I know this has been asked before, but with few, if any, replies. I am trying to configure the hard fuel lines for a mini-ram, but can't figure out where the AFPR goes. I need a pic of the rear end, where the hard lines screw into the fuel rails, and where the AFPR locates in relationship to the fuel rails and hard lines. I have them snaked up in to where I think they go, but something is wrong, evidently. Help please!!

I have some "in my pics". if that helps.

 

First of all, very nice looking engine! They don't help much because they are either from the side, or front. I can't tell where the hardlines connect to, and it appears your AFPR is different than mine. Also, where is it plumbed to? That is one of the things I can't figure out. Some shots from the rearmost possible, on each side may clear it up for me. If anyone can shed some light on this, please do.

The return fuel line connects to the pass. side rear bottom of the fuel rail, the other connects directly to the afpr. If needed I can snap off a couple shots tommorrow and PM them to you...let me know

 

Please do. I just can't figure it out, mine seems different than yours. Thanks a lot.

Rich

P.S. Tha pass side hard line connects to the back of the fuel rail to a 45* fitting comimg off the bottom, and there is another threaded hole on the front end of the pass side, in the same place with a 45* fitting screwed into it (where the original setup feed line went). The driver's side line connects to a 90* fitting coming off the bottom also, and there is another threaded hole pointing directly towards the pass side. I just can't see how the AFPR reg can be put there. (Looks like it would be in the way of the distributor.) Plus there is a threaded vacuum hole in the body behind the fuel line, that must need to be plugged. I will take some pics tomorrow also, and see if I can post them. Guess I should have just bought braided lines. Nothing is easy on these TPI engines.

 

 

Yes it does help, immensely. It shows that I spent $60 on the hard lines for nothing. My crossover tube is different, in that it goes from one side to the other in a "U"-shaped steel tube. It connects the same on the pass side (with the 45*angle), but on the drivers side, it is bent to attach where your AFPR is. And where your crossover tube is, the driver's side is threaded and another tube, also "U"-shaped screwed into there with a 90* elbow and runs to the AFPR, where there is a fitting (which I assume is the supply line), putting my regulator on the pass side. Then on the front of the pass side is another fitting identical to the one on it's opposite end (meaning also w/a 45* fitting),
which I assume then is where the return line would connect to.
So, I don't know if mine is older than yours, or newer, but I can't see how to plumb the AFPR, unless I had a "T"-fitting where your regulator is, and cap off the other hole.
Nah, that would't work because then there is no cross-over tube, so only the driver's side would be regulated. The pass side would be victum of however much pressure the pump was supplying to it.
By looking at yours I can see that all I need is the same style pass side fuel rail (mine is not as long as the other, where the cross-over tube is), then I would also need the same type regulator as yours also.
So what would be cheaper, braided lines and leave it plumbed w/the regulator on the pass side (which will make getting to the dist. hold down bolt a real PITA), or get another pass side rail, and different AFPR? Why me, I ask once again?
Am I correct in assuming the line going to the AFPR is the supply line, and the one going to the pass side ftg. is the return? If so, I may be able to pull this off somehow, if I can find a "T"-ftg to replace the 90 on the driver's side, and another where the hard line connects to the rear of the pass side.
ANYBODY WANT TO BUY MY NICE, SHINY HARD LINES? $50

P.S. 89onlyZ51. Thanks for the photo. It says it all, and at least clears up my options, instead of scratching my head wondering why nothing fits right. I have a pic of the pass side fuel rail like mine, on another car in "my photos", but it will NOT copy and paste. Any help putting it on here would be much better than my description.
Not to forget you, mseven, thanks for your help too.

 

your PM box is full

 

I don't mean to hijack your thread here, but I'm about to order up a fuel rail kit from TPiS for a used Mini-Ram I bought this past summer. Based on what you've stated, should I not order the fuel rail kit for the Corvette and instead just order up the "basic" fuel rail kit (for $60 less)?

Thanks

 

the kit should include the AN fittings to make it work with the existing lines. I originally bought their kit and it all went together well. It is my understanding they don't sell the hard lines anymore, only the braided stainless (aeroquip style).

 

Corvette Kid,
The problem I am having is that I have the 1st generation manifold, which used a different setup from fuel rail to fuel rail. Also, the AFPR is fixed on the gen 2 driver's side fuel rail. My isn't. It has a larger "u"-shaped line running from the driver's side to pass side, then another line from a fitting on the bottom of the driver's side rail to the AFPR. I am still trying to figure out, w/different ftgs, if I can use the hard lines I bought. Twisted offered to refund my money, but he and I and mseven (not sure if that name is correct), are working on it. Good luck with yours.

Rich K

 

Thanks Rich!

The Mini-Ram I bought this past summer was only a couple of months old at the time (according to the seller) so it may be one of the new Mini-Ram IIs (I guess?). But as I said, it didn't come with fuel rails so I have to order up a new set from TPiS. I'll be doing that within the next few weeks (just waiting to pay down a few bills before I pull the trigger). I just wanted to know if I should spend the extra $60 to get the Corvette-specific kit or get the generic kit. Personally, I'd like to run the hard lines if I can - they give it more of a "factory installed" look. But I'll cross that bridge when I get to it.

Thanks again, and good luck with the install.

 

You're welcome. Good luck w/your install. I am not so lucky and it appears I may be stuck using braided lines. Not enough research before I bought it. Oh well, we learn by our mistakes.
