I would guess it's just the switching on and off rapidly.......some electric motors just can't take that.......so rather than being just on with a regulator to control pressure, they are controlling pressure by cycling the pump on and off rapidly
Yea. I saw pics of their tank for 71 Buick GS. They look nice. Anyone actually modify an original tank? I would love to see pics of how it can be done?
If you can get a new tank with EFI pump setup for a reasonable cost, I'd go that way. The alternative I've been recommending lately is the Holley mat. A surge tank can be done slightly cheaper, but the costs of the alternatives have come down a ton in the last ten years.
What do you guys recommend on the fuel line part should I just buy a kit with hoses and the AN fittings. Looks like tanks Inc has a tank and I'm going to get there in tank fuel pump as well . But there universal fuel line kit is 195 bucks.
Joe when I did my install I used a push-lock hose and fittings. I'm terrible at remembering all of the details, sorry!! I can't remember exactly, but I'm pretty sure the box said the hose was made by Eaton. The same guys who build big truck transmissions and such, as in Eaton/Fuller. It may have been marketed/sold by Aeroquip... I bought 2 boxes of the hose in -6AN which I believe is equivalent to 1/2", or whatever Aeromotive recommended for their Phantom Stealth In-Tank system. That gave me enough to plumb it from the tank to the filter, filter to regulator and then return from the regulator back to the tank. As for the fittings I went with Fragiola in black to match the hose. Again I followed Aeromotive's recommendations to use a 45* fitting from the tank instead of a 90*. I think I needed 3 of them: one for supply, one for return, and one for a vent. I needed two straight fittings for the filter inlet and outlet. Then three more for the regulator again for supply, return and vent. I think I used 45* for those also. I already had a pair of stainless steel braided lines to feed the carb from the regulator.
