4.0 w/ Fuel Pump On Rail - Primer Pump?

[Neuner]

Been running with a 4.0 swap for about 6-7 years now. Used an e2000 high pressure pump with a pre-filter on the frame with no issues.

Recently had to drop the tank twice. With this last time, I've not been able to get it to properly syphon fuel to the e2000. I'm also worried for the day I ever run out of gas and not able to start it again without crawling underneath.

Anyone use a low-pressure primer fuel pump in front of the high-pressure unit to help syphon fuel? If so, how well does it work and which one did you use?
