Anybody build a double pumper?

[Just a Six??]

The ATR unit used molded silicon pucks from the factory pulsator dampener. The coupler we have uses o-rings. Not the same.

That's what mine used & it looked like this fitting or quite similar but Blue. I wish I could remember the guy who had about 30 of them & I sold a bunch for him. At the time many people had old pulsators laying around & you needed 3 seals so 1 1/2 pulsators.
GM has them but about $25 each now if not out of stock but Racetronix version would be very, very similar. Some even added clips to hold the seals in place but I think it's overkill. I just had them here & used them.

I bet if you search KWIKR1 here & the other board you will find lots of pics.

Slip it on like the old ATR version.
Seals with o-rings as listed in ad.

The coupler will need to be annodized for E85 use? Or is it clear annodized already?

Ideally it should be hard-anodized for use with alcohols. These are not.

Do you think you'll have the batch annodized anytime soon? I'd pay extra for that.

Not anytime soon.

Hello. I'm new to this forum and I do not have a GN. However, I do have an 82 Monte Carlo with a LSX swap and a Procharger which will be fuel injected. I want to use a Racetronix or Reds DP but I'm leary on how the pickups feed line connect to the rest of the system because I don't want to mess around with 58 to 70 psi of line pressure. Before I take the plunge can someone tell me how you are hooking up your sender to feed the system. I have a Magnaflow 4303 but I would rather use a intank pump.

I don't mean to high-jack the thread.

At that power level I would think you would want a fuel cell? What power level are you shooting for, as that will detirmine what fuel system you should build. PM me for my number and I will try and help.
