Weber DGEV Fuel Inlet

[Redfalken]

I have my Weber 32/36 DGEV mounted so the fuel bowl is facing the radiator and that makes the fuel inlet nipple pointing right at the valve cover (see photo). If I put a rubber hose on, bend it towards the front and hook it to a hard line that goes around valve cover, I'm afraid the bend might collapse when the engine bay gets hot.

Does anyone know if that brass nipple will just slip out and can I put something in it that makes a sharp right angle? Suggestions? If it slips out do I need some type of sealer for the new nipple?

Thanks!

I think you could cave it in with Vise-Grips, and draw out. Then tap NPT or (if possible) a parallel thread - less stress on the casting. Seal with Blue Hylomar when installing the threaded bit.

How about capping it off and replacing the big filter nut and making that the inlet. Anybody know a reason that wouldn't work? I wouldn't mind doing that on mine if it's doable.

Otherwise I'm with Adam, I'm pretty sure it's a press fit in there. I'd pull it and replace it with a threaded elbow - just be sure of which thread you want (pipe- machine- etc).

Kenny, do you have a pic of your throttle linkage? Looks like you were able to keep some of the original bellcrank stuff...?

I tried to figure out a way to use my mechanical linkage and the bellcrank but decided to go with a cable setup. Here's a shot of what I ended up using.

I don't even remember what I got it off but there were several later model sixes that had these brackets. It bolts on the block where the coil is, goes up over the valve cover and attaches where the carb bolts to the spacer. Works pretty good but I still need to do a few adjustments and figure out my cable kickdown to the C4.

I was thinking about using that as well but it seals by having a beveled edge (like a sparkplug) and I thought it would be a real challange to find some fitting like that.

I think pulling out the original nipple and tapping some threads would be easier. I suppose you might get lucky and find something that would just press in tightly and make a good seal. Maybe it would need some of that Blue Hylomar but it's only 5 lbs. of pressure.

I am pretty sure that the brass nipple just screws out.

I borrowed a unused 32/36 last Summer to use as a baseline against my old 32/36 to tune the engine and the one I borrowed did not have that brass nipple at all. Just a plastic plug.

I ended up unscrewing the one from my old carb and screwing it into the new carb. You just have to be careful that you don't damage it since it is brass. I would have to think that it is a standard thread...

 

[jamyers]

I've seen DGV's (and my DFV) that have threads in there for pipe-thread fittings, and also press-fit hosebarbs. Seems they come a variety of ways...some have the fitting coming out the other side even, and you could drill and tap the big brass plug if you really needed it in the center.

I'd put some pliers on the brass fitting, and try to unscrew/pull it, and see what's holding it in there. Not much danger of really messing it up, since you can always re-tap threads.

 

[cfmustang]

If it does unscrew, you can try Pierce Manifolds.

They have some different fittings that may work. They are also a excellent source for linkage pieces that I have not seen elsewhere.

Kenny-
Until you decide on the final setup you can bend a small length of 1/4" brass or aluminum tubing to form a gentle 90 degree turn and attach that to the nipple with a 1 inch section of fuel tubing and hose clamps, then attach the fuel line to the other end of the metal tubing. Or even better, bend a hard line from your filter (cool!) to the carb nipple with a 90 degree turn at the very end, and attach with 1 inch section of fuel line and clamps.
Good luck!
The engine looks great!

PS-
here is my latest modification to my Comet....

Very cool box Marc. I saw it on the Comet-List. Does that handle seem really secure? I suppose it depends how much weight you put in it. That's a really nice box man. Good work!

I wrote Pierce to see what they might have in the way of fuel inlets. Keep us informed if anyone tries removing the stock inlet. I might try it this weekend but it's my daily driver so I'll have to figure something out quick if that brass inlet gets trashed.

 

[Redfalken]

Does anyone know anything about banjo fittings? I just happened to see a photo of one and thought it might work where the brass plug in the middle is. I'm not sure how they seal but they seem to be used in fuel applications.

 

[Redfalken]

Does this seem like it would work? The description reads "Edelbrock #8089 Carburetor Banjo Fitting (with 3/8" inlet, 5/8"-20)". I checked out the brass plug that is in there now and it seems to be a 5/8"-20.

 

[addo]

Might work if you can get enough torque on it for the copper crush washers to seal. They're supposed to be replaced or re-annealed if you dismantle the coupling.

 

[jamyers]

If you get one, let me know how it works - The threads on my DFAV were worn to the point that a fitting would bottom out before the pipethreads sealed (sideways-mounted, pointing to the rear). Last night I installed a 1.5" pipe nipple with a coupler on the end just to get a seal, and also had to bend a longer piece of steel line to get to it since it's farther back now.

If I could plug it and use the center fitting, I'd do it in a heartbeat. Otherwise, I think I'll drill out the inlet passage on the other side.

 

[Redfalken]

One thing I just noticed yesterday on my exploded view was that there is supposed to be a strainer (part no. 10) that comes out when you remove the brass nut. Mine doesn't have one and I don't see them available from the normal Weber parts places. It seems like it would be nice to have one there so my plan is to try and find a strainer and a 90 degree nipple to replace the original one that is straight. Maybe this weekend I'll try gently turning it to see if I can get it out.

 

[jamyers]

Mine has a strainer, but it only catches big stuff - every time I've opened up the carb there's fine dust in the bowl. I guess it'll keep chunks that would clog a jet out, though...
