Hi,

(Sorry for my poor english, i speak french mainly)

I own a firebird 67 400 with a Carter mechanical pump. With todays gas evaporating a lot easier after 2-3 days not running, i have to crank the engine a lot before starting. Have you ever heard about using a SD 73-74 mechanical fuel pump to solve this problem ?

Is there a better solution ? I want to stay with the mechanical pump because it's quieter.

Thanks a lot

Pierre

Doubt it would solve anything, both are good pumps.

Ce diluant à peinture qu'ils nous vendent et appellent «essence» va s'évaporer peu importe la pompe utilisée

Une petite pompe mécanique, installée près du réservoir d'essence, qui ne restreint pas le débit de carburant lorsqu'il est éteint serait la solution. Vous pouvez l'activer momentanément chaque fois que vous souhaitez démarrer la voiture après s'être assis, puis l'éteindre si la voiture a démarré. Peut-être quelque chose comme M. Gasket # 12S ou le Holley Mighty Mite.

J'aime la pompe Holley moi-même. Bonne chance!

That paint thinner they sell us and call 'gasoline' is going to evaporate off no matter what pump you use.

A small mechanicel pump, installed near the gas tank, that doesn't restrict fuel flow when off would be the answer. You can turn it on momentarily each time you want to start the car after sitting, then turn if back off when the car started. Maybe something like the Mr. Gasket #12S or the Holley Mighty Mite.

Here are a couple links:

I like the Holley pump myself. Good luck!
