[jonasson]

Hey guys, getting a 60 chevy stepside up and running, the 5.3 ls and 4l60 are all in but im debating on putting an efi pump in tank, what are your thoughts on this, i really dont like inline pumps cause they are noisy but then again i may be wrong.

Best Regards

Jonni.

That would be a pretty involved engineering and fabrication project, not to mention that you will have a lot of fuel flowing in and around the cab. Are you thinking of using a late model OE type of pump? Those require relatively shallow tanks, and even those would be on the noisy side operating inside the cab.

I use this pump mounted next to my under bed tank. it's isolated on poly mounts and I don't really hear it.

Ahhh i understand, what are your thoughts on an inline pump then? noisy??

Some are noisier than others. My MaganFuel pump is quieter than most I have experience with, but it helps to use isolator mounts to cut down on the vibration resonance through the chassis. I had an Aeromotive A1000 before, and that pump made a lot more noise.

I did it in my '65 daily driver with TBI 305 ending. Look at my build thread. Wasn't that complicated, I used an extra sending unit for the new supply, cutting off the float assy.
Used new sender(needed it anyway) for return, cut off pick up tube just below the sender assy.

Would be glad to pass along more detailed info on how I connected the electrical parts, etc, if you're interessted.

Tincan-
Were you able to hear the pump from the driver's seat? I wonder if you used a sound deadener (Dynamat, Fat Mat, etc) on the tank whether it would make a difference. I would have to say that it wouldn't hurt....

..edit: It looks like in your last picture that maybe you already beat me to the punch. Is that a sound deadener I see on the tank?

Yes, that is a high density foam rubber-approx 3/8" thick. I covered both sides of the tank and the rear wall of the cab. Also not shown is the muffler sleeve that came with the pump, I used it too.

There is somewhat of a high pitched whistel or wine, but I really think it wouldn't be that bad when driving(with road noise, etc.)

In my build thread I commented about the noise, but, I found out when I was removing it, that I had the pick up tube bent a little too far forward and the pump was hitting the tank inside.

I used and Airtex OEM style replacement pump and screen from a '91 Olds Custom cruiser- which was the engine donor.

I also used the insulated terminal that was originally for the sender for a power feed, adding blade style connectors to the bottom. For a ground I driled a #10 hole thru sender, attached ground from pump with ring terminal. Fastened that with a lock washer and nut, then ran another wire with ring terminal from that to the body, adding a second nut on the ground "stud". I made it serviceable like the OEM- pull sender, unplug pump, replace pump and plug in. Install sender.

Side note: I have since relocated the tank to the rear, for two reasons, I wanted the extra room to move the seat back 3" and up 1", and my daughter didn't like it behind her.

I am working on modifying a sender unit to make it a single piece, sender and fuel pump.

tincan1966 i like the idea of intank pump, also fuel surge etc.

i looked at this unit from tanks inc and it seems easy as pie.

Thank you so much everyone that pitched in on this matter.

jonasson: that is a good looking kit! I believe that would fit in the flat spot where I mounted mine, as well. You would just have to bend the tubing, close to the flange in order to match the angle of the tank. Mount it beside the sending unit and you're in business. Thanks for posting that find!
