By putting the pump in above the tank. you are putting excessive duty on the pump to try and suck or pull fuel into the pump. This is one of the reason many inline pump will have a short services life and incressed failure rate.
It is just note recommened.. read the instruction that came with the pump.

Why is that all the low pressure pump would be doing is keeping fuel to the high pressure pump. If anything I could see it helping the the high pressure pump in that it already has a positive fuel flow to start with. Remember also we are talking about a less than ideal situation to begin with. If it was an option I would definitely run one the high pressure pump below the fuel level.
And where would you be putting the low pressure pump.. ?.. above the tank again ?.. His issue or question is about putting the pump above the tank.
Seem to me, same issue with either a High (EFI rate) PSI or a Low PSI pump would still have the same issues if being mounted above the tank. Let not get away from the original question.

Ok earlier I partially retracted my statement. I was thinking that he could use a small low pressure (mr.gasket makes one that's about 2" long) pump mounted lower to get fuel to a larger high pressure pump (such as an A1000 about 10" long). I later said that if you could use the small low pressure pump you could prolly find a high pressure to fit in that spot, so kinda making it a moog point. I apologize for any confusion this may have caused.
So yes you can mount it higher but not recommended, prolly causing premature pump failure as bczee stated earlier.
