Re: Fuel Pump Check Valve.

["Jim Reeve" <ultra@xxxx>]

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.
