89 formula 350 gas tank question
Hi folks
Been a while since I have worked only car. Getting ready to reinstall my gas tank. I took it out some time ago to install a new pump. There are four feed lines coming out of the sending unit. One is gas feed one is return and one is I believe for pressure. However I have a fourth line that had a plastic part that since broke, and was lost. My only guess is this was some sort of pressure relief valve but I can't find anything that states what it was and used for. Any ideas to what this was and where to get a replacement would be great. Thanks!

Thanks for the quick reply. I have gone to 2 auto part stores, no luck. I have check the factory service manual which I have, the drawings show only 3 lines coming out of the sending unit. I am attaching 2 pics of what I am talking about. The pic shows the line having a white plastic piece coming out of it. What was on it broke off upon removal and I cannot find the part which I thought I preserved.
From the bottom up:
1. line with threaded nut is the main fuel line
2. 2nd line up from fuel line is the return I believe
3. 3rd line is for the pressure/vapor if correct
4. the top line with plastic piece is the mistory
