1967 Corvette fuel pump 40433 inlet fitting

[Timothy B.]

I am in search of a original fuel pump inlet fitting for the (1967) 40433 pump. If anyone has one in there goodies bin or has a source for one I appreciate the lead. This fitting threads into the inlet boss on the pump and is 90* to connect to the fuel hose from the line on the frame.

Thanks, Tim

Tim,

According to the 1967 AIM (UPC 8, sheet B3) the part number for the elbow is 538570. GM # 538570 is listed in Gr. 3.161 and Gr. 1.745 in my 1967 Chev. Parts Catalog and described as " 3/8 hose to 1/4-18 threaded pipe". Apparently this elbow was also on early and mid 1966 Corvettes (538570 replaced with 137423 on 3/21/66 as per drawing revision).

I dug thru all my original fittings, etc., and found a 1/4"-18 threads to 3/8" hose elbow as shown in the photo below. It came with an original 40083 fuel pump that I bought at a swap meet many years ago. I do not know if it is an original 538570 elbow but it fits the description. It has a "EEL CO" logo ("raised") in the shape of a triangle or pennant. The elbow appears to be steel but is not magnetic. It is not brass even though it appears to be brass in the photo. It is gray in color. It is not for sale (at least for now) as it is the only one that I have ever seen and I need to do more research . Maybe other members with original 1967's will have some input.

Maybe the Dorman 785-430 brass elbow is similar to GM # 538570 as shown in the link below:

BTW, GM # 538570 was also used 66-67 Chev. (283) models w/closed pos. vent. as per my 1966 & 1967 parts catalogs.
