Ok well my fuel pump died a couple weeks back immediately after a short bout of spirited driving. I never thought anything of it since everything on my ****** 7 seems to be broken. So i bought a walbro and installed it, during the install I noticed rust on the inside of my tank but didnt do anything about it. So i drive all day that day and the next just fine. The next evening I was coming down a friends block and forgot to dodge the worlds ugliest pothole/bump and the whole rear of the car got violently shocked.

I barely made it down the next block before I started backfiring and sputtering like wild and the car slowly died, never to start again. I go to the rear, the pump is humming but not whirring like it did originally. I disconnect the 2 hoses running from the pump ( cause i didnt know which was which ) and there is no fuel being pumped at all. JUST LIKE MY ORIGINAL PROBLEM!!!!!!

Is it at all possible that there is a large ammount of sediment at the bottom of my tank that got kicked up, sucked in, and burned out these fuel pumps? Of course I have a filter on the new pump (the old one dissintigrated), but maybe its just clogging the filter/strainer so bad it cant recieve any fuel. Any ideas would help, im gonna pull the pump tomorrow and possibly clean the tank if i see a rust filled strainer. Hopefully the pump still works

 

check your fuel filter(not the sock on the pump) we had a similar problem and after almost destroying the pump it completely owned the filter..

 

You need to remove the tank and have it "boiled out" by a radiator shop.

Another option is to remove the tank, add a length of chain (2 ft or so) and add some phosphoric acid (OSPHO is the brand name). Wear proper chemical safety gear!. Slosh the tank around. The scraping action of the chain will remove the loose rust and scale, and the chemical action will convert the remaining rust. I would then coat the tank with any of the commercially available tank coatings..

I would follow this up by removing the main in line filter and back blowing the gasline clean.

VE CAREFUL! You are dealing with flammable and dangerous chemicals

 

I use gear oil to clean dirt or rust out my tanks and always have a filter before the low pressure pump.

what is the best/easiest mothod of cleaning out the tank? I would prefer not to remove it.

 

Please explain to me WHY in the world if you saw that you had rust in your tank would you continue to drive it like that? Do you not care about the car? Seriously? The moment i saw a problem like that the car would be sitting waiting to be fixed.


Do it right bro.. Drop the tank. Replace it. Or do what the others suggested. I would reccomend getting it boiled out.

 

Dropping the tank isn't hard to do. I had my Walbro ruined from all the crap I had in my gas tank.

 

What you "prefer" to do is irrelevant. Just do it right or get rid of the car.
