<div dir="ltr">Al,<div><br></div><div>For what it is worth this is how I cleaned out an old Healey gas tank like what you have described.</div><div><br></div><div>Drained the tank and removed and stripped off everything except the fuel pickup which isn't removable but has a mesh screen on the end. Once the tank was dry I flushed with a garden hose then added a vinegar solution and a length of chain and with some assistance shook the tank so the chain would scour the inside surfaces. Flushed with water and back flushed the pickup tube. Hydrochloric (Muriatic) acid is very effective on rusty iron. The problem is neutralizing the acid when done to stop the acid attaching the iron. Water won't do it. Vinegar is easier to handle, neutralize and dispose of. Heat up the vinegar solution for a little added punch if not getting the job done.</div><div><br></div><div>Install a good inline filter preferably between the tank and the fuel pump to catch any residual debris.</div><div><br></div><div>Hope this helps...

<div>I am in the process of reviving a car that has sat for several years. The gas tank was partially full of old gas, which when pumped out brought out a lot of rust. As such, I am thinking I will be needing to clean out and restore the inside of this tank.</div>
