Hi,
Very disappointed with both Holley and Summit brand FP gauges. I used two prior to the EFI install and they both failed. Then bought a new one from Holley for the EFI and never really trusted it. Then I installed the Autometer FP sender into the EFI/EBL setup. Good readout from 18-20 lbs. Started the coach this morning and the Holley gauge read 30 PSI. Connected the EBL to the laptop and it still read 18-20 so the Holley gauge has failed once again. I'm thinking the pulsing of the FP regulator on the TBI must be killing the gauge. The Autometer sender for the EBL comes with a little damper deal that screws onto the sender. According to their tech guy it stops the pulsing and smooths out the readout. Never liked the Holley gauge in the engine compartment anyway so out it comes.
My rant for the day
Thanks
