No telling really. With either one.

My 93 has 40k on the clock' stock lift pump.
So 40k+

But also for example look at all the electric fuel pump vehicles that go couple hundred thousand.
Really comes down to personal preference.
Pros and cons on both. Mainly pros for electric, but that's besides the point. Lol

Most if not all cars & trucks today come with an in tank fuel pump because the engines are fuel injected. But wait.. There's more... Its recommended you do not run the tanks nearly mt. the fuel in the tanks acts as a coolant for the electric in tank pump. But in the end it really is your choice to run them well past the dash red light. So you end up burning up the pump. Now you find out the cost plus labor to install it.

Yep. And most of the new ones you have to get the whole assembly.
But far as running low, that's true for any electric pump.

After reading many of the thoughts on the subject, at some point I'll be going with an electric pump. The main reason why, is I've already just replaced my mechanical pump, that was leaking. However, when I did it, I was also replacing the thermostat; so access was 'eased' by having topside access. It would seriously suck to have to do this from below just from the diesel alone.

The idea of having a topside electric pump, mounted on the fender behind the battery would make future work, way easier.

Im using the stock in tank pump of the truck im doing a diesel conversion on. Im using 2 regulators to get it down to 9 psi with the engine off. One regulator is a bypass type and the other is a non- return style. I have it operational as of now.

Just an fyi, I ran stock pump for a year on WMO and switched to electric because of prime issues (Mr Gasket green) that only lasted a couple of months and went back to stock. Oil if not diluted is ******* pumps, but the stockers do pretty good. I still like the electric better but need an oil friendly one. Until then the factory pump is a tried an true answer.

From what I've heard the mr gasket pumps are junk anyways and don't last long on Regular diesel
So wmo is thicker glad you got a month out of it

I've got a 100 gallon tank mounted in the bed. It's got fuel, but not hooked up yet. I've been thinking about this a fair amount lately. I'm thinking about just ditching the factory tanks; since they can be a pain.

What I'm thinking about doing, is just running to, and from the Transfer Flow tank. I need to find a replacement sending unit that'll fit the tank..... Here's the cool part, at least to me, is I can hook it into a key on source, but also put a concealed switch electrically between the keyed power source, and the pump. Mount the switch up under the dash, or somewhere handy, and out of view.

I can leave that switch closed for the most part, but say in a crappy part of town, or just not in the best areas, open that switch. I'd think it would be a fairly decent anti-theft device

Only thing to remember is you'll create return line pressure by putting it up high.
