I'm in the home strecth now on my 6.0l turbo project. I ordered an in tank walbro pump but I believe I have a problem. The previous owner had already swapped a BBC when I got the car and he used an external FP. After further inspection I see that he also cut all four lines coming out of the sending unit and used hose clamps (pictures will show what I'm talking about).

My question is since these lines have been cut hose clamp won't handle the pressure of a fuel injection pump correct? Does this mean I will need to get a new unit or is there a way still use the in tank pump?

Also what is the white wire that has been cut in the 3rd picture and will I need it?

 

You could cut the tubes shorter at a clean spot, then either use compression fittings, or flare the tubes.

It really irritates me to see things like that done to our cars.

 

Find a new EFI sender, itll come with the wires and fuel lines. V6, TBI, TPI, doesnt matter. Just not a carb

Cut wire was fuel pump 12v

 

It irritates me too because I'm ready to hear this thing run.

 

So mine was a carb car? I will try to find the one that you suggest. You wouldn't happen to have a picture of one would you? I just want to see the difference to make sure I don't get the wrong one.

 

Your pick-up started as an EFI unit. That's what Pocket was saying, the cut wire was the 12v line for the in-tank pump.

 

Ok I see now. Thanks!

 

You might be able to fix this one up, but I think Pocket is right - getting a replacement that hasn't been hacked up may be your best route. The EFI pick-ups are easier to come by than the carb type pick-ups, so you should be okay there.

 

Can these be replaced without dropping the tank?

 

Personally, I'd drop the tank and get everything right. I assume your middle picture is the lines coming off of the tank. Those alone would be a bear to try to repair. With the tank out and new parts in hand, the job would be simple.

Of course I had my rear end out anyway when I did all this, so it's easy for me to say.

 

I figured you would say that after looking the 90 degree bend on the hard lines. I wonder if there is enough room (between the sending unit and the floor of the car) to drill the supply line out and replacing it with a bulk head fitting. From there put a -6 AN fitting and a 90 and go from there.

 

I'm also really thinking about those compression fitting as well. Do you have any more info on them also the pros & cons of using them?

I got brass union fittings from Ace Hardware. Slide the nut over a clean-cut, round tube, slide the ferrule (compression ring or sleeve) over the tube, put the union on the tube, slide the nut up and thread them together. Tighten, move to the mating tube on the other end and do the same thing. Simple, leak-tight, can be disconnected and remated in the future.

You'll need 3/8" for the fuel supply line, and I think 5/16" for the rest.

 

Got it. It's just like the fitting for the oil pressure gauge. Thanks!

 

Well, maybe the way my sending unit was damaged may be a better solution after all. Now I can remove it without dropping the tank.

 

Looks good.

 

I didn't look over the whole thing very carefully the first time. Are those wires going through one of the tubes?
