Avanti, Avanti ll, Blake Must be in good condition and automatic Ideally in Pacific NW area if possible, as I am in Port Angeles, WA Thanks, Stuart 707 799-1927, stuartkiehl@me.com

Hi Jim, John Hull and another Avanti expert in Palm Springs, CA, said it is a Caprice chassis. Any thoughts on that?n Thanks for input! Stuart

It sounds like your car's serial number is either R4833 or R4834, which IIRC is in the range of the "round-headlight '64s." To me those are the most interesting Avantis of all. Is your interior solid color and mostly like a '64? --Dwight (R5255, R5272, R5407)

My car is all part, the engine is out for rebuild but I did find the fuel pump and the restrictor is on the fuel pump itself so I guess it's a '63,,,

Titled as a '64, round headlights, later production number, one of the last 809/810 produced, so it could be either one,,,

I've got a similar issue to deal with this Spring: Mine has already been sealed shut, but the glass is cracked. I have the new glass and depending on condition of the mechanism, may resurrect the functionality of the sunroof... or not. I'm not sure if the mechanism works anymore. If it doesn't, that complicates removing the old glass. So I, too, am interested in how to proceed.

I had the exact same problem on my 82 model. It was the antenna. I removed the nut, cleaned everything really good and then applied some black silicone gasket sealant to the area. After I tighted the nut down, I wiped off the excessive sealant until everything looked good. Be sure to check the antenna drain hose and be sure it's clear if yours has one. The water no longer is a problem in my trunk!

No hog troughs on a 1989. If its a Monte Carlo chassis you can use S10 drop spindles to lower the front end. I had an article in the Avanti Magazine on how to do that about 15 years ago. Good luck, Jim Wood

I called Myer's Studebaker Parts. They currently don't have any, but they make up another batch when they run out, so they'll be making more next week and sending one to me.

We live in difficult times…. Thank you for your concern.

Sorry if I'm disruptive.. My concerns are for us elderly members who will be visiting Motown. I grew up in that area.

Okay, okay boys we get the message…..ENOUGH!!

Stacy... We've discussed this before...but.. Wifey doesn't want to wear a flak vest? Ya know, growing up around areas like that, ya develop a "street sense" and avoid areas of trouble, The hair on Your neck stands up and ya move along. My prayer/desire is for those who didn't grown up like that will be safe since they are not ''street savvy''. These folks just blindly enter into bad situations. The best of my understanding this Hotel is in Livonia, which at one time was a fairly safe community. The Problem is the event has road tours into bad areas. I LOVED the Henry Ford Museum, in Dearborn, but that area at this time has gone heavily Muslim, and sorta in a corrupted way...(Hey, Y'all believe as Ya wish..just don't get violent with me).... I do understand there is a South Bend. Indiana Meet in May..That would be a consideration, since it is the birthplace of Studie.

I appreciate everyone's help. I'm definitely missing the return hose nipple with the .043 orifice. The one I installed is a standard nipple for a 1/4 inch inside diameter return hose. The inside diameter of the nipple is probably too large and allowing too much fuel to bypass back to the tank. I checked my shop and parts manuals. The 0308-8 group of parts is for the return line, and one nipple p/n 1558295 is listed, but there's no other description, and the parts are not illustrated. Is p/n 1558295 the correct nipple I'm looking for? I'll call around to see if I can find one. If not, I imagine I can make a brass plug to fit inside a standard nipple and drill a .043 hole through it.

If you’re not worried about keeping original a filter like this would work. Just run a 1/4” hose down to the return line. this is a NAPA 3054 filter

This is a picture from the work shop manual. The second picture is a screen grab from a posting on rebuilding an R series pump. I had time to dig thru some boxes today and found the restrictor fitting from R1358. The third and fourth picture show the restrictor fitting. A #57 (.043) drill bit just fits snuggly.

Excellent reply, as i too saw that it was going to be held in Detroit, where I was from and wondered who decided that? Not where I would have picked for that kind of gathering as there are many other nice suburbs in the area outside of metro Detroit that could and would have been acceptible. I asked my wife yesterday want to go? got that look, and a big NO!!!

My Avanti is an early 1963 model with the return line coming off the side of the fuel pump. R1204. The "T" fitting was still installed on the side of my pump. The port for the return line was plugged with a NPT pipe plug. I didn't remove the T from the pump since the line to the carburetor was still attached. One of my suspicions was that the return line needed a restriction somewhere to maintain adequate flow to the carburetor. I mentioned I installed a check valve in the return line. I suspect the rhythmic nature of the problem may be from the fuel pump developing enough pressure in the return line to overcome the cracking pressure of the check valve. My theory is: the engine runs fine while the check valve is closed, but once it opens, the fuel flow back to the tank is unrestricted and causes reduced flow to the carburetor and the rough running. Once the pressure in the return line drops off, the check valve closes and allows fuel to resume flowing to the carburetor until pressure builds up again, then the cycle repeats. Yes, it caused the car to buck between proper acceleration and poor acceleration as the cycle repeated itself. About one half to one second of running poor before switching back, then one half to one second of running well before switching back again. As long as I drove it easy, there was no problem.

Which year?

WOW!…..This is one VERY special Avanti!

Agreed!….Agreed!!

I visited his shop once. Dan has an amazing inventory of parts and is very knowledgeable (yeah, and opinionated). I’d love to attend his seminar at AOAI 24 get together, but not in the cards for this year.

Does anyone have a picture of this restrictor and return line to post?,,,

If it’s of any help, I was able to purchase the fitting from Jon Myer a few years ago, he may still have them. Mine is a 63 so the fitting was on the fuel pump return.
