I've found the following submerged pump tanks: '67 Chevelle tanks (fit? or fit with filler neck xplant?), Rockvalley '67 buick (pricey), '65 buick skylark (fit?, filler neck xplant required?), Silver has a nifty recirc reservoir, and then there's the 90's B-body requiring trunk surgery. I'd appreciate opinions and lessons learned.
You have cited mine, and I'll just simply repeat I'm very happy with the setup in two cars and a combined 60,000+ mile of drive time.
I'd prefer an in-tank pump for noise and longevity reasons. I'm also intrigued with returnless variable pressure systems.
if you have loot to spend cant beat the fulley optioned rickstank/vaporworks tank with intankgen5 camaro pump cheap tank optiuonsfor intank pumps would be gn tank or b-body tank(petty wide though and cutting involved) best option fort he money would be spectra carb tank with fuelab prodigy pump(inline) and fuelab electronic fuelpressure regulator(can control two pumps) with this setup you dont need another 300 adon tocontrol the pumps to last on the street, and its very quiet for inline
Have you checked Specra Premium? (Re: Fuel injection gas tank for '67) Dear Boe and V-8 Buick leading edgers, Have you looked at Spectra Premium Industries? They have an EFI equipped tank for my trusty 65 Buick Special wagon (cleverly disguised as an El Camino tank.) I just went on their website, but couldn't make sense of the options for a 67 Buick. Still, it is worth a look. They seem reasonably well designed now and are much less expensive than a custom tank. Cheers, Edouard :beer
The '67 Chevelle and '65 GS FI tanks mentioned in the original post are made by Spectrum. Question is: do they fit as is, or require different filler necks?
Trot onto the internet and look for a manual called "Jags That Run". You will find a neat little idea that saved me a lot of cash. In it, he describes an external reservoir that only cost a few bucks to build and implement. It utilizes the stock tank, a low pressure electric pump mounted externally that feeds the little reservoir. From that, a high pressure pump supplies the needs of the FI engine. I used his method on my LT1 powered 67 Skylark. It works great! Of course there's a return required. My tank already had that and the line too. He discusses all the ins and outs of retrofitting a fuel injected engine. Goof luck!
Yea/ your talking about a fuel surge tank.. you can bu6 these for 100 and up if you can't or don't want to build one..one of these with I stock replacement carb tank is. Better then an efi tank from spectra.
Another option to consider is modifying your gas tank. Tanks Inc makes an in-tank fuel pump adapter kit that is pretty interesting. I am pursuing this route with the MSD system and chose to use the in-tank pump with the returnless setup. I haven't installed it yet so I don't have any first hand feedback. http://www.tanksinc.com/index.cfm?ptype=product&product_id=84&category_id=61&home_id=61&mode=prod&prd84.htm
The tanks inc mod looks interesting. I'll have to measure another tank that I have. To rephrase the original question: Can anyone explain the difference between a 64/65 and 66/67 tank. Longer fill neck? different angle? Would a 64/65 tank work in a 67?
a cheap efi tank would be one from a grand national..all you need would be the gn straps and a rad hose to connect your filler neck to tank since gn neck is offset..or just do some cutting and rewelding to center neck
The 64-67 tanks are a tough go because they are very shallow with the stock sender hole in the front instead of the top. I don't think the tanks kit will work as I considered it for my 64 and decided it wouldn't work because the tank is so shallow I think. Sorry I can't say if the 65 is the same as the 67, but I will bet the tank maker can. There are worse options than changing the filler neck (like any of them described above IMHO). Returnless would be a tough go without an ECU to control the fuel pump speed; probably fine for a mild combo but many people in the Mustang world making 500 hp+ ditch them for return style due to problems. vRecent revelations are that the ECU speed of the <95 cars can;t keep up with the necessary dynamics of a highly modified car.
I emailed Spectrum who simply replied that they do not make a tank for my application. Does anyone have knowledge of 64/65/66/67 original tank similarities and differences?
Spectra GM37GFI is the one you need. Its for a 67 442 comes with the filler neck and correct dual vents.
Bought on amazon for <$400. The filler neck is definately different: approx 1.5" shorter but the angle should be good. The tank itself looks like a great match. Has the FI baffle inside the tank. Should make for a nice winter project.
