fuel pump solutions

[BionicCruiser]

got some parts/ideas for fixing the fuel issues in my 40. Dumpolina's buddy used a Taurus fuel trap in his Samurai. Dump, did he have to cut open the tank to fit it?

I got a caprice tank from u-pull that had the same engine my 40 has. here is the fuel trap once I cut open the tank-

it's big. like 14" wide x 10" long and 4" high. I have to cut a big hole in the 40 fuel tank to get it in there and then cut/graft on a new hole to mount the fuel pump. not sure if there's a better pump bracket to use. but this one allows the use of the chevy level sender. last pics shows that relationship.

Steve built the tank around the "trap" and pump ... I'll PM you his contact info

Could you define your problem? Were your issues when running flat, on hills, wide open, bouncy, side layover, idle....etc.

I'm not sure what was happening for you to focus on the fuel trap.

My tank is a simple tank with a sump. From the bottom of the sump to the inline gas line, runs to the filter, then I have a high quality pump into a pressure regulator (I have an LS1). From there it runs to the fuel rails and I have a return to the tank. If I get on a super incline for a long time it's time to get to work because the sump will run out eventually.

I know guys who use the Walbro fuel pickups, they use a couple of them and they dangle into the tank and move when the buggy moves. if you use 2 you can be sure you get fuel at any angle. Walbro makes a new mat that I think is pretty expensive.

I have a low pressure pump that feeds a surge tank under the driver seat. high press. pump takes the fuel from it to the engine. return line goes back into the surge tank and overflow goes back into the tank. best I can tell, the fuel in the surge tank heats up and kills the high pressure pump that sits on the frame rail. other possibility is the low pressure pump can't keep up and the surge tank runs empty. either way, the surge tank is hot to the touch in short time and the hp pump is too. nearly too hot to touch. exhaust isn't too close, but does run under the surge tank about 6" away and under the floor. that's the closest point. it ran for years like this with no problem, but is now killing pumps every outing.
I want to have an in tank pump. that will keep the pump cool. the above suggested stuff is what I've found in my research. so, this is the route I'm looking at for now to see how it works. if no go, I will look at custom building a tank.

I'm running the stock tank with an external pump that is mounted behind the Tcase on the cross member and a regulator that is mount on the fire wall. I used 3/8 brake line to run the fuel line on top of the frame using as little rubber fuel line as possible. I've probably got about 8 mouths of run time around the city with a little off road and so far so good. I used to cook pumps pretty fast in the engine compartment and didn't help that I didn't have a regulator but my current setup is working good!

Here's the pump I'm running:
Aeromotive 11109, Aeromotive In-Line Fuel Pump | Aeromotive

I think the only thing I would do differently is move the regulator next to the pump and only run the fuel delivery line up to the carb. That would help keep the fuel a little cooler and clean up the install a little.

that's 1 thing I forgot. thanks for reminding me! I do have a fair bit of rubber fuel line. that is supposed to collapse over time at the bends and cause problems. I only have 1 section that is rubber, the rest is hard plastic line from the Caprice the engine came from. I will look at replacing that with a steel line.

I will look at replacing that with a steel line.

Go steel and don't look back.
