FYI, the pump he pulled out was a John Hervey aftermarket special. I’m surprised it didn’t have the tuna can under it. He started selling those about 10-12 years ago.

Apologies to anyone living in that state.

That was a factory setup in there, not John's. You can see the stock pickup assembly and hose inside the tank. It appears the pickup hose broke and was repaired in some odd way instead of replaced. Clearly the repair didn't hold up, broke off and that's why it was cutting out. When accelerating, the fuel goes to the back of the tank and that pump was just sucking up air.

I'm surprised that mechanic didn't inspect the setup before ordering parts. With a system he wasn't familiar with, he really should have explored it first to see what needed to be done and then order the appropriate parts. I wonder if they will end up just getting stock style parts or go with DMCH replacement? The whole pickup assembly and sender have to be replaced.

I really enjoy watching his videos however was pretty annoyed with him using his feet to push open the door in the beginning "exercise" segment. Can only imagine all the grease and oils on the bottom of his shoes now rubbed into the door panel, thanks guy, not funny.

You sound like he did it to your car.

Well having people jump in my car at shows when my back is turned has made me a bit more cynical when I see others acting like this. He's the mechanic, not the owner, have some respect. Maybe if hoovie was standing next to him counting the reps like he was okay with it would have been fine, but if I saw some video of my mechanic acting like this with my car without my consent I'd be pretty upset.

You have to appreciate that this is all being done for entertainment value. As such, things will be done differently. Hoovie was probably there during the filming and editing and this is how they wanted to do it. Usually this stuff is all rehearsed and they had seen the mess already. For all we know they could have done multiple takes.

I’m 99.99% sure the small diameter pump assembly with the thick rubber hose used as a filler between the OEM style boot, is a Hervey product. You can clearly see the rubber filler in the boot when he is examining the deterioration. It’s likely the PO just wanted to keep the OE baffle assembly and chose to cobble it together to make it work. I have not looked on Herveys site for a couple years. He may not sell that pump assembly anymore In lew of the GM pump modules being used these days.

Edit: I just looked on his site. He doesn’t appear to sell it anymore, but there was at time period that he did back when the supply of direct fit OE pumps had become scarce.

This is some strange white knighting.

Now that I'm home and can look at the video full screen, I'm still not sure it's John's pump. He had the "power pump" which was smaller then the factory one but wasn't intended to go to the stock pickup line. Here's a pic:

Notice how it has a tall neck a that the top while the one in the video doesn't. The video also shows some sort of bolt like thing right above the hose clamp on the bottom. Even if it was John's pump, it wasn't installed properly. Interesting enough, I see the additional boot that was added to adjust for the size difference looks to be in great shape. It's the factory boot that's turned to gum.

I have his other fuel setup that uses the factory pump and boot but has a pickup screen directly fitted to the bottom of the pump and a different return line that sends the fuel straight down. The baffle is not a tuna can baffle either but something he made (Bill R was the one that used an actual tuna can). I put it in over 12 years ago and it's been running fine ever since. With that setup, there was nothing to really break down (the adapter between the pump and pickup screen was a friction fit piece made out of solid plastic).

[DMC5180]

Thanks for refreshing my memory as to the originator of the tuna can setup. I had forgotten about Bill R on that one.

Not sure that set-up is even an old SpecialT item. It is possible whoever did that work just found a pump and made it fit and never ordered anything from any of the Delorean vendors. In any case it really doesn't matter since it is all garbage.
