L body fuel system upgrade

[BadAssPerformance]

That's a tad low... and maybe would be better further back?

I dont think the pump has to be as low as the sump but even with the middle of the tank should be ok? Mounted close to the pickup would be key so if it does suck air, it would suck less.

To move it farther back, I could change to one of these:



But that's a pretty sharp 90...

Or get another bung to weld into the side of the sump for the feed?

Ok, took a step back since I wasn't happy with any of the fuel pump mounting options with the sump. So, I'll get the -8 feed and -6 return lines run into the stock hanger and run a single Walbro 255 intank pump for the time being. Got a couple bulkhead fittings installed tonight while I'm waiting for the pump and fuel rail to show up.





I'll probably braze/solder brass plugs into the stock nipples to seal them off flush with the cap. For the intank side of the -8 bulkhead, I'm figuring on using the -8 nipple hose end shown and run rubber fuel line from the pump to this nipple. This way with the bulkhead fittings all the lines on the car side can remain when I get to the point of needing more fuel and can do a dual walbro set-up, or single larger submersible.

And Cordes won't have to worry about me smashing up the sump on a speed bump!

I feel better already!

How much power are you looking to produce? Needing more than a Walbro 255 is some serious action.

[BadAssPerformance]

That will work

That was my question exactly

[BadAssPerformance]

He has an identical turbo to what is on my car

[Skibbe]

That will work

Getting expensive though... damn Unibit for drilling the holes was $34!

[BadAssPerformance]

Dont you work in Arlington Hts? HARBOR FREIGHT!

Next town over! Forgot to try there on the way home, was too busy trying to find a roll over valve... Oh well, this one should last through more than one project at least.

[BadAssPerformance]

Rollover valve? crap....

By unibit you mean step drills, right? I think the set of 3 I got was $10 ...well, if you count the other $100 worth of crap I got on the same trip, maybe not! Hard to get out of that place cheaply

That crappy plastic thing on top of the gastank that hooks into a vacuum line that's supposed to go to the charcoal canister? plastic was brittle and the nipple broke off while I was trying to extract it from the old tank.

And yeah, those step bits that work oh so nice for sheet metal.

[BadAssPerformance]

I hate 20yo brittle plastic

[iTurbo]

Looks great!

I sorta did the same thing on my Spirit R/T. I cut and drilled out the old tubes for supply and return and replaced with 3/8" steel tube from Summit brazed in and used AN-to-tube adapters to hook up the ss AN hose. Using a Walbro 255 ltr/hr in-tank pump as well.

Ugh. Ordered fuel rail and pump from TU.com last Tuesday and still don't have them. Ordered from Summit twice, once Sunday and got it Tuesday, and once Wednesday morning and got shipment today! I realize TU doesn't ship quite as much as Summit, but seriously...

Hi Mike,

Your parts are are already enroute. We upgraded the shipping to get them to you sooner. Our fab shop was finishing up the rails when your ordered. We appreciate your patience.

[Skibbe]

It's OK Chris, and thanks for the upgrade on the shipping. You're still about 2 years ahead of FWDP!

Got the fuel rail and pump today. Cleaned the flash out of the injector holes on the rail and got it bolted in place... then went to screw in the 3/8" NPT to -8 AN fittings to the ends... TOO BIG.

Doh.

I think the next size down is 1/4" NPT, but that seems damn small, and strange since the fittings TU lists online are 3/8" to -6... I was expecting a -6 (3/8") rail and knew the -8 feed would be larger than the internal dia of the rail, but didn't think it was choked down to 1/4"...

Oh well, Summit should get the fittings to me by Friday so I can at least get it running for the car show this weekend. Then maybe it's time to do my own -8 rail from Ross Machine extrusions.

That's a real bummer. My TU rail was 3/8ths NPT for what that's worth. Is it really 1/4" NPT? That is really small.

[Skibbe]

Maybe it was machined wrong, but mine is definitely 1/4" NPT... I pulled out my taps to check.

[BadAssPerformance]

I have a few fittings in the shop... might have what you are looking for?

Which car show?
