I just bought a sard fpr for my 88 ttii ( the nipple one) and was wondering what fitting i need for it to put on the fuel rail. I searched for it and didn't get clear answer. i'm new to this and not sure on the fitting. If anyone can help that would be great. I looked up earl's fitting, but i have no clue which one would work.

 

Why did you buy the Sard FPR?
Is something wrong with your stock FPR?

well, i'm upgrading injectors, turbo, and putting in the pfc, and when i boost, my pressures not holding, so i went with sard. Bought it, but need the fitting to put in on the fuel rail. Don't know the size i need for it to fit, so thats where i'm at right now.

 

im guessing it uses NPT fittings (not sure what size). you could get an NPT to barb fitting to use the stock rails or you could be a baller and get a complete -AN / SS line setup which will run a couple hundred bucks.

 

The thread on the end of the fuel rail is a M12x1.25 fitting.

 

so do it need a - AN 6 - NPT 1/8? or do i need a -an 6 - m12x1.25? i'm sorry, never done anything like this before, so i know nothing about this. so if someone can tell me exactly what i need that would be great. i just want to make sure i get the right thing. Thanks. i think the sard uses an 6.

 

dropping fuel pressure is usually a sign that your fuel pump isn't flowing (provided that you have a good fuel filter), usually because it needs to be rewired.

 

does that mean that fpr is not the problem? How much psi can the stock fpr hold?

 

I had an fd pump and the stock one held fine, but after the walbro it couldn't keep up and I was seeing almost 60psi at idle! Thats when an adj reg comes in handy. So it does sound like maybe the fuel pump sock is partly clogged or pump ot getting all the voltage it needs.

 

i just change the fuel pump to the walbro, and its new so i really don't think thats the problem...

 

Same thing was happening to me. THe fuel sock on the pump is getting clogged.The way that new filter is on the bottom instead of the big stock square one creates problems with a dirty tank.

 

okay, checked all that, the pump is fine and the tank is clean. I drained it and didn't see anything. I bought a -6 to a m12x1.25. Will that fit? I should come by friday.

 

okay so i bought a m12x1.25 to -6 and its a little too big for my regulator, then i bought an adapter for that, and it doesn't fit. Can anyone let me know what exactly to get please before i waste more money. lol and i'm trying to stay away from barb fitting it,i want to buy the right adapter so i don't have to do all that.
