In tank fuel pump with nipples?

I've dropped my gas tank ('78 CJ5) to repair the fuel sender. It turns out that the float developed a hole and filled with fuel. So that was an easy fix.

Since I have the tank out, I thought I'd chase another issue I've been having. I'm currently running an intank fuel pump from a mustang attached to my CJ sender. I think it's close to being on the bottom of the tank (20 gal. poly tank) but I still think I'm experiencing a sloshing issue when the level of gas gets low. The mustang pump is cylindrical with a screen on the bottom. I'm sure it's not FLAT on the bottom as the poly tank is angled in the rear, and my pick up has to have a bend in it. So I was wondering if there is an intank pump from a different vehicle that uses a nipple on each side. Something that I could put a hose on and be sure that I'm picking fuel up from the bottom of the tank.

Re: In tank fuel pump with nipples?

I'll have to pull it out but I think that the one frome my GMC van is like that but I'll have to look up the pressure again. I also think some Dodle Lasers and Omni turbos were like that also. I'll have to check my books.

Since you have it out, how about some pictures of your fuel pump setup.

I'll be doing the same thing if I put the V6 out of my van into my CJ.

What psi are you pushing out of your fuel pump? There's seveal options depending on the psi you need.

Re: In tank fuel pump with nipples?

The OEM 20 gal. fuel tank has a built in well and baffles in which the siphon sits. So, if you've got the siphon for the pump in that well, sloshing should not affect the fuel pick up. If you get so low on fuel that the well goes dry, no amount of suckin's going to help.

Re: In tank fuel pump with nipples?

I'm sure I looked inside my tank when I first purchased it. I don't recall any baffles or well. I'll have to take another look. But I'm sure my "pick up" is near the factory spot. It's just the fact that the pump is angled towards the bottom that is keeping the "sock" from laying flat on the bottom of the tank.

Off the top of my head, I'm thinking the pump is putting out about 35 lbs of pressure. It's a factory pump from a '90 mustang. Nothing too high performance about the motor, no unusual requirements.

I've re-installed the pump in the tank. So I'll have to pull it to get you a good picture of it. Not a big deal, I'm just not in the habit of tinkering during the week. I'll have the pictures later in the week. Or at least by the end of the weekend....

Re: In tank fuel pump with nipples?

Here are some pics:

Not sure why I can't figure out how to post pics. I've done it about a zillion times. I thought it was Mozilla giving me an issue. But I can't post pics in IE either. UGH.

Re: In tank fuel pump with nipples?

Thanks Leve for posting the pic. I have three or four more pics at home that I wanted to post. But no matter how I tried, the computer wouldn't post it for me. Are you using the "image" button down below? It wouldn't do a THING for me. I tried using [] with the address in between like I used to do. But that wouldn't work either.

Can you give me a clue? Is it me? My computer?

Re: In tank fuel pump with nipples?

How'd you get the wires to come out of the tank? Did you just drill some holes and then reseal them? If so with what? I wanted to do this with my 15 gal. steel tank, but couln't figure out a good way of feeding in the wires.
