Anyone using the Tanks Inc. sump with in tank fuel pump?

[Joelk]

How effective is it?

How difficult is it to install?

Please provide as much info as you can about it?

Thanks, Joel

I have it on my car.

I rebuilt a stock tank, it inviolved some work and fabrication. The pumpunit itself is just a bolton deal if you have the tank made for it.

In my case the pump is somewhat noisy when the tank is less than half-full. I think it is the tank itself that becomes a resonancebox.

Jan, thanks for the reply.

Aside from the noise, does it work well?

Does it ALWAYS keep fuel at the pump?

Has it ever lost fuel pressure, and if so, under what conditions?

[jannes_z-28]

It works well and there is a small tray that keeps the fuel around the pickup. Haven't had any fuelsurge problems and the car has been driven real hard on track several times.

My engine is a stock LS1 from 2001 Camaro SS but the pump should handle more than that.

Is anyone else using it?

i have the unit, but have not had it on the road yet. i've had it submerged in a temporary fuel container for break-in stand.


...In my case the pump is somewhat noisy when the tank is less than half-full. I think it is the tank itself that becomes a resonancebox..

right... it must be the vibration through your tank or something. on my break-in stand, i have it in an unsealed fuel container, and i could not believe how quiet it is. with motor off, couple times have had to look at pressure gauge to make sure pump is going.

quality of components seems great, and for me it was the perfect solution for keeping a stock style tank. the fuel return is directly back into the sump tray. with proper placement in the tank, hard to imagine dry heaving unless you are almost empty.

I havent had mine on the road yet either but it starts and runs just fine, i cant comment about the noise either, my car has open headers at the moment so i dont really hear anything else when it is started!!!

Here are a few pics

Thanks for the replies.

TA219 I checked out your photos. Looks great except.....

The Tanks Inc. instructions recommend mounting it all the way to one side (left or right does not matter on a street car)with the "feed hole" pointed toward the other side. Till I read the instructions I did not recognize the benefits of installing it to the side, and I was planning to install mine near the center of the tank. Now that I have read the instuctions I think I understand the advantage of mounting to one side or the other. If you mount it on the right, turning right it will be dependent on the fuel in the tray but if you turn left it will get pleanty of fuel from the fuel "sloshing" to the right side. Mounting it in/near the middle will take away the "fuel sloshing advantage".

Why are you installing it near the center of the tank?

[TA219]

Joelk..... honestly.... i must have missed that part in the instructions. I had seen others on LS1 tech build their tank the way i did, and at 1st glance it looks like the ricks tanks are built the same way http://www.rickshotrodshop.com/main/caqmerost.jpg but there may be a bunch of baffling or something inside.

The idea you bring up makes perfect sense though, I guess i could correct my mistake by simply rotating the fuel pickup 90*, that would put the tray all the way to one side, if that doesnt work then i might have to be careful about letting it get too low on gas.

This is my 1st build so i figured i would make mistakes like this.... live and learn :)

[Joelk]

Like I said, I did not perceive the benefit until I read the instructions. In fact, I almost started cutting a hole near the center of my tank before I read the insturctions.

I don't think rotating the "sump" 90 degrees would help much. It would put the "fill hole end" toward the side of the tank, not the pump. It might help slightly but you probably would not get the full benefit that would be acheived by putting the pump near the side of the tank.

It probably does not matter 99+% of the time, after all it only provides a benefit when you turn one way and if the "sump" has adequate capacity it may not make any difference at all.

It looks like you have done a great fabrication job. I would try it see how it works. I bet it will be fine. I doubt it will ever create an issue, and if it does, it would probably only be if the tank is very low on fuel.

Do you have any idea what the baffle/"sump" looks like in the Rick's Hot Rod Shop Tank?

[Fillpot]

I installed one in my 69 camaro tank and works fine.THANKS

I dont, but i am curious now!! Maybe someone with a ricks tank will chime in

I installed mine last weekend. Here is a link http://forums.performanceyears.com/forums/showthread.php?p=3281729#post3281729 to some info about my install.

TA219 - I ended up putting mine in a position similar to where you put yours, except that instead of putting a recessed area in the top of the tank I lowered the tank to provide clearance for the fittings/lines.

I did a similar set up with my 2nd gen camaro. I used a sending unit from a tbi caprice, it had the same tank flange, sending unit style, and return lines, with mount for a pump. I then cut out the bottom of the tank and dropped a 10" square sump 2" down from the bottom of the tank and 3" up into the tank with some holes so fuel drains back into the sump. It works really well, I autocrossed with about 3 gallons in the tank. i also drove home one day and it died going over the speed bump. I drained the tank and there was about 1/2 gallon, that is sweet!

Keith, it sounds like your doing something similar to my plan B. If the tanks inc. in-tank sump does not work well enough, I will create a sump and drop the fuel pump into it similar to what you have done except my plan(tenative) is to just make a hole large enough for the bottom of the tank for the pump to fit down through. That way the fuel will be pretty much trapped in the sump.

So far (I have not driven it much yet) the T/I kit seems to be working fine. Unless I find it deficient at some point I will stay with plan A.

I have one in my 69 camaro. I mounted it in the middle of the tank so I could bring the lines out the stock path. I had to cut a hole in the trunk to get it to fit. I need to make a cover over it in the trunk. The unit works well. Have had no starvation problems. I did mount the sump sideways because the the tank angles up going backwards and it wouldnt have laid flat. I filled the tank with soapy water to reduce the danger of fumes exploding. Cut a hole with a jigsaw. My stock sending unit went out so have ordered a DSE unit. Good luck

Keith, I know, bringing the thread from the dead. But how has your 2nd gen tank been working out for you. I have a g-body wagon with a turbo 6 I am redoing the fuel system too. I am thinking about a external surge tank, but I also tossed around putting a sump/well similar to what you said you did.

Thanks
