Just use the high pressure pump off a for econoline or just about any early injected ford 4.9 or 5.8..most of those rigs came with two pumps,,a feed pump in the tank and a high pressue on the frame rail,,thats the one you want.. 89-95 around in there..They come with a isolater and mounting bracket with cool ribber mounde..suoer simple,,I get them for cheap..Benny if ya need one hit me up..I can get it for about half the cost here in tigard from ford....
