Alrighty so today was slow at work so i spent all day fabbing up my dual walbro mount. I took some pics for the main part...and ill get some extra pics tomorrow probably but for starters we'll show what was probably the most challenging part.



Basically I'm running dual walbros with (2) -8 feeds and (1) -6 Return all going from the tank to the rails. Obviously the challenge here is getting the fittings onto the fuel tank cover plate/fuel pump mount.



That is what we'll start with here as I took almost all of my pics of that part lol, the rest is somewhat self-explanatory if you look at the pics.



Only downfall here...it does require welding so that might eliminate some of you guys, but for those who really need it for the big power i figure you already need things welded anyway just add it to the list.



Tools/Parts:



(2) Walbro 255lph

(2) -8AN 90 Degree Hose Ends (i used earl's swivel seals)

(1) -6AN 90 Degree Hose End (i used earl's swivel seals)

(2) -8AN Straight Bulkhead Fittings

(2) -8AN Bulkhead Nuts

(1) -6AN Straight Bulkhead Fitting

(1) -6AN Bulkhead Nut

Some Metal Plate

(2) Hose clamps i think they were 24f or something

Welder

Air Grinder or Dremel

Wire Wheel (not necessary, but helps)





Onto the steps, unfortunately I have no pics of how it looks stock...anyone who does can post it but heres what we start with:







1) Alright so "what am i looking at" well this is the stock tank cover except i bent back the tabs holding the elctrical plug in (be careful not to break the connector, its pretty strong tho) and removed it. Then I cut off the "mount arm" that the pump mounts onto. You can make out where i scribed the plate around those two studs, that is the amount of room the fuel level sender takes up, aka do NOT cut into that area. Another thing to take into account, there is a gasket between the plate and the tank so use that gasket as an indicator for how far you can grind, i lef tit some room so it doesnt flop into the tank when i tighten it. You will use ALL this space, believe me (at least for my size line, -6 would be pretty easy.



"Why" did i have to cut it out and not reuse the stock locations? tried that, the placement of the stock lines makes it pretty hard to fit 2 -8's and a -6 on there, at least i found it damn near impossible so thats how i got to this point, and believe me I TRIED to make it work without doing this.







2) Here's the other side all cleaned up, to give you an idea of the space you're working with.







3) Here's the "Adapter Plate" I made. This isn't all that hard Basically i traced the hole onto a piece of paper, then i took a 22mm socket (the total size of a -8AN nut (taking into account the corners)) and a 12mm washer (the size of a -6AN nut (again taking into account the corners)). I laid them out and tried to fit the 22mm sockets and one 12mm washer into the tracing, the way i did it was the ONLY way i could find to make it work so i traced it, drilled it and then dremeled it out, dont dremel the size of the 22mm socket or 12mm washer tho, as the shaft of the bulkhead fitting is substantially smaller obviously.



Once i had it laid out and the holes drilled then i could focus on making it fit the plate. The easiest way I found was to use my air grinded and grind the U shape i'd need to fit it snugly around the connector holder, which also helped hold it down. once that was cut i slid it onto the plate, checked underneath and made sure everything still cleared.



Once i was sure of that it was just grinding it away a little at a time until it fit perfectly around the bolt holes.

4) Here's the plate just loosely mounted on the top to show how the cutaways line up with the bolt holes and slides around the connector's neck piece. You want to give yourself room to weld onto enough of a "meaty" surface.











5) The plate is still loosely connected here, this is a test fit of how the connector's go in to make sure they fully fit when turning the nuts to tighten them etc etc. Everything lined up good so it's onto permanent mounting!







6) Here's how my weld came out, pretty good. be SURE not to mess up around the holes for the bolts, you can grind it away but thats extra work, i think i left myself enough room if not ill have to go back and touch it up with the air grinder. You can see i also put the connectors in to double check clearance again and I finally slipped the connector in, had to position it differently then stock so it clears the 90 degree hose end fittings (remember this, that connector sucks to remove again)







7) Here's a view from the bottom, try and make sure when you weld it you keep that plate on there securely so it stays pretty flush with the mount, mines completely flat against the top, not necessary i guess, but i like it lol. Now you can really see how cramped it is for those big fittings.







8) And here's why you need to make sure that connector fits with the hose ends, they're MASSIVE, lol. but yea pretty straightforward pic.









9) and now fast forward and bam all done lol. I'll take it apart again tomorrow and get more pics of the steps I skipped but basically you just have to grind down some of the mount arm and weld it into the only open space you have on the custom plate. You want to try to keep it as centered as possible, mines a little off from stock but whatever. What I did which is, again, over the top is ground down the bottom of the mount arm to a flat surface, made a rectangle piece of metal and welded that to the arm. Then i cut a slit in the middle so my two hose clamps could slide through it and then around it and the pumps, holding them securely in place, I was on such a roll by this point i stopped taking pics LOL.



Enjoy, more pics coming soon, and if anyone has pics of the stock setup thatd be nice.

oh and my stock level sender fits/works perfectly



and i forgot to mention, ill probably need barbed fittings for the bulkhead fittings so i can slip the rubber hose from the pump onto them as i never realized how big -8's were until i removed them from the package and saw them next to the rubber fuel line on the pump lol.

Ok, you and I seriously need to have our heads checked... take a look at the family tree or something... that setup is VERY similar to the one I was going to run in my FC, lol... guess I'll come up w/ something new instead :P



Looks good though man...

teknics

LOL, all of that was sort of a headrush, i just started knowing i needed two tanks in there and had to fit them on the stock mount, no research or anything. jwteknix was there watching giving his advice every now and then. For the most part tho it was just attacking it and reaching the goal lol.



I figured not many people would go this all out so im not sure how helpful it is to most people on here, especially since welding is involved. But its a nice/important part of my buildup so i figured id post it

Intriguing!



Nice work!

jwteknix

yeah, kevin put alot of work into this thing, it is damn near 100% custom. i was soo surprised about how well everything turned out, b/c the first day he had runn in to a couple problems then i spoke to him later that night and he had a completely different game plan witch as you see above came out awsome i now know that when i eventually get around to doing this with all -6 an's how to do it. i cant wait to see the rest of his **** that he will have to fab up

teknics

this thing is still pretty.

jwteknix

yes kevin u did a good job did u do any thing else today?

teknics

hmmm no, ordered the fittings for inside that the hose connects to....once i have those im gonna plumb the fuel system me thinks. should be easy and quick.
