Vacuum Adjustable TBI Fuel Pressure Regulator

[EagleMark]

See I would go that route for my application since I already have the Dual TBI setup with an external regulator, only problem is the wimpy 1/8"NPT ports. I would have to machine it for -6AN, that's if there is even enough material to do so. Or buy the Mallory for $120.

I was just helping Dave out with his idea.

Dave, I was going to try to turn one out next week, but I am in the process of re-powering the lathe to try get rid of a vibration from the variable speed belt setup. So it may be a couple of weeks before I get parts. I might try to get part of it done this week at work if I have time.

Hav'nt seen much of you since you bought that lathe/mill... my kid ruined another 5 gallon bucket of used oil for your heater with water/antifreeze... again... stop by if you have time in town.

Mark, I will try to stop by next week with an empty bucket. I have been spending a lot of time on my newest toys, I will bring one by and let you check it out. I don't want to threadjack so I will just say...."Kalashnikov".

I believe this is what they look like.

Thanks for the pics. I've been using a Marine version fuel pressure regulator for my testing, which looks similar to the pictures posted above.

nice tbi. was that a purchased one or did you machine the ridges off. with a tiny bit of tweaking that vacuum nipple would work great as well.
