So I pulled the old fuel filter off, you could hardly blow through it, I banged out a whole lot of rust looking particles. Then I pulled the fuel pump out, it doesn’t look new to me but I’m an amateur maybe it is, the fuel sock is totally clogged up with rust particles too and the bottom of the gas tank seems to have some too, is there any way to resolve it? Is it normal to have this much trash/rust in the bottom of the tank? If they did change the fuel pump they definitely did not flush the tank or anything, what can I do to get all this trash out? Maybe some kind of siphon pump to suck it out with some gas.

 

when I revved the engine slightly some of the pressure dropped to about 25psi from what I could tell, I couldn’t tell the RPM I’m just guessing

 

From the info provided, appears to be a fuel pressure problem.

Depending on the system on the vehicle, if it has a Fuel Pump Driver Module , either the pressure sensor is not sending the correct info to the module or the fuel pump is defective. If it has the "Module" , it should be located just above the spare tire mounting on the chassis cross member. If you see it there look for corrosion where it is mounted contacting the chassis cross member. If all that applies, the module will need to be replaced.








it contacts

 

The trash in the gas tank appears to be metal rust pieces, I was able to remove the majority of the trash with a long magnet, I kept getting large amounts, I know I should have dropped and cleaned out the tank but I didn’t really feel like going through that, it took longer time to clean it out this way but I wanted to do it this way, I have several pictures showing the different amounts I got out after awhile, everything was stuck in the plastic baffle area where the fuel pump goes, I looked around in the tank and I didn’t really see any rust, it was just around the fuel pump area really

 

Evidently a lot of water managed to accumulate in the tank and do it's work.
Cleaning the tank as best you could will help. Adding some "dry gas" containing Isopropyl alcohol ,on a regular basis, and routine fuel filter replacement will help move the moisture out.. DO NOT use any additive containing Methanol because that can damage the catalytic converter.

Let us know how you make out, thanks.

 

the previous owner did tell me it sat for years but I didn’t realize it would be this bad, I plan on changing the fuel filter in about 2k miles or so just to see how it is, I would rather change a filter out too early than to mess up a new OEM fuel pump, I also might even pull the new fuel pump and rinse the fuel sock out in a container of gas, since I have an easy access panel for it now, new gas tanks are $300 so.. I’ll try it this way, if it continues to be an issue I don’t mind pulling the gas tank, I’m just trying the easier way first, thanks for the help, I’ll be sure to update as things go on, I’ve gotten the gas tank just about clear of rust particles in the bottom before I installed the new fuel pump, with the new pump and filter the engine sounds smoother, easier “sounding”.

 

Well my shortcut didn’t last as long as I thought it would, after about 300 miles I could really feel the hesitation start back up and struggles under load noticeable, so I pulled the new fuel pump, clogged again, I went ahead and ordered a new gas tank and pulled the old one out, with the gas tank out I was able to see all the rust it’s terrible condition inside the tank I couldn’t see it before I guess. Plus the rust particles where the fuel pump goes was just as bad as before like I never cleaned it out with a magnet. Now the access panel I made inside the van for the fuel pump did make it easier to drop the tank because I could unhook all the fuel pump connections and wire connector before dropping it

 

I installed the new tank, waiting on the fuel pump( getting a new one because the other one was not showing fuel level correctly, returned it under warranty) a flat motorcycle low jack made it an easy install, much easier than a transmission, much lighter too. I went ahead and replaced all of the hoses because I found them in poor shape and one of them was cracked, possibly my occasional evap code?



after all this hoopblah I’d have to say I’ve basically got a new vehicle with an old body at this point
