fuel pump in tank/frame mount

I have a fuel pump for a 88 k5 blazer, and im just trying to figure out if i got a in tank pump or a frame mount (is there any distinguishing differences???????). Since the k5's came stock with the frame mount electric pump i didn't think to specify frame mount when buying it from advance auto parts. Also im just wondering if an in tank pump can work out of the tank, im sure thats a stupid question.

thanks
patrick

I thought the "in tank" pumps were cooled by the liquid surrounding it, think you might want to ask an expert tho...

Snoop,
you do not want an in-tank pump. Its a PIA to replace if it fails, especially when youve got a full tank of gas. Do your self a fav and keep the external fuel pump. I speak from experiance...I had to replace mine in my Yukon

my first questions might have been confusing.

1. I need a frame mount pump, or any electric pump that is NOT in tank.
2. I wanted to just run the stock TBI pump, but the instructions on it make it sound like it is supposed to be in tank...even though the truck runs a frame mount pump.
3. I will be running a fuel cell, so i was just going to buy the stock pump b/c it is frame mount(should be for the tbi350 on a K5 blazer), but the one that showed up in the Advance auto parts store makes it sound like it is a in tank pump. (as i said, K5's should use a frame mount)

So, what im trying to figure out is what type of pump i have...is there any distinguishing differences in looks of the two pumps.

I need an electric pump frame mount/out of tank that doesn't cost $100 dollars+

If i had a k5 around me i would just go look but i don't.

TIA

If it has a inlet hose on it it should be a frame mount.......right??
A in-tank would have it's own pickup ( because it is inside the tank ).....

As far as I know K5s never came with a frame mount pump. I added fuel injection to my 85k5 and every listing I found for the tbi years 87-95 was a in tank pump. The replacement pump I checked out from pepboys did have an inlet also but no pickup so be careful before you mount her on the frame.

Actually I have a similiar question. My uncles F150 is Fuel injected and has an in-tank fuel pump. Not sure on the year but I am guessing late 80's. The tank is rusted through and is leaking pretty bad. He wants to take the gastank from my parts truck (87 K20) and put it on the F150. I was wondering if we could just pull his intank F150 pump and mount it up to the frame. or would overheating be an issue?

well i figured it out, the k5's are not frame mount.

i picked up an fuel pump off of an 88 f150 with the efi/mfi 351. They run an intank pump and a frame mount pump, so i guess you could just find a tank with an intank pump and use that and run the lines to the already frame mounted electric pump...i assume you should be fine.

also the part number was E2000, another pump that works is E2182, don't know the vehicle it comes off of though.
