Fuel from rear tank
I installed a Blazer tank in the rear. Manual fuel pump to a 600 Edelbrock carb. My problem is that after sitting for a few days it appears the fuel line is running dry. It takes lots of cranking to get to fire up. Anyone else notice this? I have thought about some sort of one way valve to install inline.

Re: Fuel from rear tank
Very good question. I'm about to do the tank relocation, and never thought about that.
Was this an inherent problem with the Balzers and Suburbans? |

Re: Fuel from rear tank
This is common with the Edelbrock carb. I don't think it has anything to do with the tank location. My truck did it with the stock tank too.

Re: Fuel from rear tank
I suspect the fuel pump is bleeding off the fuel. I had an inline six ford that would do the same thing .

Re: Fuel from rear tank
Put an electric fuel pump in line near the tank. Electric pumps push fuel not pull like a manual.put it on a separate switch and run it a few seconds before turning over engine and you will have fuel to your manual pump.

Re: Fuel from rear tank
You could install a check valve just behind your mechanical pump ( toward the tank ). That should keep the fuel close enough to minimize the time to prime things again.

Re: Fuel from rear tank
I have the same problem on my rear tank, planning on a electric fuel pump close to the tank turn it on by a switch and after truck starts shut it off.
