Hey guys. I'm in need of a mechanical fuel pump on my 69 Jeep J2000. I cross referenced a part number to a Skylark and a different year J truck both with 5.7. The pump has a WAY longer arm on it than the old one. Will it work properly? Does anyone have another part number? This one is an Airtex 41197 with the long arm. Thanks for any help you can give.
