In our recent MFI high speed bypass article, a photo is included showing a high speed bypass from an Outlaw Sprint Car running at the Placerville Raceway, Placerville, Ca:
Brad Cauzillo, Marketing Manager, Kinsler Fuel Injection, added the following info to that photo: "...how NOT to plumb your race car.
The bypass valves should:
- a) Be plumbed as close to the pressure change source(barrel valve) as possible
- b) Never rely on a aluminum union fitting as a mounting source.
- c) Be connected with a length of hose on the inlet and outlet to provide anti-vibration for the internal components."
