ih guys .. my dad had a 49 buick. black it was a good looking car and latter he got a 55 hard top ..white with rad intierior.. i am looking for the inline fuel preshure regulator ,that came up on this site .when i punched in miles master ,.. the pompany is in exeland wisc. but i cant get it to come up through the yellow pages . if you could help ..that would be great..thanks rick.. I do a fuel econemey thing that gives me 45 to 50 mpg. even on v8s ... i have some trubble with to much fuel presure this miles master is deiafram over needle ...the deiafram acks like a floot and operates the needle.. thanks for your help
Hi Rick, welcome aboard. I'm sorry I can't help with your car but I think there are a lot of others here who can. Are you working on the '49 or '55? Devon
Welcome! I'm not familiar with the "miles master fuel pressure regulator". It sounds very interesting. The best mileage I can get out my 55 is, 22 mpg on an open Interstate.
Re: http://www.v8buick.com/showthread.php?t=78484 I found this post, from five years ago, with the same question; http://www.v8buick.com/showthread.php?t=78484 Looks like, he never got an answer. When I Google; "miles master fuel pressure regulator", It appears to be an application for Diesel engines.
Back in those days there were several fuel pressure regulators out there....most of them just put a restriction in the fuel line.... the best ones would cut the fuel pressure down to 2 or 3 psi... and had a elongated configuration with a glass bowl and lever arrangement that controlled the pressure.... they worked best when mounted at the carb inlet fitting, because when you mount it further back toward the tank it causes vapor lock.... I havent seen one for sale in the parts stores for years.... dont know if they still make them....they only work on carbureated cars so the market is shrinking.... Seems like I remember holley making one....and the brand name Victor seems to stick out.....
I believe purolator makes an inline low pressure regulator with a dial to adjust, for carburetors. 0-5psi adjustment in 1/2 psi increments. I used one on my quadrajet and turned it down and down and down until it bogged under acceleration (ran out of fuel) then turned it back up 1 psi to arrive at the lowest pressure useable without leaning the engine out. It helps with float bowl flooding to reduce pressure on the needle and seat to a minimum. They run 20 bucks or less and will work for your application but wont look period correct. Ive seen the type you mention (from that period in auto history) run across EBAY every month or so. Many brands were used back then but of course the seals and components will be old and may leak when subjected to use today. Pay up to 50 for a original style regulator from the 50s if NIB. What tricks are you doing for your mileage gains? Any particular carburetor or is it stock? Ive messed around on my 350 buick and gotten up to 26 on open road without many stop signs or red lights, and little grades. This was using a carburetor enhancer modification to apply controlled vacuum to the carburetor float bowl, thus allowing for fuel flow adjustments with the turn of a knob (counteracting venturi vacuum). I also had water injection, more timing, electric fan, and ran the engine at 230 degrees with evans coolant. I have since replaced the engine with another SP code with ported heads and now the mileage suffers from low port velocity. I wish I had left the intake runners untouched and just worked the bowls. I may take the intake off and fill the floor with epoxy and install screens/mesh in the ports to reduce volume and improve vaporization of fuel that falls out of suspension when the airflow slows. The screens will increase the surface area and sheer turbulence and should help with vaporization.
What would it do if you just sandblasted the intake runners with real coarse sand to give it a rough texture??????
:Comp:Ah, yes. When I included Gasoline and Carburetor in my Google search; http://www.malloryperformance.com/pdf/FuelRegulatorsLowPressureCarb.pdf
