looks like I need a new fuel pump for my '67 442 4 speed. Coming from Chevy background I am not sure if a 400 c.i. is considered a big or small block in Olds terms but I need a mechanical fuel pump and having hard time locating one. Seems like all vendors so far only want to switch to electrical or it seems like '67 is different from other years. anyway, where is best place to buy one NEW preferably Delco but cant be choosy if they don't exist or can you get rebuild kit and if so do you have good luck with rebuilds? Any thoughts will be appreciated as usual. Thanks, Mike

 

Your 67 400 engine is a big block and mechanical fuel pump may be available at NAPA...
Here is one listed from NAPA: https://www.napaonline.com/en/p/DFPMF0152

 

thanks for fast reply and the info. Looks like the one

 

forgot about NAPA and they do offer one but I see that the tube from pump to carb points differently from pump. it shows tube coming out parallel to the ground and then up to carb. Whereas the one on my car points upward approx. at 45 degree angle then to carb. That being said I don't know if the one on the car is right or wrong. Does anyone have a pic showing original . Don't get me wrong I don't have a concurs car here but it is mostly numbers correct so if I can find the correct one I would like to . Any help is appreciated, thanks Mike

 

I have found pumps with same configuration as the one now on my car. Brands Delphi, Carter, and Airtex all look the same. But when asked about the 400 c.i. engine fitment they all say it doesn't fit but yet they say it fits all engines from 230-455's. Is there something special about the 400 that I need to know???????

 

All Olds fuel pumps mount the same and are therefore interchangeable. The differences are as you found in the angle of the ports, the number of ports (2 for non-return systems, 3 for return systems), and on some the GPH flow rate.

 

thank you, that is what I needed to know. I am still learning about Olds. But getting there thanks to all of you at Classic Oldsmobile.

 

A M4516 Carter is perfect for your application. It's one of their Muscle Car series pumps.

 

Thanks but looking at it the line to carb comes out at 90 degrees instead of the 45 that car is plumbed for already. Carter M6109 appears to be same configuration as what is on the car already. Unless there is a major difference in construction and/or fuel delivery performance that you or anywone are aware of I will stay with same plumbing. Just one thing less to mess with. But thanks for heading me in the right direction.

 

You said you had a 67 442. That M4516 is the correct unit for your car. You didn't say the line had been modified. Just tryin to help.

 

Hey 66-3x2 442 thanks for the help. I did not know it had been modified. the line looked like a perfect fit NOT hand made like I have done in the past so to me it looked original to the car . so going with your correct numbered carb for the car I will also get correct line. Thanks again, Mike

 

No problem. That's what I would do,get the pump and the correct line for originality. You will need a 90* fitting @ the pump to make it work. Good Luck.

 

Been out of town til now. Got the M4516 and ordered the "correct line" but the line fits the carb but not the pump. Which begs the question why would Olds require an extra fitting at that point? Just one more thing that could leak, right? Plus the "Bean Counters' would not pay for that fitting I don't think. So Unless the fitting is correct for a numbers matching car (mine's not perfect) I will stay with the M6109 and eliminate a possible leak situation. Any ideas along this matter will be appreciated. Of course I am assuming that I got the correct line???? I am working on that to make sure.

The pump has pipe threads and the line has flared fitting nuts. It uses a pipe to flare fitting.

 

Makes sense and that explains why I am not a plumber. thanks again

 

Well like I said in the beginning I have Chevy background and mentality and trying to install the Olds fuel pump I see (or rather feel) that there is no push rod to lift up out of the way and pack with grease before installing this pump? Am I correct in the assumption that you just maneuver the pump and lever in such a way that it just slides into place and bolts up without a whole lot of hassle or a whole lot of pressure? I looked up fuel pump in service manual and there are no directions only a note that it is operated by a concentric lobe. Thanks again, Mike

 

Yes, just insert it and it should align correctly. The flange probably won't sit flush to the block, but as you tighten the bolt and nut it will compress the pump arm and snug up to the block. As you said, this is not a Chevy so remember to put the pump in with the housing in the right orientation.

 

thank you, I feel better about the install. and thanks for the internal pic of the pump arm and where it sits. Too many years of chevys. That pic explains it very well. thanks, Mike

 

Final note with part #'s that might help someone else. For the original look I ended up with Carter pump # M 4516 from Summit, the original line to carb from pump # occ6603 was from inlinetube.com, and fitting was Edelmann inverted flare from Oreilly,s # 122640. Thanks to all, Mike
