My machine shop says my injectors are clogded up due to rust in the fuel tank, I did run my fueltank allmost compleetly empty trying to get it started after my rebuild. They say replacing the fuel filter should solve my problems with the clogded up injectors. But what should I do with the fuel tank. Keep it this way or replace/fix it? (I don't even want to know what a new fueltank costs)

PS should I place an additional filter between the fuel tank and fuel pump, the original filter is placed after the fuel pump. Rust/dirt particles going directly trough the pump can't be good for it I think.

I thought the fuel tank was plastic? Can the internal components rust?

how can rust go past the fuel filter?

I checked it and you are correct, the fuel tank is plastic, the man at the machineshop who is cleaning my injectors said red stuff was coming out of the injectors when he cleaned them. So what could this be, just debris or is some part in the fuel system rusting? I did run the fuel tank almost completely dry.

By the way, I heard some terrible stories about engine fires caused by fuel leaks. I just rebuilded my engine and I don't want to see my baby go up in flames. Any suggestions what would be wise to check/replace?

It is the metal lines going to the engine. And the rust can be fine enough to go through a fuel filter.

Most fires on this board were caused by old rubber fuels lines that attach to the fuel rail. At least one of these was supposed to have been upgraded after a recall. There's lots of infoirmation in the archives, just do a search on FIRE.

Well, that search might be a little broad. Here's one on leaky hoses:

The leaky hose is a DOT recall which the dealer will replace free of labor and parts cost. I have bought at least 10 944/951 with engine fires from there at the insurance auctions at one time or another. In fact, I have a burnt 87 951 right now I am using for parts. Make sure you replace that line or it will cause a fire since it runs from the fuel rail to the damper and its right above the spark plug wires, which many people do not replace due to the cost. These wires arc and spark right against the fuel rail (awesome design eh?) and next thing you know, poof. The early year tanks are metal (pre 85.5) and the late ones are plastic. If anyone needs a tank I will give you one if you are near by and come to pick up.
