Thank you Gentlemen, and thank you Hugh, I'll talk with the seller and see if it will take 20% HCl and if so, order a Milton Roy pump.
Steve, good suggestion, I am currently looking for an ultrasonic cleaner that will accept a 911 case half. But I'm not even sure an ultrasonic cleaner would work. I think most lines are rusted on the inside. And the acid I use is pretty weak stuff. When it's used up I just dump a box of baking soda in the bath and it's fine to go down the drain according to the EPA.
Fan, MFI lines are from the mechanical fuel injection systems for 69-73 E's and S's, RS's and was used last on the SCRS.
I actually use the acid for what you describe, removing plating. Parts are then surface prepped and plated. Here are some lines in the process.
What's nice about the HCl is it dissolves rust very effectively so it should be the best solution for making sure the lines are 100%. The issue is if one line isn't completely free, that cylinder will run lean which could cause catastrophic failure.
