Some of the original fuel pumps from the 60s had a much thinner mounting flange. (about half the thickness of the pictured pump) They were prone to cracking around the mounting holes. If your car still has the thin flange type pump, you may need to replace the studs in the block with some longer ones. The 1500 engines and the 1600 engines below R40000 have SAE threads, in this case 5/16 coarse. Later 1600 engines use 8mm x 1.25 thread studs. You can also use bolts, although studs are a better way to go.
The 64-67.5 and some of the early 68 pumps were designed to take a metal output line; and the input and output direction was the reverse of the later pumps. Later cars used rubber fuel line on both the input and output fittings. They made the switch at 1600 engine number R-59199 and 2000 engine number U20-02692. Approximate VINs at change were SPL311-17400 and SRL311-02200. After 40-45 years though, either one could be on your car...

Pump includes 2 gaskets, order a new spacer block if your old one has any problems. ALL pumps need to have the original spacer installed. Sometimes the spacer can be hidden in grime and look to be just an extension of the mounting area on the boss so I would suggest cleaning up the area so you know you are just installing one spacer.

NOTE: The fitting that your metal line screws on to vary. We can usually provide the "correct" one for your car but if it does not match what you have you can swap your old one on to the new pump.
