There was a change in fuel pump design JUST for this reason. All 1981 cars came with a fuel pump with at built in check valve. To my knoledge this is not serviceable. However, as of the '82 models and later, a newer fuel pump was used which had an external check valve. Many of the 81s now have the newer style put in them, but ones still with an original pump most likely will not. If your pump is the newer style, (which can be determined by a "dome" nut on top of the banjo fitting for the fuel line, as apposed to a flat one) you should be able to get a new from from a DeLorean or bosch supplier. (Dont know for sure though, since they come with the fuel pump, and I haven't seen them listed separately. I can't imagine they wouldn't be availible though.) If you have the old style pump, you probably should just get a new from from a DeLorean supplier, and check the condition of the inside of your tank while your at it. Good Luck.
