Solid input. My experience with external pumps is on vehicles that are trailered to/from their location of use, which isn't the case for your 40 or mikes 40. I'd still want easy access to the top of the tank to get the in-tank pump out without dropping the tank.My $.02 here
I’m going away from running a frame mounted external pump. Yes, they are very easy to change. That’s good because I believe I’m on my 7th one at this point. Not cheap junk either, I’ve been through Mallory, Bosch and AEM.
I suspect (and a local hot rod shop owner agrees) that they simply get too hot and essentially burn up. Hot rod guy stated he used to use external pumps on customer builds but absolutely will not now because of reliability
It will require cutting my current tank up and welding it back together (primarily to address the complete s*** awful baffling in the Australian long range tank) but also to convert it to an in-tank Aeromotive Phantom 340.
All OEM’s run in-tank pumps which are cooled by being submerged in the ambient fuel. And they last and last and last. Yes, it sucks having to drop your tank to change a pump. It also sucks being stranded for 5 days in very northern BC because your external pump burned up, again.
Last one that burned up was in Nevada after leaving the Rubicon. Didn’t have my spare anymore because I gave it away on the run, to someone else who’s external pump burned up. So yeah. No more external pumps for me
