Berak, I'm not touching the stock filter or mount... that is until I change the filter . That is the point where the return from the cp3 and the "blowoff" valve (whatever it's called) from the injection manifold meet with a banjo fitting on the stock filter mount. I can't see too much after that from above, but when I get underneath I'm sure it just runs back to the tank. Someone correct me if I'm wrong.

 

On the 05, that is what happens. The return line from the CP3, the return line from the rail over flow valve and the return line from the back of the head all meet up there. I don't think you guys have to touch that either. But I am not sure.

If you are mounting the pump on the side of the engine, there should be two lines you have to concern yourselves with. One will be the suction line from the tank and the other will be the pressurized fuel line that goes to the side of the filter housing, near the firewall.

I *think* some of the other pump systems needed to tap into the return line because the regulator was at the pump.

If you are putting the regulator at the injection pump, you will tap into the return line (or create a bypass line) there. No need to tap into the return line at the fuel filter.

Let me know if I am wrong.

 

I see now you have a 2005, so I have problem (2003 model) you don't with my filter mounted pump. I would need to remove my pump and replace it with something to get the fuel line into the stock filter.

 

"I see now you have a 2005"
Yep.

"so I have problem (2003 model) you don't with my filter mounted pump."

OK. Yes, your pump is mounted on the engine by the filter. I've seen them.

"I would need to remove my pump and replace it with something to get the fuel line into the stock filter."

I am under the impression that the stock pump has an inlet and outlet fitting that a hose can be put on. And that fuel is fed into the stock fuel filter by a banjo bolt at the back of the filter assembly, near the firewall. Is this right ?

 

Sounds correct to me. Took a coffee break and got under the hood again. I really don't think I'm going to have the room for the 2micron filter in the engine compartment. The only place it seems logical is above the power steering reservoir and it'd be tight for all involved maintainance. It would also make it alot tougher to route all the lines and swagelok. I don't know.
Actually, I'm so busy doing 5 different projects at work, that I'm sure someone else here will finish one up before me. Maybe that'll give me more ideas...

 

I'll mount mine and post some pictures when its done.

 

I found another pump that might work... the pump from a Dodge gasser truck of the same year.

The Dodge gasser pump outputs 60 PSI to the fuel rail on the gas models, so it is decently stout.

$173. I have no idea if it will stand up to diesel fuel.

Gasoline part number (of several) 5104696ab

This is probably a gerotor pump with no built in pressure relief.

You would have to run a bypass and/or a pressure relief at the injection pump to use this.

 

I haven't even looked at it yet, but I read somewhere in one of these threads about a special o-ringed fitting directly from the injection pump into the filter. And I also read about a special fuel line to bypass this from Dodge and another one from FASS for their kit. So based on that I thought I would need a special adapter of some type. I guess I'll have to get a good a look at the filter and pump soon.

 

So this begs the question, why wouldn't Dodge use this in their retrofit kit if it is such a good pump? Why put another POS pump in the tank if you got this one in your parts bin?

 

I'll answer this in the "What is so great about the Walbro" thread.

 

I'm anxious for someone with an in tank retro fit to try mounting a Walbro/Bosch in the new in tank fuel pump assembly. If I had more money and time, I'd be installing one this weekend.

 

Edit: this is about ford's....

Slightly off topic, Going back a few years there was a lot of discussion about cackle on the ford 7.3 engines. many of the threads that went around and around on this topic discussed the ford quick connect couplers on the fuel lines and how they were letting air into the system. This was particularly troubling to the 7.3 as there was no where for the air to go except through the injectors.
People were modifying their fuel systems to remove those couplers. I bring this up for SD's benefit since he has a ford and the couplers in question. There was something else about the return line and the intake being in the same place with the return line also introducing air into the supply line.....

 

sea01cummer, what size inlet and outlet fittings are on your bosh pump, I hope they are larger than 10mmx1 like the walbro pump.please respond.

"I hope they are larger than 10mmx1"

What is wrong with the inlet and outlet on the Bosch pump ? 10mm = 3/8"ish. The Walbro is the same by the way. Fittings off one go on the other, IIRC.

 

I read about your 1/2" lines in the "What is so... FASS" thread.

You didn't need to enlarge your lines. And there isn't any need to resize the inlet/outlet. Trust me. Just plumb it up with what it has and you'll be happy. The Walbro has lots of pressure capability. The small lines/fittings won't slow it down.

I can't remember what we did for fittings. I think the pump came without them and we forgot to order them or something and either the Bosch fittings fit or NPT fittings fit. I'd have to crawl under my truck and check.

10mm is 0.390" ish. The OD on a 1/8" fitting is 0.405, but it is on a taper. 1mm pitch is 25.4 TPI. 1/8" NPT is 27 TPI.

I might sound unorthodox, but I think we used brass 1/8" NPT fittings and they worked fine.

I remember there was an issue, but I don't remember how we overcame it.

You might want to use a 1/8" x 3/8" nipple and then a 3/8m x 1/2" compression fitting.
