I do rebuild them by installing a good 1.7 diaphram in a 2.0 core. The calibration is done with a wavetek meter which I have the specs to do 037 and 043 MPS's. Resealing them is a pain as is taking them apart without destroying 'em.
Yes, the Brett ins ones work but it ain't the same as they set them up for only 1.7 MPS's. Mild differences in calibrations and if they install new steel cells the thing runs like shit with very poor drivability. Throttle response just plain sucks! You can send me you two MPS's and I'll work on them. here is a pic of the inside of one Attached image(s) |

Brett Instruments no longer exists...It was sold to Fuel Injection Corporation. Their price, supposedly across the net, is $275 for a rebuilt one.
I am having some rebuilt (maybe, a long story) that could be sold for $200. It is a waiting game on this one. The one that Scott Kline has was rebuilt by the old Brett Instruments (I can tell by the tag). If all the diaphrams are the same, I have a shit pile of MPSs (various numbers)....Maybe I should take them apart and retrieve the diaphrams (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) |

Yes, that is the only thing in them that is worth $$$. I have MB guys emailing me to rebuild theirs.
Do a test sometime running a nos unit and then plug in a Brett rebuilt and then a AA one. You will be suprised at the difference in throttle response! |

I have a few extra MPS' that I am holding onto 'cause I have 2 cars with d-jet.
How about the compatibility of an MPS from my type III and my 1.7 type IV. They look the same to me, although I haven't looked at the number. |

Not knowing all the intracies, I would assume the diaphrams were essentially the same from a lot of cars that had DJet. The numbers would refer to calibration and electrical outputs.

the type 4 have the altitude adjustments built in which is way better than the type 3 style. |

turns out i had a un-molested T-3 MPS in there....from a 1600 engine. So my T-4 MPS should be closer to spec.....its a 1.7 MPS......still has the miss....i think i should check continunity between my crimp connections i did with the Fi trigger point connections. How hard is it to take out my FI harness wiring to look at it? Oh and are the 1.7 and 2.0 harnesses interchangeable..? I have 2 1.7s that i could fix while the 2.0 is doing it's thing.......i believe my problem IS electrical (due to the intermittent random problem)and i believe that a harness may help with my issues....

Easy. Take pliers, and pull the ends off, then cut any wires that get in the way, when you pull hard.. and do pull *very* hard. M |

Sent ya a PM on a source for a known good MPS... I have one that I'm not sure of. I'll send it to you for free if you would like... As far as the pulling of the FI harness, contact Bowlsby, he's got the shizzle fer ya....

If you take each harness connection off, after you have properly tagged it, and just keep marking, and removing til it comes out.. I am pretty sure taking pictures of it as you go will help alot.

Hmmm... I have a spare sitting on the shelf as well. Martin Baker tells me it is good based on his doing some quick test that I did not see. But considering it is Martin Baker I am going to trust that he knows what he is talking about. What are these things worth??? Mine is from a 2.0 with 70K miles...

Pull a 15hg vacuum on it for 5 minutes as it should leak down hardly at all. If it drops quickly its toast.
a good 2.0L MPS is worth $150 to 250 if its been checked for vacuum and calibration. Lots of buggered MPS's out there that run like shit, thats why they are on the shelf. |
