Discussion
I mentioned in the other fuel thread that my lifter pump, Holley Blue Top, started to lose pressure over the weekend, this affected the HP pump and I also lost pressure in that down from 60psi to around 20psi, it then cut out but fortunately we were about home!
My question to people who have LP lifter pumps is what have you gone for and why?
My pump has lasted for about 3 years but I suspect it's where it's positioned that has made it fail, so before I replace like for like and maybe suffer the same experience I would like to look at all the options.

I suspect my system will involve too many changes for you but this is what I have got.

It is mounted in the passenger side tank in place of the fuel level sender and pumps up to the swirl pot mounted on the tank. It pumps up and out of a new cap I made for the sender fitting and into the swirl pot mounted on top of the tank.
This then feeds straight into the A1000 Aeromotive HP pump (also mounted on the tank) then via a fine filter into the fuel rail and out again into the regulator and then back to the swirl pot.
Both tanks are linked using both bottom fittings and the swirl pot feeds back to the same tank as the LP pump is mounted.
Probably not much use to you, but there you go.

The main reason I went this way was to avoid switch over valves and the noisy LP pumps

Well I've been out to strip the system down and my LP pre filter was blocked, could just about blow through it, so no way was fuel going to go through it by gravity, I now wonder if it's the foam in the tanks?
I put the pump back and ran it a while on its own but it doesn't sound great.

Interesting what you have done there Paul, it wouldn't take much for me to do that. I have the tanks linked by -12 at the bottom, I have the -6 outlets connected as well, as they feed the LP pump at the moment. I have the swirl pot on top of the passenger tank, I have a Bosch 044 on the floor down by the passenger tank. maybe get a swirl pot made to house the HP pump.I suspect my system will involve too many changes for you but this is what I have got.

I don't want to make another fuel thread so if I do anything I'll take over to the other thread.

I'm trying together away from that type of pump, I have too many in the garage
