  1. Original Scarab

    Saw a couple of these at Amelia Island about 5 years ago, interesting cars!
  2. Looking for 240z Scarab

    Good luck. I have a friend that just found one that will probably take $20-$25k to get presentable, another $10k to get it concours ready. I haven't seen one for sale in the last 10 years except fully restored for $60k+
  3. Is my 1973 240z an origional scarab?

    Original Scarabs will have an additional VIN plate stating it was built by Scarab and a vehicle number. There will also be a dash plaque on the right side stating in script "Custom Built by Scarab". And then there's the qtr panel emblems of the scarab bug in gold, Scarab on the fenders, some came with Scarab valve covers, some with Scarab in the seat backs. Also "SCARAB" cast into the bellhousing. All of these items EXCEPT the badging could be purchased from Scarab in a kit or piecemeal.
  4. Holley fuel pumps are bad?

    I ran a Holley with a regulator for a long time but got sick and tired of the noise! I switched to the Airtex E8016S and couldn't be happier. Have to listen close to even know that it's running. $28. I've got 3xDCOE40 Webers, it has no problem keeping them full at 3psi.
  5. 240Z Tank Modification

    Yep, took it for a test drive down to the gas station to fill it up and check for leaks. All's good! The pump is SOOO much quieter than the external!

  7. 240Z Tank Modification

    I just finished modifying my tank to accept an Airtex 99-02 F-body fuel pump module. Started with using my shop-vac to blow all the vapors out Then cut a hole in the top and welded on the VetteWorks retaining ring. Then did a test fit of the module in the tank and set the tank in place to locate where to cut the hole in the hatch floor. A friend donated a storage bin lid that I refinished to cover the hole. But I needed to build a base to accommodate the increased height of the tank + module + plumbing + wiring. Some 3/4" plywood, pieces of Home Depot paint stir stick and piece of aluminum angle did the trick. I think it turned out pretty good!
  8. EFI conversion

    I looked on Rick's Tanks website, didn't see anything for S30s. Is that tank intended for some other vehicle?
  9. EFI conversion

    Wow! That's a great looking tank. I just modified my stock tank, installing a Airtex 99-02 F-body fuel module. Cost me about $400: module, retaining ring, AN fittings.
  10. Lets see your V8 in your Z.

    Changed from the Carb'd-draw-thru-turbo that was originally a Scarab Stage III engine to a Blow-thru-EFI'd-turbo with Alky Injection. Much more drivable. Could never get the Scarab setup to run right.
  11. Speedo question

    Yes, it should work, Powerglide and Muncie 4 speed speedo outputs are the same with gears ranging from 17 to 25 teeth.
  12. 240Z Tank Modification

    You're tackling floor pans and frame rails? Wow, you're adventurous! At some point I need to do the same, PO or inexperienced shop jacked the car up on the "frame rails" and bent them and the floor pans. But that's down the road sometime. Are you adding the Bad Dog reinforcing to the frame rails?
  13. 240Z Tank Modification

    Jay, the adapter ring is stainless and the tank is mild steel. What did you weld with, TIG or MIG or...?
  14. 240Z Tank Modification

    I found some pics of these units and there is a sock inside and outside. I found one post where the guy had to lengthen the unit to reach the bottom of the tank to access ALL the fuel. These are meant to sit hard on the bottom, hence the springloading. He took two boneyard units and cut the 3 legs out of one and extended the other with them using pipe unions. Looked pretty good. Are you using the internal fuel regulator or external on your fuel rail? To use the internal I see guys simply making a loop from inlet to outlet and adding a T to go to the front of the car. No need for a full return line that way, no fuel heating from the engine. Wish I could but I need to boost reference my regulator

    Jay, Thanks for the link to the fittings! You say in your post that the pump sits about 1/2" from the bottom of the tank but with the sock it should be perfect. Isn't the sock inside the bucket? Is there also a sock outside the bucket? Also, are you going to run the stock pump or do the Racetronix upgrade. It's pump FPA-001B at racetronix.biz
