Just replaced the fuel pump, filter and shut off valve on my converted 914 (six):

It all should fit. The 914 area is similar to a 911. You'll notice the 911 front crossmember.

911 with factory internal filter screen; no shut off valve):

914 with shut off valve and external filter (w/911 suspension shown):

Some thoughts:
Excess fuel hose will allow extra bends to install fuel components as necessary.

A fuel filter (internal or external) is preferred to prevent sediment from entering the fuel pump. Short of removing and dismantling the filter canister or tin-canning an OEM-type filter, there's no convenient way to inspect how much debris is contained in it. A see-through, cleanable filter is one answer to monitor the contents. The object here is to remove particles sizes large enough to clog/damage the fuel pump. Smaller particles can be filtered downstream before entering the intake system.

However, since a filter mounted in this location, there's less opportunity to inspect on a periodic basis. The trunk is a more preferable location for ease of service and maintenance. OTOH, a low-mounted pump can rely more on gravity to provide fuel to the pump inlet.

The ball valve allows filter and/or fuel pump service without draining the tank or pinching off the supply hose that may or may not be pliable after years of service.
