I put a Hy-grade kit in my 69 Camaro recently and it seems to work......for now. Just wondering if your reference on the accel pump was the material used for the umbrella ? If they're all junk then I will purchase several from you as I have several Q-Jet projects.
Thank you again. Brian

  Throw that accl pump in the trash and buy Cliff's. Best out there for today's gas.;)

Cliff Ruggles:
The blue color is meaningless, all of those pump seals will fail in this new fuel.  I see this ALL THE TIME, pic attached.  I put this information everyplace, but it often falls on deaf ears.  We test ALL of the pump seals currently available by soaking them in E-10 gas.  Most swell up quickly and stick in the pump bore, then end up tearing or rolling off the pump and getting would up on the spring under it.

For this reason we had seals made that will NOT fail in this new fuel.......Cliff
