Ok, I started the upgrade on my fuel system this afternoon. I was just gonna fix the fuel gauge sending unit, but I was already in there, so...
I pulled the bed loose and jacked it up since I had no help to drop the tank. Worked great, till I had to run the fuel line. Maybe I should have went bigger, but, I ran 3/8 pickup to 3/8 line--into a napa pre=filter/ water seperator. Then on to a second pump I robbed off the bronco II....:lame:.
Sposed to be a 350 lph @70 psi pump. I know it will put out well over 100 psi , cause I broke the fuel pressure gauge on the little bronco messing with it. Ran it from that pump on to the stock pump. Temp. wiring till tomorrow on the new pump. Havent had a chance to try much since install.

Let me say this.---That stupid plastic nut that holds the pickup/ sending unit in the top of the tank is a &^^%^^^*&*766545576*&^%7 mofo to get back on a started!!! Took me at least an hour to get it back on. Where are most of you pulling power from to the pump? I dont want a rigged up looking bunch of junk, I'd like to not even see the wiring. Will be putting a gauge on tomorrow to see what its doing, hopefully its holding, and I can shim the regulator to somewhere around 65 psi. Got pics, but havent taken them off the camera yet. I didnt realize the stock lines were that small.

Forgot to mention, the reason I pulled the tank in the first place---fuel gauge quit, stuck on full. When I pulled the pickup out the sending unit float was stuck in between the tubes for the suction/ return lines..
Anyone ever seen that before. Works fine again now.

yea mine stuck in wierd places before it stuck down onece and up at the top once and i know what you mean about that damn ring on the top of the tank it is a mofo to get started and back on

I ran all new wiring direct from the battery, into a relay for each pump. Each relay is triggered by the factory wiring that used to run to the original pump.

I ran my pumps in parallel with each other, rather than in series. Running them in series, you can increase the pressure, but you do nothing to increase volume. At least thats the way I see it.

Running them in parallel seemed to work to, because I can hold 62psi all day long at wide open throttle. I used a 5/8" pick-up as well.

Heat gun works wonders for that ring. Or sit it out in the hot sun on asphalt while you work in the garage.

I've got much larger fuel lines if I can ever figure out what I want to do with this whole fuel system.

I ran a 5/8" pickup out of the tank, #10 feed line into a Dahl 150, #10 line into a y-block, 3/8" lines to feed each pump (parallel), and #6 line feeding each head and finally using a regulated return. I don't have a pressure gauge and am not making tons of hp but the system works for me. Here is a pic of the bracket for the fuel pumps:

I need to take some updated pics of the mods I've done within the past six months and update my webshots. Anyways, hope this helps.

We used to put that plastic ring in the heated parts washer and spin it on or if we were having too much trouble we would smack it with a rubber hammer to straighten it out broke a few that way tho. Parts washer was the easy way tho.Had to pull a bunch of tanks last year do to the awesome fuel we got last year. :lame:

Like two or three months ago it happened to me. I got another unit from wrecking yard and modded it. Dropped the tank to find the float stuck up. Put in the modded pickup unit. Now I have a spare sending unit/pick up sitting in the garage if anyone needs one, $50.

I was planning on taking the stock electric lines and use them to trigger a relay. That relay is fed from the battery or fuse block. Then feed the pumps off of the relay.


Dennis at ITP has some great advice on this. Put the ring in the sun and keep the tank in the shade. It worked great for me. It went back on easier than it came off.

Or you can do the boil trick. Boil a pot of water. Drop it in for a few minutes, then pull it out, walk to garage and screw it on. Heat works like a charm.

Thats what I ended up doing. Left the stock wiring to the stock pump , added a relay on the driver side. Hot wire from the feed wire going into the high amperage fuse block, and used the stock pump wire to turn the relay on and off. Works great so far. Still havent got a gauge on there to see what kinda pressure its got, but it def. feels better. Real neat. Cant even tell its on there. No extra noise, no gaudy looking wires hanging around under the hood.
