fuel pump question

[Scat Pack Fever]

This is a dumb question, but what connection goes to the carburetor? The threaded connector or the slip on connector?

 The threaded end goes to the carb. You can use a section of 5/16" or 3/8" preflared brakeline and bend it to fit the application.

Cool! Thanks! I am guessing I shouldn't use rubber fuel line? I have the connectors that thread into the carb and the feul pump that the fuel line slips on. Or should I use straight brake line and no rubber gas line?

from the factory there is a rubber line approx 8" from the line on the frame to the fuel pump on the engine to allow movement & 2 short pieces of rubber to accomadate the fuel filter on the way up to the carb . The filter should NEVER be installed before the fuel pump

Cool! Thanks!

Sorry if this is kind of a hijack but why is that Neil?

No Biggie! I was wondering the same thing.

The filter should NEVER be installed before the fuel pump

  If filter is installed before the pump when it starts to block/stop dirt it will restrict flow quickly because there is only atmospheric pressure pushing fuel through it, plus the filter itself can cause a restriction as well. Whereas if on pressure side it then has full pump pressure to over come restrictions.

Looks like I gotta move my fuel filter.

Thanks for the info CP, Aussie

Exactly as Aus said , you have a prefilter in the fuel tank & anything that can get through that will nto hurt the fuel pump , you always want the pump to push fuel through the filter , it is far more effective than trying to pull through a filter ! If you like being stranded with fuel starvation problems just put the filter on the suction side instead of the pressure side !!

Another reason you don't want to run all rubber gas line is the possibility of vapor lock.  Back in the day, I broke the metal fuel line my my wife's '67 Cougar with a 390.  I replaced it with rubber gas line and had problems with vapor lock on hot days.  Apparently the rubber gas line doesn't keep the fuel as cool as the metal lines do.  FYI.

 As a  note; those autopart store pumps don't last very long. Especially if the car sits for extended peroids of time. Just replaced one with less then 2000 miles on it. Luckly it happened at home base so toeing wasn't necessary  .
