General Buick Tech / Fuel Filter

« on: January 22 2014, 03:09:50 PM »

Has anyone tested different brands of direct replacement in-line fuel filters for 86-87?  If so, when testing, noticed a pressure drop from one brand to another?  Cut the filter open to see who's got the most pleat surface area?  Fram G3727 available at WalMart for $11.95.  Original AC Delco GF652 about the same price @ $12.  Purolater or WIX option also.  Suggestions?

Thanks Steve / Scoobum.  Highway Stars has a pressure tested unit available at a good price if I needed to replace.  Have heard of people beating on the bottom of the tank to jar debris loose around pickup area (when in reality pump is going out probably) which then transfers the energy into the plastic baffle and cracks it.

Transmissions / Re: Tranny fluid

Thanks Steve, we're on the same page.  I am fine with mineral-based for right now.  Want to keep the trans alive for as long as possible while testing and tuning before shelling out for a major rebuild.  I do remember a lot of 2004R transmissions being rebuilt with Art Carr internals in Knoxville area when I lived there and them being filled with Type F after the rebuild.  I used to hang out with Mark Thomas (Puddin') if you know of him.  Built engines for Lawrence Conley in Texas for a number of years and then came back to Knoxville.  He had the fastest '85 in the country in the early '90's.  He really go me into these cars.

Transmissions / Tranny fluid

« on: July 08 2013, 09:48:10 AM »

I have a stock 2004R / stock converter.  Changing fluid & filter on car, has been in a museum for 6 years before I bought the car out of the collection.  Dexron 6 or Type F?  Any brand suggestions?  I run Red Line oil for engine / gear fluid.  I know that clutch packs are more finicky in transmissions with friction coefficients / fluids that are spec'ed to the clutches that the OEM manufacturer builds with GM like Borg-Warner, Moog, etc.  The Red Line oil is extremely durable, tends to be more 'slick' than standard synthetic oil manufacturers.  Type F of course has the faster / firmer shifts.  Obviously can't get Dexron II anymore.  Thanks for your input.

General Buick Tech / Gas tank replacement

« on: July 08 2013, 09:28:00 AM »

Changed fuel system components - injectors, fuel regulator, pump.  Racetronix 255lph complete unit to re-install in the tank.  How many of you have kept the factory gas tank with the plastic baffles?  Mine looks to not be cracked inside, outside ok just has undercoating sprayed all over it so it isn't pretty.  If it ain't broke, don't replace it?  I have the understanding that the plastic baffles can crack and then not be effective.  While the system is dry, I'd rather just replace it now if enough people recommend it and maybe (2) new stainless retaining straps?  Thoughts and comments appreciated.
