Care to speculate on tbi fuel system plumbing?

[Overland]

I'm attempting a minimally invasive installation and would like to leave my fuel tank alone entirely. The idea I have is to install a filter housing on the inlet of a frame mounted pump, and to route the return line to the inlet side of said housing. Most mechanical diesel engines I've been around were plumbed this way for injector pump cooling.

I've been away from here for some time, but I recall discussion of fuel heating through pumping it across the regulator and speculation regarding an inline cooler to remedy the condition. My tank is going to stay behind the seat, and is only plumbed for suction, of course from the top. I think routing to a filter would be quieter in the cab and wouldn't heat the fuel in the tank, if the pump can pull fuel across a filter after lifting it up the pickup tube.

I feel like once primed it should work, but you could fill a warehouse with things I don't know. Please alert me should it seem my logic is not firmly based in reality.

Thoughts, ideas, options, and experiences about remote mounted fuel pump and return fuel locations vary between members.

Frame mounted fuel pumps are OK. In-The-Tank mounted fuel pumps are optimal. Routing the return fuel to the bottom of the fuel tank is optimal. . . just like factory.

Some fords use frame mounted pumps. Just make sure it's lower than the tank and not mounted were it would snag anything. I personally don't see fuel heat being an issue with a return line you are not very likely to vapor lock. That's my $0.02

Ford to my knowledge utilized a fame mounted booster pump to supplement the in tank pump in the 80s, where a truck with two tanks had three pumps. In my admittedly minimal experience there, the booster won't work on its own, or at least not sufficiently. That is, pulling fuel through a dead pump in the tank.

I'm considering something like the Carter P5001 suggested on the swap info page here. I'm not a fan of remote pumps, but with the tank in the cab, I'd rather not listen to it. I know someone likely sells a bolt in solution ready for an in tank configuration, but I'm also operating on a minimal budget and would prefer to maintain any original parts I can.

I have a picture in my mind that looks very clean, but that doesn't matter much if it doesn't work. I figure this is the best place to hear of other's trials and errors.

This is in a 62 C10 if it assists with your visualization

I was thinking of the van pumps that you can buy one at the parts store for about $60 usually in stock, pretty sure it's for single tank configuration and has barbed fittings on it. I used on on my motorhome to get it parked when the in tank pump died. These are made for 90 psi 40 gal per min and economical. I don't think you would have a problem with one using the cab fuel tank, as gravity would keep the pump primed plenty easy enough.

Cheaper than the Carter for sure, similar in appearance, like an in tank pump with barbs. The Carter has threaded ends making barbs optional. I'm imagining a soft line between the hard line where it exits the floor and the filter housing, then hard line to the pump, and preferably utilizing the original tbi fuel hoses from there.

Would the fact that the fuel tank utilizes a pickup tube from the top cause difficulty priming at low fuel levels?
