So I've heard rumors of this fuel pump and have some questions. After doing searches throughout this forum I know there's a low pressure pump inside the tanks that is used to prime the high pressure pump. Do you guys think the high pressure pump has enough suction to work without the in-take primer pumps? I read in one thread that a user didn't think it would but what's the general concensous?

How much distance is there between the pump and the gas tanks? What if the inline pump was moved to say 9" of line between it and the tank? Think that would help in the suction department?

I ask this because I'm actually fighting an issue with my Toyota truck that I've installed a fuel cell into. With my current setup an in-tank primer pump is not an option. I've plumbed it up with a pump that is recomended for what I'm doing but after tons of research it's a mediocre pump at best when it comes to sucking the fuel so I'm looking for an alternative pump and have stumbled on this setup that's found in the older F150s!!! I have a aftermarket billet aluminum fuel filter canister between my cell and the pump that acts kind of like a catch tank for gas for times when the pump looses prime in a corner or something but the fuel pump just can't recover from that. Typically when I encounter this I have to litterally pressurize the tank by litterally blowing on the vent line and capping it shut which forces the canister full. Also I have to break a fuel line loose between the pump and the engine to bleed the air from it. This sucks when it happens every 15 miles or so... My Toyota is a FI V6 so I need a high pressure setup...

I know you are ford people but some help for a fellow truck enthusiast would be greatly appreciated and your older F150s may have the solution I'm looking for on my '89 yota pickup... Here's some photos of my pile. I've built the truck myself in that little garage of mine...

Howdy yota!

On the '85 to '87 (depending on engine) - '88 fords, when the low pressure pump goes down the high pressure pump usually can't run the truck. Thats one reason why in '89 Ford switched to only high pressure pumps inside the tanks.

Why are you unable to run an intank high pressure pump?
