Is there some website that can help me figure out what fittings I will need for my fuel system? If not someone needs to make one! I figured the hose and fitting manufactures would have one or at least offer the help if you gave them all your sizes! How in the world am I suppose to know, all the fittings that they have available? They might have one fitting that would do the same job as three hidden some where in their massive catalogs!

Tank (2) 1/2"npt
Filter (2) #8 AN
Pump (2) 3/4x16
Regulator (2) #8 & (3) 3/8"npt

I know I will need (1) 3/4x16 plug (2) #8 AN plugs (1) 3/8"NPT plug.

The tricky part is that they say run -10 lines all the way to the regulator and back for the by-pass! I guess I will have to buy (1) 1/2"/-10, (2) -8/-10. (2) 3/4-16/-10 & (1) -8/-10 adapters. (male / male adapters)

I'm thinking of running the nylon braided hose instead of the SS braided hose. Any opinions?

One more question.

Would you run -8 or -6 dual feed lines to the carb or one single -8 and use one of those pre-made fuel line fitting setups?

All this is feeding a single carb, 460 with maybe 325hp that is going to use a 150-175 shot of nitrous.

I do plan next year (or years to come) to build an larger engine that produces 750 hp total.

I care about you Jones. :lol: I went to http://www.magnafuel.com for alot of ideas on my system. I bought a Magnafuel Pro Star 500 pump and Magnafuel big port regulator. I'm coming out of my fuel cell with a -12 an bulkhead and line to feed the pump, -10 out of the pump to the regulator up front, -08 out of the regulator with two seperate -08 lines to the fuel bowls. The return is directly off the Magnafuel pump, so I don't need a long return line (one of the great things I liked about this pump). The return off the pump is -08 to the fuel cell, and I picked up an -08 vent/roller valve for the fuel cell. I bought everything to put it in, but I can't buy time. I've been working almost everyday since before Christmas, but I'm off from Feb 10-13 to get this and my new front end in. I have to get ready for April down in Kentucky. I'll post pics when I finally get this stuff in. 8) My system is total overkill, but I bought the fuel stuff for an awesome price on ebay, and everything is brand new except the pump with only a small amount of time. It looks like new! 8)

forgot to add, I'm using all braided line. I was going to run that blue coated rubber line, with the press on fittings, but wanted the tougher braided line since I drive so many street miles. :wink:

Will two -8 lines be large enough to feed my pump? I was going to use both 1/2"outlets on the sump. Then the two -8 outlets on the filter into maybe a y-block feeding into the 3/4-16 inlet on the pump.

Another thing is I am debating on using 5/8 aluminum tube or -10 to the regulator and back to the tank.

I know this also might be over kill but I don't want to do it again because it might be too small. I am using the Mallory 250 pump, Mallory 500 filter and a 4 port Mallory by-pass regulator.

Do you know anyone else that makes a weld on sump with larger outlets than 1/2"? (I was looking at the Competition Engineering sump)

Here's the setup I have on my Bronco.I used the stock tank but I had a sump welded in it. The pump is an Aeromotive,it's the Street strip pump(part# AEI-11203),not the H/O pump.This pump has to have an external regulator because it will flow 18psi pf fuel.The fuel system is all Aeroquip,I have a -10 (5/8") line going from the tank to the pump with a 100 micron filter before the pump. I have a -8 (1/2") line going from the pump to the rugulator, with a 10 micron filter after the pump. At the regulator I'm running a -8 return line back to the tank, and a -6 (3/8") line going to the carb. I could of used a pump that was already internally regulated but I wanted a return style instead.The system I have will support 700 horse no problem,it's a bit over kill but when I add nitrous the fuel system is already set up for it.

Yup I'm using a factory style rear 19 gallon tank also. I am going to have the sump welded in hopefully with-in the next two weeks. I don't know whaere I am going to have the return welded in at.

I had my return going into the port next to the supply for the pump. I was told by a few people this was wrong cause the returned fuel has all the other weight of the fuel that's in the. So I recently put a fitting at the top of my tank.

Wooo,, is that the 30 gallon tank? I guess I will just mount it some where so it's not returning near the pick-ups. Just have to see what is the easiest to get to without having to drop the tank.

That looks to be that same type of sump I am going to use. I am going to get the one with the 1/2" bung's and use both as a pick-up.

It's a 25 gallon tank. Remember your going to have to seal the sump after you get it welded in. The sump is just mild steel, I didn't do this to mine and the sump rusted and cost me a fuel pump and other grief. Here's the tank installed.

Back 11-12 years ago I used some white tank sealant in a gas tank that had some small rust spots. If I can find that stuff again I plan on using that. I remember it said I had to find "white or clear" gasoline and rinse the tank out with it. Then poured some in, taped the hole and began sloshing it around. Let it sit out in the sun for so long and re-installed the tank. In side was all nice and white.

What did you use to seal the tank with?

I got rearended before in my Bronco and the car went under a little bit. I turned it around to better protect all my fuel system,pump and what not. I never had any problem's with it starving for fuel.

Another question.

How should I attach the fuel lines along the frame rail?

Should I drill and rivet, or can I use some self tapping screws?

Is there another way I am not thinking of?


I am going to run -10 from pump to regulator and -10 back from regulator to tank.
I have yet to try to drill into this 1979 frame. It might be as soft as butter or it's hard as a file.
