I added additional strapping because the kit they offer for this unit is meant to hold it in place, not really as "hangars". I think it'll take a few weeks before I can post install of Walbro and fab of chase, etc..

This: http://www.summitracing.com/parts/rci-2162ab Fit pretty well - maximum fuel capacity in stock location minus spare tire well with room for exhaust

Yes; stock external through same filler door. Going to loose interior space because the new filler is above original trunk area floor. This is where the Sheetmetal work is taking place.

Thanks Tim; we removed the tank anticipating locating I believe a '76 tank, the earliest compatible model with a baffle. We had the turbo motor, and we're replacing all fuel lines, etc.. A fuel cell became an easier to acquire option. Also, the $700+ cell-pump combos scared me off... We aren't going to run E85. I found a neck and breather combo which fits perfectly. Also a filler inlet at a 45 degree angle for the top of the cell. I will be doing some Sheetmetal fab around all where the spare used to sit. I'll post pics when I'm doing it.

Tim and New Zed: only item I'm still wondering about: the aluminum cell doesnt have an internal rubber bladder. I mounted it well with a lot of support with no potential for abrasive vibration, and it's in exactly the same spot as stock... Is there a reason to worry about this in a daily driver?

Thank you. This Walbro unit comes with a tray to compensate for the issue of baffles and efi swaps

The fuel cell not being tapped for an in-tank pump was okay with me until i read about overheating fuel, cavitation etc. (we arent running a super high performance motor -- pretty much a stock set up) Reading about how to overcome these potential problems brought me to two options: 1) the external set up; low pressure pump, swirl/surge tank, high pressure pump, reulator, return in minimum 3/8 inch line Or 2) drill out fuel cell for Walbro 255 with tray in-tank pump, filter and regulate externally continuing in 3/8 inch supply to inlet on rail, return to cell in 3/8 inch If the second schematic sounds ideal, i want to do it (actually, i ordered the Walbro last night in anticipation). Looking for the easiest to maintain and troubleshoot system. I already plumbed the new rigid 3/8 inch lines through the tunnel and hung the cell - this pump and return question is really a "What is best to do now?" Query.

This is quite the simple solution, but still requires a whole lot of joints and two pumps (potential for leakage, additional pump...) I think I want to just tap my rci fuel cell and install this: Walbro 255 Then regulate pressure, filter, hook up to my new 3/8 feed and come back in my new 3/8 return. That sound best to you New Zed?

New Zed: I guess I couldn't find what I was looking for until you told me to search in this sub-category... That was good reading! I like the BCBroncos solution; small little oil-filter-type swirl tank. But I also like the drilling out/tapping my aluminum fuel cell for an in tank pump -- nobody posted anything after in that 2011 thread. I'll go back and save some images to post now (BCBroncos and the other in-tank)

Blow hards... Pros at selling wolf tickets... wannabe men who spend all their money and time on themselves barking loud about a father-son project? Let me guess Porchephile, you wear designer jeans and take selfies in front of your 924, and are considering "A Touch of Grey" so you'll be taken more seriously?

Alright - thanks for the lead New Zed; I'm not wanting to reinvent what I've done so far. It's just the boiling of fuel / cavitation problems I read about troubled me. The submersible/in-tank pump seemed to solve that. I'll read about the Surge Tank

We're putting an '83 Turbo into our '72. We read about needing a later model tank to swap in, with a baffle, etc., and knew our fuel lines were insufficient -- bottom line, stock wouldn't work so we got it out of the way.

I think I screwed up; didn't like the cells with pump prices - damn! Pricey; thought I could purchase pump and filter and save @ $400... But the whole cavitation and overheating issue is something I was unaware of. So, now I toss the fuel cell and start searching for an all-in-one unit. Besides, I learned the single wall aluminum cell I was intending to use wasn't sufficient for the application; mounted where stock tank was, exposed, should have a rubber bladder for safety. Thanks for the feedback. Will post replacement system here when I find one. Submersible in-tank pump is the only way to go for these turbo conversions, is what I'm thinking.

Oh? The "it's dangerous, stupid and hard" I guess was the sophisticated and solicited input I was looking for, but my tunnel vision had me ignore it, right? Thanks for pointing that out, big guy.

So I'm wondering what performance issues I may be dealing with, with this smaller booster.... All new SS lines, rebuilt front and rear to stock (disc front, rear drum) and new slave from Black Dragon Spacer isn't shown between slave and master, but it all lines up and seems to fit well.

Here is the part info (looked pretty much untouched when bought; said not to have been run since the 80s):

Uhh, 6psi? Fuel injection turbo...

Makes sense. Hopefully this fuel cell from Jegs will allow this option easily.... Thanks for the reply. 1) Submersible/in tank pump, 2) filter 3) regulator set at 40psi 4) connect to rail inlet 5) return from rail to tank Any other items in between I'm not factoring in? Check valves anywhere?

I just pm'ed Tony D on this -- man, there are a few threads talking about the heat and vapor causing cavitation, etc., especially when fuel level is low. These questions have me really questioning my set up; no more stock tank, fuel cell, new feed and return rigid 3/8 inch lines, a rollover vent... The pressure I'll need is 40psi constant for the turbo L28? So the inline pump I want has to deliver enough volume and pressure, and then needs to be regulated at 40... How to plumb this? Where is the regulator? Do I need a charcoal cannister? Cavitation issues worry me, pressure loss worries me, I'm a regular cluster__ of questions now!

Ohh shit; I don't know my arse from an inlet... Tony D.: I've got another thread on this fuel pump and regulator issue and I'm not getting feedback. We have an '83 Turbo going in our '72 and we just hung the fuel cell which is being used as our primary tank. My question(s) is: I want an in-line pump recommendation and now I want to know where I put a regulator and regulate to what pressure? Can you help? I've got new 3/8 rigid fuel line to engine compartment and 8an tubing at the cell where if like to plumb the pump, filters and regulator. Can you help me clear up pressures and fixture locations? We'll be fabricating a chase/cover for these items around new filler neck, breather, and Fatts Rollover tubing - maybe I can squeeze the pump and regulated under it as well.

Thank you for the reply. You've got a turbo? I'm taking pictures on my ipad and new iPhone 6 Plus -- doesn't work with Apple?

No substance in your response Xnke. Have to share some mechanical and engineering feedback, the substance, before you start lecturing. We "live a little" out here, and drive our classics... Like the fast women too.

I'm looking for an easy to find (O'Reilly?) fuel pump recommendation. Just one that works for the turbo conversion. Anyone?

Kevin.pk Thanks for that thread from Raayaap (?) - I asked: "I seem to be doing the same; getting rid of the distribution brake lite and pressure balancing valve. I'm reinstalling a manual adjustment balancing valve (son wants to drift when he wants ...). The rest of the brake system is stock. Can you tell me what problems you ran into? If any? Thanks." Any of you have thoughts on this? The last time I asked this question, about a year ago, it was on a different forum and what a pain! Three wanna-be lawyers telling me how reckless and stupid this idea was... So I guess I'm up for more abuse -- only Hybrid seems to attract a more knowledgeable crowd, or understanding of the youth's need to impress the chicks in the high school parking lot.

Yes; sort of stock... Front disc, rear drums. Then stock slave -- abandoning stock pressure balancing valve and switch/light and installing manual adjustment valve. All else stock. So thank you! I was getting frustrated. Any concerns or further queries -- always appreciated
