Hello all. I am new to this message board. I have searched the web and asked all kinds of people the following question:
I am building a '68 Chevy C10 shortbed pickup. I am running a 350 K motor out of an '89 suburban with the factory Throttle Body Fuel Injection. I would like to relocate my gas tank to the rear frame rail area, and I would really like to use the in-tank pump and sender unit from the suburban.

1. Is the '67-'72 Blazer style gas tank sender mounting hole smaller than the '89 pump/sender?
2. Does anyone know if an '87-up full size Blazer 25 gallon tank will fit behind the rear end between the frame rails? This would be ideal, because the sender/pump unit would fit right in.

My research so far seems to show that side to side clearance will be fine, it is front to back that seems tight. The '87 tank is supposed to be just over 28" front to back, but the frame rail crossmembers are about 19" apart. Would it be feasible to move one or both of these crossmembers to fit the tank. Similar to moving the trans crossmember to mount the 700R4 I will be using?

Or, does anyone else know of another application that would allow me to use the in-tank pump/sender set up, or have another suggestion?


Any help or advice is appreciated
Thanks

On my 67 C20, I relocated the tank using an 83 Blazer tank and it fit good between the framerails and had plenty of room front to back but I have a long narrow bed. I used the straps out of the blazer to hold it up. Takes some measuring to get it right but once its done you will love the extra room behind the seat.

you can buy the whole dang kit minus a filler neck and wire for sending unit for i think about 380 from brothers. just cut out the little wimpy cross rail at the back and drill 2 holes and use the straps provided and away you go. It is a 14 gallon polly tank. Oh yeah it comes from brothers. It also has a new acdelco sending unit.

hey guys! Thanks for the info.

However,
Skylark, my 68 is a shortbed, so I believe the last two cross members are tighter than on your longbed. This is causing my front to back clearance prob. Do you think it possible to move
one or both of the rear cross members to make room? I need to gain about 7 or 8 inches.

I am aware of the kit you mentioned, but I would like to use the in-tank pump/sender kit from the 89 suburban. The kit brothers sells is a 67-72 tank with the sender only. Do you know if the sender mounting hole for this tank is the same size as my 89 pump/sender combo?

Someone told me the 67-72 sender only tank has a 1 7/8" mounting hole, whereas the 89 pump/sender unit fits in a 3 1/8" hole. Can anyone else verify this?
