Fuel Pump Question
Last year I bought a partially restored '69 F250 Camper Special. Most of it is stock, but they made a few performance modifications like a Holley carb and a Performer intake. It seems they also changed the fuel system from stock, too.
This morning the truck wouldn't start and from my debugging so far it doesn't seem to be getting enough fuel to the carb.
I knew the truck had an electric "booster" pump installed under the cab by the tank selector valve, but until today I didn't know that this was the only pump -- there's no mechanical pump -- just a block-off plate. This little pump doesn't seem like it'd have enough capacity.
So, my question is how were these delivered from the factory? I assume a traditional mechanical pump was used but I don't know if an auxiliary booster pump is also need or how it was plumbed.
Here's a picture of the existing pump and how it's hooked up: http://www.flickr.com/photos/msisk/3839774235/sizes/l/
I'd welcome any recommendations of how I should fix this, too.
Thanks!

Mike, I am not sure what that is in the photo, but it doesn't look like a fuel pump to me.
Follow the fuel lines to the carb, you should find the pump further up line.
Most older Ford engines have the fuel pump near the oil filter.

Aw yes those our great little pumps I'm using the same setup but as a back up with a switch and a line pressure ga. with the manual engine pump. Pull the gas line and put a Pressure ga. on the end and turn on the key watch and see what the out put is. You may just need a new gas filter it looks pretty old and maybe full of crap. Or just check the volume.By testing the flow in a catch can.. may 2cents
