Anyone have any beta on installing these in vehicles without aux fuel tap ports on the fuel pump? Wondering if its possible to T into the fuel lines somehow- the thought of removing the fuel tank on a 2015 Canyon to access the fuel pump and drill a hole through it or the tank sounds like not fun.
Espar B4 gasoline heater in truck without aux fuel tap?

Don't remove the tank. It's almost always easier to leave it in place and remove the bed. Get a few buddies to help, it's really easy and you can have it unbolted in probably 10 minutes, unplug the lights and lift it off.
A T into a fuel line wouldn't work either. The pump is in the tank and you would be drawing through the pump and check valve. I bet it would run a little while but eventually suck the fuel line dry until the next time you ran the truck. Plus it would feed the Espar high pressure fuel each time you ran the engine and I doubt the Espar would like that.

It depends on the truck and tank. I can get the tank off my Tundra in about 10 minutes. I have a lift though.
Raise truck and put table under tank
Lower truck to where tank is resting on table
Unbolt and lift truck off tank, tank is left sitting on table
It all depends on vehicle and setup though.
I have also heard that T'ing off fuel lines for these heaters does not work well.

You're not wrong but you can probably get the bed off in 10 minutes too. No disconnecting fuel lines or wiring plus for this application, everything remains sitting there as it is installed so you know exactly what you're dealing with in terms of clearance and routing for plumbing.

I'd be a little worried about water intrusion.

You have to do the same thing except you don’t have the liberty of removing the bed for access.

When you’re dealing with a fuel tank that you can’t or don’t want to weld to, you can install a bulkhead AN fitting just about anywhere you can access the inside of. The fuel pump assembly or right next to it is usually perfect. Then run a small piece of hose or line down to within a couple inches of the bottom of the tank. That way you can’t empty the tank by running the heater. Use a dowty seal or sealing washer under the bulkhead fitting to prevent leakage.
