Think i know why my "new" Jeep does not have fuel preasure!

I bought this clean 1995 Rio Grande that has no rot a few weeks back. It had been off the road (based on the inspection sticker) since 2005! I did the computer brain surgery and reclaimed the spark and power to the fuel pump relay, but no pump.

Tonight I pulled the tank and found this! By golly, this just might be the culprit.... I have NEVER seen one this bad before!

Yea, a line flush, new line filter, maybe a gallon of carb cleaner swished around the tank to wash it out... and a used pick up assembly. What I do need is the grommets that hold the top vent plugs on the top of the tank. Anyone know if Jeep still sells them? Or anyone that does?

I bought a '93 Sahara a couple years back that looked the same. It had been sitting for a while with a bad D35, and I ended up replacing the entire fuel sending unit with a used one I found on eBay for $75.

Yea, I am pretty happy with my progress so far. After I replaced the capacitors on the computer and had spark, she fired right up on starting fluid and sounded great. ( For less than a minute anyway...)

Oh boy!

I would replace the whole assembly going into the tank. Rust falling off into the tank won't be good once you get things running.

Bring the tank to a radiator shop and have them hot dip it for a few hours, should clear it right out. Then definitely get new components to put back in, if not clean them up until the shiny metal underneath...

Yea, there is no way that one is going back in! The only way would be if I could tear it down and sandblast it first. But I have a good one lined up, so it should just be a matter of flushing out the tank and lines.

On mine, I just reached in thru the hole with a bunch of rags and wiped the crud out. I kept doing this until the rags came clean. Since its a plastic tank, there isn't any rust to really worry about, just the gunk and junk from the old sender unit and the slime from sitting. Acetone as a solvent will cut most of it. My jeep had sat for 10 yrs before I got it. The fuel pump looked like yours and it still ran for a month before it went. And then I got a new one and flushed and cleaned the whole system.

I flushed the fuel lines by leaving in carb cleaner overnight, blew them out and flushed again until clean fluid came out. For the tank I used a half gallon of denatured alcohol, and a few 3' lengths of chain and swished it around. Dumped the crud out, rinsed with water (no detergent), then repeated. After the second time it was clean. Another alcohol rinse and a few hours in the sun to eliminate any water and it was ready to put back together. I replaced the fuel pump, filter, sender and screen, as well as a carb rebuild to get the whole system up to snuff.
