Watching Horsepower TV at the end of the show they hawk whatever pays the bills. Today they showed Edelbrock E-Street EFI. Joe Elmore says - "…if you are worried about adequate fuel delivery from your low-pressure pump they've got you covered with this universal sump fuel kit it's a self-contained tank high pressure pump and regulator…" no return lines required.
I suspect or goes inline with the existing pump but I couldn't tell from the 2 minute blurb.
I thought it was interesting.

I also saw that and found it an interesting possibility due to the simplicity of the system. Though I am from the carburetor age, I do appreciate the benefits of modern EFI systems.
I wonder how it would work on our rather unique intake manifolds? Has anyone actually installed one rather than the common Howell FI conversion?

I've seen this and other shows promoting that EFI.
The pump was an inline EFP with no return line needed; making it a much easier to install than others on the market.
Many pluses with a system like this bolt on EFI. (I know I'll miss a few)
1) Easy install
2) Easy starts (no matter how long the RV has sat)
3) Automatically adjust to different altitudes (great for when traveling and staying in areas that your carb was not set up for.)
4) May even help, if just a little, with MPG (depends on how one uses it.) Grin
5) Another Anit-theft device (if one adds in a hidden switch to turn on and off the EFP)
5b) RVS can sit more than a car that is used almost every day. Having a cut off switch for your EFP on your RV is a good thing for #5 above and a great way to pre-prime an engine that sat for a long time - before one starts it. Turn EFP off and crank the starter until oil presure comes up. Then turn on EFP and start the engine.
6) No float on an EFI to go bad and/or flood an engine
7) No choke worries. As a choke can stick closed or not work correctly at times.
Now I know that some of thses issues due not happen often nor to everyone. But they can happen with carburators.

I have an older car that I installed a similar system on (MSD Atomic Fuel
Injection) and it worked perfect the first time I started the car. Very
simple to install, no eng compartment clutter, low profile and best of all,
instant starting. If there is a drawback it would be the noisy ele fuel
pump. On a GMC this would be unnoticeable. Miguel Mendez (MGM GMC) has
installed quite a few of these and has more than once expressed his
satisfaction with the. A bit pricey but that's what you get for state of
the art TBI technology and ease of installation.

Larry,
I am following Steve Southwood's plan of using a low pressure pumps out of a 1969 Rivera in each of the GMC tanks through Poly
Armour to a surge tank which will supply fuel to the mechanical pump for the carb. The electric fuel pumps will supply fuel to the
bottom of the surge tank and there will be a line at the top of the tank that will connect to the 1/2" vent line on the fuel fill
system that will return the fuel to the tanks.
I am doing it this way because in my opinion it's the easiest way to be able to handle a carb and at a later date an EFI system
should I so desire. All I would have to do is replace the mechanical fuel pump with the appropriate pump for whatever EFI system I
install.
Here's a link to the tank I bought off eBay:
http://www.ebay.com.au/itm/Aluminium-fuel-surge-tank-kit-2L-polished-AN6-fittings-and-5-m-braided-line-/151101065678?pt=AU_Car_Parts
_Accessories&hash=item232e5349ce#ht_2592wt_966
I bought two tanks (one for Double Trouble and one for The Blue Streak) for $80.00 shipped to a mate that welded brackets on it so
it could be mounted on the GMC firewall.

Larry,
I looked at that self-contained sump, high pressure pump and regulator and am considering it for my EFI system. I guy that I know
at "The Carb Shop" in St Paul had one on the shelf and let me take it apart to look inside. It has Two...count em...two floats in
it that are similiar in nature to the Float system in a typical Q-jet. You use a low pressure pump to get fuel to the sump through
the float system and a High pressure pump in the tank with regulator to supply fuel to the EFI. A nice system in my estimation but
pricy at over $500. There are two kits they offer, one for a 49lb system and another for a 60lb system...both non adjustable and
probably useable as is for a port injection system where the higher pressures are needed. Here is the URL to look at it. About half
way down the page.

Having had both types I would definitely prefer a return system. While more complcated plumbing wise it seems to be more efficiant. Less problems with fuel heating and if you have some water in the fuel, a return system will sputter a bit and keep running whereas a returnless might stall out. the bypass regulaters seem to have less problems in my experiance, both with carbs and with EFI.
Jim B made some good points about what happens if your EFI breaks down out in BFE. You always have to have a 'Go to Hell' plan.
I have an older aftermarket EFI [Air sensors] that I used on my trans am that I plan to use. It is a low psi MAF throttle body type. I also will carry the Q jet and the parts to convert it back in a hurry if it fails. Easy to do with a bypass type regulator and the EFI pump.
Originally on the Trans AM I tried to run the mechanical pump feeding into the higher PSI EFI pump as a booster. Had problems with vapor lock downstream from the tank. Ended up running the walbo pump in the rear, but outside the tank for easier access.
Converting to a return stye reg solved a fuel delivery problem in my twin Turbo Corvette.

Speaking of EFI and electric fuel pumps, this upcoming spring I will be finally dropping my fuel tanks. I am contemplating installing in-tank fuel pumps, specifically the one JimKs sells. I eventually plan on installing EFI so I am thinking of installing the high pressure fuel pumps and of course a fuel pressure regulator to bring the fuel pressure down to carburetor friendly pressure. I will have to install a return line for the regulator but will need one anyway for the EFI.
Any flaws to my idea? See below the FPR I have in mind.

I don't see any flaws. You are front loading the $$'s, but it pretty much comes out the same. I'd look into a good quality pressure regulator. I understand they aren't cheap. I like the idea of 2 fuel pumps, but I'd be inclined to mount them externally as close to the tanks as practical. It just makes it easier to service, but I haven't thought it through completely. There may be benefits to having the pump submerged in fuel.

Always good to have a redundancy.
There is an advantage both in efficiancy and longevity to tank mounted pumps. Most electric pumps push much better than they pull, plus they stay cooler submerged in fuel.
Tank mounted pump is also quiet
Walbro pumps work well, are reliable long term and are pretty inexpensive.
Downside: IF one goes Tango Uniform, you will need to drop the tank onless you have access hatches.

Putting two pumps into the fuel tanks actually gives you redundancy. If one pump fails you can still get 3/4 of your 50 gallons out with the other pump. If you want to get at the other 1/4 before you replace the pump you can always hook an exterior pump in series with the pickup from the tank with the bad pump. You can pull fuel through the bad pump. I still carry one exterior pump with me just in case.
But, so far mine have been in for over 4 years now and are still going strong.

Good Idea. One word of caution on that: If its a Walbro pump and it jams up with a rust flake or something, It won't pull through. I found that out the hard way.
Which brings up another point. Make sure your pickups have large surface area screens or filter socks and are mounted at the low point. I'm told you can reverse the polarity of the pumps and backflush them periodicly but have never tried it.
Also: Walbros do not like being submurged in fuel with a lot of water in it

That is why one need to use an filter before the pump.

If you are using a high pressure system it seems like using a hp pump just after the change over switch and installing a Corvette fuel filter/regulator would eliminate needing most of the return line. The Corvette filter/regulator has a third line that returns to the tank and can be had for $45 or so. It's worked well in Corvettes since 1997.

That's how I plumbed the 48 Chevy with the 1986 Corvette engine.
Works just fine.
