I need to clean out my fuel system. How should I do this? I feel like I need to do the most extensive job possible, but would prefer not to drop the tank out. I would do that if I need to, but may need directions. Also, how hard/expensive is it to change all of the fuel lines? Or could I just clean them somehow as well? I have put seafoam in the tank, but I feel like I may need to do a little more.
Sorry for the stupid questions...

 

Drain the tank, remove the fuel pump assembly and then scrub the inside with degreaser and a stiff brush. If you start getting rust, then stop and take the tank to a tank shop who can coat it internally.

Replacing the fuel lines is fairly straightforward but access to them can be restricted. From the dealer I wouldn't expect them to be monumentally expensive. If the lines are in good shape then you can fill them with solvent and blow them out with compressed air.

 

Thank you, sir! This is going to sound dumb, but I have to ask, will I be able to reach the whole surface area of the tank through the hole where the fuel pump goes?

Again, thank you! Your website is very helpful as well. I'm diggin' the eccentric shaft lamp too!!!

 

im probably gonna clean my fuel tank when i get my new engine, just to clean it. is there any reason why your doing it?

 

My car was sitting for a long time whenever I bought it years ago, and then I had to park it for 4 years.
I remember changing the fuel filter years ago and the gas that came out was brownish. I meant to do this way back then, but never got the time.

 

Id check the inside of the tank visually, if it looks good just loosen the fuel fiter, and run the fuel pump till the tank is empty, then fit a new filter. Post count huntin'

 

That sounds good. I can't recall exactly why, because it's been almost 4 years, but I'm pretty sure that I had a reason to be certain on needing to clean out the whole fuel system. Hell, it couldn't hurt anyways.

 

Hehe nah and if you dont then itll haunt you for years to come A friend of mine did this because the last owner had added to much oil to the fuel so instead of giving the apex seals some sweet lubrication it clogged the plugs.
