As mentioned by Aurel - I too used the Walbro, model GCL604 as a direct-fit replacement for my OEM Bosch CIS fuel pump.
Here's a thread discussing CIS pump options and the Walbro
Walbro Fuel Pump ???
I used it for ~ 4 or so years then switched to carbs and swapped to a low PSI Pierburg pump. The Walbro with all fittings is somewhere in my garage, PM me if you are interested in buying it.
If you opt for an aftermarket pump (URO, Walbro or other brand) - I do recommend you find one that retains / uses the original fittings (like the Walbro GCL604 or URO High Output CIS pump with banjo fitting). The OEM rubber fuel lines are metric, and adapting to male barbed fitting with hose clamp is an exercise you would prefer to avoid.
Good luck,
