'73 Fuel pump: its cut, where should it go?

[beandip]

If the mechanical pump is acting up , watch it closely . Depinding how it fails , it can pump gas into the crankcase , or it can cause a major oil leak . One the local Z drivers lost the engine because of a faulty mechanical pump. His oil sending unit was acting up also and the loss of oil pressure , he thought was due to that . He almost sezed the engine . He had to replace the engine anyway . Gary

Well that just sucks. This sounds like a very poor design to me. Guess that's one thing that's gonna have to come off now. That new elec fuel pump is sounding better and better all the time.

Yikes! How does a failing mech. fuel pump manage to leak oil?

doesn't leak oil, just blows a diaphram and pushes gas into the crankcase.

Ewww, lovely! Well thanks for the heads-up! :-)

scary. I totally bypassed my mechanical pump, but its still bolted on. Should I remove it?

[BadDog]

I would probably say "yes". And there are nice block-off plates available to cover that spot too :-)
