the tank is out, make sure that the connector hose is the convoluted EFI stuff or fuel submersible EFI rubber hose(like Gates 27093). If you don't use one of the two, the fuel vapor eats the hose alive into a mush and you'll be doing this over again. And also while the tank is out, do you have enough tank venting for a full return system? How many roll-over valves do you have on the tank? Does the return line go all the way down to the bottom of the tank or just dump in just inside the sender?

That's pretty much how I checked it. Dead head pressure was about 65 and the pump is rated around 40-45 GPH. So with a return line open I believe my low pressure gauge readings were correct. I ordered a Walbro 355 LPH pump that should be here in the morning. I think this will work if not it's a start. It wouldn't be my first setback. LOL
 
With the new pump the dead head pressure is around 110 lbs pressure so I know I have enough pump now. I now believe I'm getting about all this engine has to give me. Well you know me, 300 Hp is not enough. LOL I'm looking at a cam and new heads soon and another 75 to 100 Horses. Cha-ching.
 
All the cool guys are doin turbos!! I bet sunshine can even sketch up a nice compact setup worth another 175HP!! :evil:
