The gear type fuel pump is bolted to the front of the cylinder block. The pump is driven from the forward end of the camshaft section 2 15 1 fuel pump removal. The fuel system used by detroit diesel is known as a low pressure fuel system owing to the fact that fuel delivered to the unit injectors averages 45 to 70 psi. I have a 1987 c 70 dump 97 000 miles with the 8 2 500 cid fuel pincher.

Detroit diesel had been building only 2 stroke cycle engines like the venerable 6 71 since general motors created the division in 1938 however by the late 1970 s with the raising cost of diesel fuel and the inefficiencies inherent in their 2 stroke cycle engines which caused them to consume more diesel fuel than their competitors modern 4 stroke cycle engines ddc realized that for them. Engines ship from stock within 24hrs we ship worldwide from our facility to your. Since the basic fuel system used on all detroit diesel engines is identical as far as components used the description of operation for one can be readily.
