Fuel pump lift height
jps - 15/6/13 at 07:55 PM

I'm just thinking about where to route the fuel lines for my Haynes Roadster. I guess the key consideration is how high the pinto fuel pump can lift the fuel?

do people usually run their fuel lines in the bottom of the transmission tunnel to avoid any issues with flow?

how does a return fuel line work though? as it goes back to the top of the tank rather than the bottom ( you can see I have no experience of the pressure at which fuel lines operate?!)

If you are meaning the standard Pinto mechanical pump fitted to Weber carb equiped engines it will have no problem just make sure the tank is properly vented to prevent vacuum building up in the tank

yep, the standard mechanical pump. I iwas wondering if it'd cause problems If I had the fuel line running up oand over the diff and along the top of the transmission tunnel, .or if it was essential for me to run it along the floor the whole length of the car...

Run it where you like, it'll be fine. The only height that matters is the difference between the pick-up a nd the carbs and thats basically the same as in the Sierra; In between it can be a roller coaster if you like.
