Fuel Injection Fuel Meter Housing ID help needed

[Dave S.]

Needing to identify the application of a Fuel meter Housing #7014886.

It has a square Spill Valve Cover #7014895

Seems to fit into the 57 numbering system but cannot find it anywhere.

The 57 JG does not list it.

Any help is appreciated.

I don't recognize the number but that doesn't mean anything.

The only fuel meters I've seen which take the square spill valve covers are the sand cast type used mainly in '57. Is that what you have?

There should be some numbers stamped in the casting on the outboard side, usually low and toward the rear. What are they?

Re: Fuel Injection Fuel Meter Housing ID help needed

It might be those are casting numbers and after machining a different part number was assigned.

These 2 pages may help identify...

Jim,
Doesn't look like a sand cast piece.
After closer inspection there is a faintly stamped 902 up high directly above the high pressure pump hole.
Would that be a 58-52 style.???
Thanks for the guidance.

Rich,
Thanks for the reference. I had looked at parts books to see what I could find. Nothing.....
The 7014886 number must have been a Rochester products cast number and they stamped the 902 into it.
As I replied to Jim I finally did find a faintly stamped 902 above the fuel pump hole. I suspect that will mean something to the FI garus.
I'm thinking it's a 58-62 piece.

Re: Fuel Injection Fuel Meter Housing ID help needed

Dave, I just found this. see pdf attached. Maybe a '59?

PS and this page has info to support that too....

"Air and Fuel Meter IDAir meters and fuel meters were normally stamped with the last three digits of the unit number. Earlier units through the 1959 model year may have had all seven digits stamped on a part. For example, a 1958-59 #7014900 would have a 901 stamped on the air meter, and a 902 stamped on the fuel meter.
The 1959 #7017200 fuel injection unit number has an air meter stamp of #7017201 with a fuel meter stamped 202. Most 1962 and all 1963-65 air and fuel meters were no longer stamped as described above. Some early 1962 fuel meters may have a 252 stamp. On 1965 units, the air and fuel meters were not stamped with a portion of the unit number, as earlier units had been. Some units have the first four digits of part number omitted."

Rich,
Very interesting info. Thanks.
The chart indicates that the 1959 4900R came with the 902 fuel bowl. This unit was built as a richer unit according to the chart.
Interesting that this bowl came with an 001 high pressure pump which as I understand it was for a 1957 application. On the 001 pump it has 3 weep holes and on the pump was a paper tag that says it has 50% more volume. Was the 902 fuel meter in 1959 supposed to come with an 001 high pressure pump.???Funny how one question leads to another.

Dave, I'm unsure. Jim or JD will likely have that answer. Jim's buried in snow so hopefully he's still online.

Re: Fuel Injection Fuel Meter Housing ID help needed

Dave, To repeat what I just emailed you. The info in in the '59'-'60 judging manual. I edited the fuel injection section many many times for Dave Heitzman and Tim Mickey. The fuel injection section is the most difficult one for most to absorb.. So many fuel injections between the three years and variations of such.
As I suspected you fuel meter bowl is stamped above the back side of the fuel meter bowl Right above the hi-pressure pump. It's stamped 902.
Now the assembly line worker was supposed to stamp it on the side between the two upright "ribs". The 902 would then be facing the valve cover.
Over the years a hand ful of my '58-'59 fuel injection have been dinged because our judges saw the side of the bowl was blank. No stampings.
You wrote a little while ago and said you bowl was stamped above the pump.
Is it typical? Nope. But it is correct as someone at RP did that.
Thanks for your intense effort on finding out what your fuel bowl was/is. I would expect no less from you though.

John,
Thanks for taking the time to identify this fuel bowl and also assisting with the identification of my high pressure pumps.
Your efforts are appreciated by all.

Re: Fuel Injection Fuel Meter Housing ID help needed

The chart indicates that the 1959 4900R came with the 902 fuel bowl. This unit was built as a richer unit according to the chart.

The 902 bowl was used on both the 4900R and 4900 units.

On the 001 pump it has 3 weep holes and on the pump was a paper tag that says it has 50% more volume.

Whoa! You need to post a picture of that pump! All production pumps have gears approximately .480" wide, as evidenced by the thickness of the center section. The only way a pump could flow 50% more per unit time would be if the gears were wider and in particular if they are approximately .750" wide. I've seen only one pump with the gigantic gears like I just described. Please post a picture!

And while you are at it, how about also posting a picture of the fuel meter and of the spill valve cover. A 902 fuel meter should be a die casting but I've never seen a die cast fuel meter with a four-hole spill valve cover. I'd like to see what you really have there.

Jim,
Attached are photos of the fuel bowl. As you can see it has a 3 hole spill valve cover. Not sure where the 4 hole came from.

As it relates to the 001 pump I'll have to take it apart to inspect. I'll have to do that after New Years as I'm headed out of town for a few days.

Jim,

Attached are a few photos of the 001 pump.
The gears are in fact .73" wide.

OOooooK! Except for the location of the "902" stamp, that's a perfectly normal 902 fuel bowl.

Maybe I imagined that you said the spill valve cover was the 4 hole variety. I do have an active imagination.

No need to disassemble the pump to estimate the gear width. Just look at the width of the center section, between the end plate and the pump body. It's width will be within .001" of the widths of the gears.
