If you were able to pump 5 seconds of fuel through the main pump, there's a good possibility it continued up into the fuel injectors, and even through to the return line.

If the fuel was as nasty as you say, you may want to consider replacing or at least blowing out your supply and return lines after you've unhooked them. If they are at all junky on the outside, replace the entire length. You don't necessarily have to pull the old ones down, as they are probably undercoated in. Just find a good place to zip tie the new ones in, and put a small piece of bicycle inner tube around it to prevent excessive wear.

If you decide to replace them, talk to your parts person, and see if they can recommend a shop to do the custom furling for the ends. It may cost you $5, but they may also see it as a good public relations move.

Also, make sure you either remove or use a hose clamping tool to block off the rubber return line coming off the top of the tank. Otherwise, it can suction out and make a huge mess.

While you have the main fuel pump mount down, check the condition of the rubber bushings. If they are worn, replace them. They help keep the noise down in the interior of the car A LOT! FCP Groton has them (pn 1346175).

Unfortunately I speak from experience. After I replaced both my pumps on my '86, I ended up with a blocked return line, and payed way to much to have the shop replace it after they couldn't blow it out.

Best of luck!
