Hi,
I need to do the fuel return lines on my 89' idi this summer, they're original and have been leaking for years. Im wondering if there's a kit that stands out from the rest or better yet an FTE'r who sells them with quality parts. I'm aware of the r and d billet kit but it's a bit spendy for a truck that's averaged less than 700 miles a year since new.

I'm also looking to replace the mechanical lift pump with a facet. And was wondering if there's a kit that's got everything thing I need. I get 2-3 hours a week I could work on this thing and would like to avoid turning it into a 3 week project as I run out of time driving to and from the Irish parts counter. Second best would be if somebody could point me to a thread with a complete list of everything needed, so I don't need to exercise my lackluster planning skills. I've skimmed a few of them but my search skills aren't up to snuff and I haven't found what I need yet.

Thanks!
Joe

 

I did mine a year ago and it has worked great, no more leaks or diesel smell coming through the vents, I bought the generic package that was referenced in previous posts I had read, I'm junior grade and it wasn't a difficult job but probably 3 hours for me because I have a turbo in the middle of it,

You may consider changing the glow plugs and wires at the same time since you'll be there right on top of it,

 

Mine is a daily driver... 3/8 SAE hose from any parts house; injector grade on feed, screw clamps, and facet 40222 if you want electric. My tanks, senders, selector are all new and I sourced and installed them; zero customized fitting except for the Facet, and don't wire Facet to GPC use the fuse block

Pegasus Racing is the best Facet vendor


I don't have to plug in at 20F and start within 5 rotations if that counts

 

These are the type fuel line clamps you should use.

You should use a Hobbs switch when using an electric fuel pump.
You wire the pump through this switch.
It screws into one of the oil galleries as a safety in case you get into an accident.
If the engine dies, the oil pressure drops which cuts off the juice to the pump so
it doesn`t keep pumping fuel.

I've had great results with the Delphi kit. I replaced my lines because the plastic caps that go over the injectors were cracked and would seep fuel. The kit comes with lines, o rings, copper washers, hose clamps, and the plastic caps. Pretty much everything you and it's not too expensive. I put it in a few years ago and haven't had any issues.

Personally I wouldn't replace the mechanical pump with an electrical one. The very mechanical nature of these old IDI motors is one of their strong suits. So I wouldn't introduce any electrical variables to the system if I were you. But if it's going to provide a lot more benefits to what you use your truck for then go for it.

 

The Hobbs switch is a pretty good idea. Haven't seen that before. A little more effort up front, but probably worth it from a safety perspective.

Those clamps seem excessive though for a line with less than 12psi. I'll probably use them because they're nice, and I like nice. But if it wasn't for the vibration the connections will experience the hose on the barb would probably do it alone.

Thanks for the link. Unless I find an FTE'r or sponsor that's probably the route I'll go.

As far as the lift pump goes. I agree with the mechanical sentiment. But my biggest problem is that I don't drive the truck often. With 22k original miles I'm on my 4th lift pump, and I don't even know how many sets of batteries I've put through that thing. The mechanical pumps inability to prime without cranking puts so much strain on the starting system. I loved doing the fuel filter on my 7.3 super duty. Drain, replace, turn key to prime X3 and start. I dread changing this one. I almost added a racor prefilter with a hand pump a few years ago, but this just feels more elegant.
