'71 B-Body EFI ?

rrTor-Red · Jul 15, 2019

Anyone done a conversion on a 71 B? I'm looking at the possibilities and want to learn from anyone who has done it. I don't think, least from the companies I contacted, no one is offering a in tank EFI pump set up(?). Currently have a 400 stroked in my car

Check Ricks Tanks, El Paso. I got a custom made by choice to increase capacity with a PMW in tank pump. The best. Fit and performance excellent. Not cheap.

Hi, I’m about to start my conversation on my 1973 charger tank myself. I did just a little surfing on the internet and found some images of other people cutting a hole and installing either the pump by itself or welding a recess in the tank they already have in their car. Yes, not a plug and play route but I am wanting to make my car look as much stock as possible. This way may not be for everyone but the way I’ve chosen. Tanks inc. has all of the item needed to accomplish the task at hand. They even have a video there as well to give you a look at a Version of a way it can be done.

Good luck,
Azmoparboy

Tanks Inc doesn't have a tank for my '71. Might need to go a specialty one made by some place like Ricks. But yes, I'd like it to be original looking as possible too.

I saw Stacy David installing a Holley Sniper system and I swore the combo fuel pump sender looked just like a b body sender.

You do not really need a specific conversion for your car, you can use 71 specific components (tank) and still do it. There are essentially 3 methods to accomplish the tank or fuel side of the conversion;

1. use your existing tank and an external pump. You will need to add a pre and post filter (same for any EFI system). The down side to this is that the pump does make some noise but for most that isn't a problem, also the pumps tend not to live as long as internal pumps due to heat (internal pump remains cool because it is surrounded by fuel). How long an external pump will live is kind of a relative term, meaning it will probably live a long time commensurate with how much you use the car. External pumps were used for a long time in production cars and would go 60 - 100K miles. You may have to run a return line and might have to figure out how to connect it to the tank depending on your tank's configuration. A 71 should have a vent line or perhaps an Evap line that could be used. You will have to vent the tank or the gas cap as well. An upside of this method is that the pump can be readily accessed if there is a problem or you want to go to a different/bigger pump due to making more HP.

2. use your existing tank (or a new replacement) but modify it buy installing an internal tank. There are kits out there for putting an internal pump into the tank which requires cutting a large hole into the tank and installing a pump. This method was done (and still is) for a long time before EFI specific tanks were being made. The pro to this method is a lack of noise and keeping the pump cool. The con is that if the pump goes out you will have to drop the tank (unless you install an access door in the trunk).

3. get a custom tank made that is EFI ready. There are several companies that will make you a tank to your specs. The down side it the cost, most are $450+, however the tanks are robust and very well made in most cases.

The fuel side is normally the hardest aspect of the conversion, but it isn't that difficult and the conversion is well worth the effort.

I appreciate you taking the time to write this up. I'm aware of all you stated. I was going to look into having one made, ore take mine of and send it to some one. My tank is "new" per say. I've only put like a gallon or two in it just to fire off my engine and no miles on the car. I'm leaning towards having a pump in the tank overall. Oh, the thought of throwing more $$$ towards my car...YAY!

Dennis-what did that tank run you if I may ask, roughly?

Dennis H · Jul 17, 2019

Lost the receipt iPad dumped my “Notes. Pretty sure it was about 1600. Remember, it was custom with increased capacity and the best PMW pump available. It was about the same cost as the Pro Flo 4 itself. 1000 miles now. Perfect. Quiet. Extended range on the road really helps.

Not bad prices, if you buy a Tanks Inc. (I know they don't make one for your car) that runs you $250, then the pump is another $250, then you need a sending unit which is like $30

Dennis H · Jul 17, 2019

If going efi, don’t try to save money here. Underhood pressure pumps may save $$$ but imagine being on the road in bumchuck trying to cool fuel or dropping a tank while fixing a pump. Get your wallet. Get cool fuel. Get a pump that is quiet and goes to rest when not in high demand.

Funny/ironic. I emailed Aeromotive about a month ago, simply because they're close, and they told me "no product available for my car and no plans in the future". :wtf:

. Guess I'll try again with them. Also, looking at their site, I don't see the picture you posted

rrTor-Red · Jul 18, 2019

^^^I see the tank now, sorry

1967coronet440 · Jul 18, 2019

Your best bet is going to be this aeromotive tank or like Dennis did with the custom tank.

rrTor-Red · Jul 18, 2019

67coronet-I'd rather stay with a factory appearing one and now looks like Aeromotive has one. Looks like I can pretty much get the majority there and then get a Sniper from Holley. Thanks for the info on Aeromotive. Like I said, their email wasn't promising as of 1-1 1/2 months ago

Dennis, so you would recommend the Ricks Tanks? about to jump on a good deal for an in tank pump stainless tank, but i'm going to use it for a mechanical fuel pump (until i'm ready to switch it over for the in pump fuel pump, pending some type of pump hat that i can plumb for the regular fuel pick up or use one of their in tank pump hat minus the fuel pump)

Holley makes some of these pumps, https://www.holley.com/products/fue...ters/fuel_pumps/in-tank_retrofit_fuel_module/
You just have to modify the tank.

thanks, received some info from Dennis. Also read up on venting issues with these tanks and then having to buy additional products to fix them. might just end up going with a stock tank and then when i'm ready to pull the trigger for EFI, i'll get me a retrofit pump kit. too bad, that Ricks tank would have been so pretty.
