@robert-c-kelly Robert, If you have, or can get your hands on, an old take-a-part style pump, I suggest you buy a diaphragm from one of the vendors and rebuild an original pump. You can also contact Bob Marx at Marxparts in Wisconsin. I think he can help you with a properly rebuilt original style pump.

@robert-c-kelly i have been using this pump. works great. although you do need to get longer bolts. ive used on 216's & 235's Precision Fuel Pump M16094 | O'Reilly Auto Parts

I don't know about the sound but you need to really push hard to activate the diaphragm.

Using that pump on earlier cars requires modifying your fuel lines. The correct pump has the inlet/outlet directly across while that one has them offset to accommodate the changed motor mount locations on later models.

@tiny i havent had to modify the fuel lines on any of my early 216's or my 207. I only have to get longer bolts since the housing where it mounts to block is a lil thicker.

It's possible that someone modified them in the past. 37-51 (I have no personal knowledge pre 37) used a pump with the inlet/outlet ports straight across. After 51 the ports were angled like the one you posted to miss the motor mount. It's a not huge modification (mainly bending lines and removing a clip) but it's not stock for those wanting to maintain originality. If you're not concerned with judging points it's likely to never be an issue. There have been concerns with those new pumps being junk out of the box. If it were me, I'd contact Marx Parts and have them rebuild my original. Top notch job with alcohol resistant parts.

@tiny yes, thats possible. Ive heard great things about these and a lifetime warranty. We havent had one fail yet in dozens of cars. The one i had problems with was the stock looking non glass bowl pump. Is there a big need for original pumps? i may have a few extra.

They may be interested in buying them as cores. Original sediment bowl pumps are fewer and fewer as years pass. Might be worth a phone call.

@tiny Yes, i have a bunch just gotta find them in storage.

@captain1562-2  216 and 207 pumps are not he same. The mounting surface is different shape. I have seen the late pump on 1935 and 1936 engines, so I assume they will work but hey are not the correct pump.
