Hi all,
I've been looking through these forums for awhile. Tons of good info around!
I've got a 94 short school bus with a 7.3 IDI non turbo, at about 280k miles. Its an E350 frame and so far every part I've ordered for an 94 E350 as worked out.
Recently my MPG's have dropped down to about 10-11 MPG! It used to be 14-15.
I did noticed the fuel return lines were leaking around Cyl #8. So I've replaced that. Haven't put much mileage on it since then, so I don't know if that's helped or not yet.
But anyways, I've been pondering ways to increase my fuel economy since I'll be putting some miles on this. Planning on doing an electric fan conversion. I'll try to take some pictures of that setup when its done.
The slightly major project I'm looking at is swapping out the rear axle for one with 3.55 gearing. Currently I'm at 4.10. This thing is 90% highway miles, and zero towing so I figured that could help.
I'm wondering if someone could point me in the right direction as to what axles are going to fit? Is something from an F series truck going to have the same mounting points as the E series van?
Thanks for any help!
