There are plenty of electric fuel pumps that go way beyond the flow rate of the oem mech pump
Please list them if you know of any because if I ever go with a bigger injection pump I'll probably have to go electric, or do an arm swap on a high volume 460 pump (original plan)
Also the facet duralift im looking at right now is 33gph
Which is 3 more gph than the mechanical pump the van had on it
Check this out at Amazon.com 40222 Facet Dura-Lift Fuel Pump, 12 Volt, 9.0-11.5 PSI, 33 GPH https://www.amazon.com/dp/B076XHKG2Y/ref=cm_sw_r_other_apa_i_kyxdFb57PDEES
Had to have it running immediately
so bought locally
No i feel my anoos
cause i paid twice that
Im down to attaching the plumbing to the pump and wiring it up
Well, maybe this aspect of the mechanical lift pump has been covered elsewhere but will add a comment to this thread concerning my experience with the mechanical lift pump and an observed weakness which i don't see discussed-- worn out drive eccentric/ cam lobes. I am into my engine and discovered significant wear on the lift lobe of the fuel lift pump drive cam-- enough to perhaps degrade the pumping ability of the mechanical pump. And the bummer is that these items are no longer available from Ford or International; did find a NOS source but prohibitively expensive at $250. So appears alternatives are go electric (which I probably will be doing) or try finding a cam grinder to build up the worn lobe and regrinding back to original profile.
Wondering if anyone has gone the regrind route?
And wonder if there are some users of mechanical lift pumps that unknowingly are fighting a "flat" cam lobe which is contributing to their lift pump problems??
Mine was definitely worn. I found this out after having to pull a brand new mechanical lift pump off twice, trying to figure out why it would pump by hand, but not on the truck. I wound up bending the lever on the pump to give a little more travel, and she fired right up. Worked good, for about six months. I’m done with it, I’m going with that Facet reefer pump.
Ok, sorry to intrude on this but I got an odd question... i know this post is about converting to an e pump, but I'm currently doing a 6.9 diesel conversion from gas on an 82 f250 and was wondering if I can leave my gas fuel pumps and plumb it to the back of my lifter pump? Letting the gas tank transfer pumps "prime" the lift pump with pressure. The question really is, how much pressure can the back side of the lift pump handle? If the gas transfer pump is an over load of pressure can I plumb in a restrictor or a regulator with a bypass, allowing the fuel pump to pressure up behind the restrictor, and only feeding the lift pump the pressure it can handle? Maybe this is an absurd idea but I know very little about diesel, and I'm just curious/competent enough to be dangerous. Thank you for any input on this and sorry again for the intrusion/hijacking.
82 should have been carbureted and not have in tank electric pumps.
Yes it is carbureted, but in all honesty I know very little about these trucks. Is there just a sending unit in the tank to deliver fuel to the carb or some sort of transfer pump to get it there, or is it just a low pressure unit like the diesel and would be redundant to use the gas when I have the tanks for the diesel anyway?
i believe it just has a pickup in the tank and a engine mounted mechanical fuel pump.
but it makes no difference, if you are going to diesel you will have to pull the tank to at least add a fuel return which the gas engine tank will not have.

When we say "pickup" is that similar to the gas transfer pump of a sorts or is there a difference in how they function/pressures behind it? Now Is the return line part of the diesel pickup assembly or is it a mount on the tank? If it's a mount on the tank, and the pickup/transfer pump systems are similar can I put the gas system in the diesel tank? If this makes no sense or is redundant I apologize, I have very little/no experience with diesel systems.
the fuel pickup is part of the sending unit. it is a metal tube that goes close to the bottom of the tank, then has some type of a filter element on it.
the fuel return is usually part of the sending unit assembly too. a pipe that just returns unused fuel back into the tank.
the fuel pump draws fuel out of the tank through the pickup tube, sends it to the diesel injection pump, which then sends it out to the injectors. on top of each injector is a return rail system that collects the unused fuel and returns it back to the tank.
