Fuel Pump Plumbing Question
I've relaced the fuel line and fuel pump on my '85 GS project, and I'm trying to decide the best way to connect the pipe that runs from the pump to the carb. Is it ok to connect the pipe directly to the pump, or do I need to use a hose between the pipe and the pump in order to let things move a little? If I use a hose, it will be fairly short and I'm having trouble getting everything situated such that the hose wouldn't have to make much of a turn.
Thanks,
Rich

well i would recommend the hose ... but this all depends on how you go on about attaching the metal line to the pump ... it will need to be something that can be taken off later just incase the pump or line go bad ... and not to mention the obvious one, fuel leakage.

I used a Comp pump (back when I had a carburetor), and I have the following to say on them:
1) Good pump -- quiet and reliable.
2) It must be installed with the motor up, which you have done.
3) It can be installed upright without cutting through the floorpan if you mount it along the inboard frame rail, just aft of where you have it now.
4) Resist the temptation to overtighten the two screws at the bottom of the pump that hold the gerotor cover on. If you overtighten them, the pump will either be too noisy or will seize. If this does happen, you only have to loosen the screws a little and the problem is solved.
5) If you're running Weber carburetors, there's an LP or "low pressure" version that will make a pressure regulator unnecessary.
