Fuel pump location

What do you recommend for an electric fuel pump location? External on the frame rail or in the tank?

I'm learning, I hope. I got a new tank from tanks inc. in my 34 Plymouth. Dual quads on a rebuilt 354 Hemi. I was running a new electric fuel pump near the fuel tank but it had to be mounted high in the frame rail. It seemed the carbs were starving for fuel and now the motor just doesn't get any fuel. Pulled the pump and it's probably burned up from running dry.

There is no location on the frame rails that is lower than the bottom of my tank so gravity feed to the pump isn't ideal but the bottom of the frame rail is below the center line of the tank and lower than where I previously had it. I could also get an in tank fuel pump but I need to make sure my tank can run one.

So what do you think? Replace the external fuel pump and mount it as low as possible even if it isn't below the tank or get an tank mounted pump?

 

I have an electric pump on my T Roadster. The fuel tank sits low in the ch***is and the pump sits on the side of ch***is rails near the top of the fuel tank. The trick is to make sure it does not run dry and the closer you have it to the tank the better.

Some of the new car fuel injection systems require in tank pumps. Perhaps you need a pump that sends a higher volume better fuel pressure ! If you have a new tank did you ask the supplier of that tank what type of electric fuel pump they would recomend for your application ?

 

I just put a new " Tanks " gas tank in my roadster. I had a Holley red pump on the frame rail but bought an in tank pump when I got the tank. That's the way to go. Good fuel delivery and not nearly as loud. The people at Yogi's in Iowa are super nice. I live about 80 miles from them so I took a drive and got to see the new shop, very nice.

 

Thanks for the advice. I will call them on Monday an see if the tank I have can use their in tank kit. It has the auxiliary cover but I'm not sure if it has the internal tray. That's why I was thinking about sticking to an external pump.

 

If you put it in the tank make sure you make easy to change and you should never have any problems with it.

 

If I was impatient and wanted to go to NAPA today could I get a hanger and pump that would work in this tank? It would go into the 6 bolt accessory opening. I think the hanger depth and tray are the issues.

 

I called Tanks Inc. and it turns out my tank cannot easily take the internal fuel pump. I would need to drill a hole to accommodate their kit. I'm not going to do that. So I need to figure out how to run an external pump. Previously I had the pump mounted too high and as I mentioned the frame rails near the tank won't allow me to mount the pump low. Even if I mount the pump on the inside of the frame rail ahead of the axle the lowest I'm going to get is near the height of the bottom part of the tank but not below where gravity is my friend. So my HAMB friends, what do you recommend?

Should I fabricate a fuel pump mount lower than the frame and close to the tank to get gravity feed to the pump? This seems unsafe to me.

Should I mount a pump ahead of the rear axle as low as I can in the frame?

What electric fuel pump would you recommend in these cases?

 

If you could give me a few, i know there is new in tank pump kit available that is really good. i don't remember where i saw it though, but i can probably find it tomorrow.

i don't think there is anything wrong with an external pump, but with an in-tank you get extra safety(crash protection) and the pump will run cooler.

 

In tank pumps are specifically for fuel injection cars, 30 PSI to 60 PSI.
A good fuel byp*** pressure regulator can be used, with a return line to the tank if using a 3.5 to 5 P.S.I. carburetor system. The high pump pressure remains high, with the regulator byp*** going to the carburetor.

Get this: I live in CA., Central valley. My F100 tank was at the radiator guy's shop, I have a 32 P.S.I. Nascar pump; so I ask him about welding a bung on top of the tank for a return line. He looks blankly, and says, "I've never heard of that before..."

I had a friend do it.

 

Hot Rod has an article about a new pump set up. Keep your pump protected inside the frame area. Locate the pump so it can get some help from gravity as you said. Mount it side ways long ways anyway you can to get it low as you can but to be where it won't get hit from something off the road.

 

I always mount mine on the frame rail. This way its easily accessible, and if it ever ****s out on the road all I need to do is go to the nearest auto parts store and they have them on the shelf. Real easy roadside fix, couple hose clamps and a couple **** connectors and your back on your way.

What are the odds of a Vatozone having the intank electric fuel pump you need?

 

Use an OEM intank fuel injection pump. Cheap and dependable, also quiet and cooled by the gas in the tank. As said above, regulator and a byp*** line back to the tank. Ya, all the parts stores have them, but how many times has your daily driver newer car puked a fuel pump? Good for 100,000 easy.

 

I used a Carter 4070 pump forever, on several cars, I mount mine on the driver's side inside frame rail just ahead of the front spring perch. been workin' well for me.

I went with the Carter 4070 mounted ahead of the axle on the frame rail. Works great but it is a little noisy. That doesn't matter much when the car is running. I need to wire in an oil pressure cutoff for the pump. I don't think my Hot Rod wiring harness does that.

 

I use a 5# oil pressure switch...Can be purchased from Summit or Jegs, Instructions are good. Check 'em out.

I love the early electric fuel pumps of the 60s. None were tank mounted. They are iconic images that belong on old hot rods IMHO. Many people want to hide they essential parts of a car, I like to show them off.

I could not find a picture of the green box electric pump that was so popular in the 60s.
