    Posted: 29-October-2021 at 1:12PM
I am trying to replace the fuel system on a 72 Gran Torino and I thought I saved the easiest part for last.  All I need to do now is to replace the mechanical fuel pump but I am having trouble getting a wrench on the upper fuel pump bolt.  Do I have to lift the air-conditioning compressor to get at it or is there a trick I cannot figure out?  Do I have to lift more than the air conditioning compressor?

Any tips greatly appreciated.

thanks,
Steve

I would bet the FP bolts are like getting at water thermostat housing bolts on 302's. I know I changed the fuel pump on my 351C-2V when I had it in high school, the AC compressor doesn't have to be moved.

Find the right socket and extensions for a ratchet. I love a 1/4" drive ratchet with extension and a 1/2" swivel socket, for the distributor hold down, and the 302 thermostat bolts. It likely will take that kind of tool combination to get at those FP bolts.

Thanks, Don!

I am able to get a crow's foot wrench on it and with a swivel extension, I think I will be able to get the job done.  I am going to make a trip to the store to see if I can just find a swivel socket to fit over the bolt and extend around the FP housing for a bit easier time of it.

Yes, some things require special tools or extra time for. I acquired my Snap-On 1/2" swivel socket over 302 years ago, then just for the distributor. It was about $15 off of the Snap-On truck, and worth it many times since then. I have most swivel sockets now, Craftsman sets I got many years back.

Keep at it and slowly figure out what tools are worth buying for a one time use, and others that are best to borrow or rent.

Funny, I didn't catch that in editing. I typed "30", and then wanted to say "over ...", so went back and changed the "0" to a "2", but obviously didn't delete the "0."

I bought that socket before 1988, when I was working at several dealers where the tool trucks visited every week.

I just replaced mine a couple of months ago, and I had to take the power steering pump loose to get to it without special tools. It was a breeze once I did that (the morning before our big car show no less!) 351C with AC

I replaced mine a week or two ago. I used a normal 1/2 inch wrench for the bottom bolt, and a socket with one of these wrenches for the top. I didn't have to move the power steering pump or anything, since the handle is short enough and can change its angle.

Thinking cause some engines that use this same pump have a spacer??

Removed the old one... bolts were finger tight & x2 gaskets fell off with it! lol... bonus 3rd gasket still on mounting pad took an hour to get off & clean up....ffs!

Figure i'll use 1 with some gasket sealer !

I think mine was cleaned and the new pump installed without a sealer. There is no pressure on the gasket, just oil from the timing chain. I am willing to bet it is there in the event you break one. Then you won't get stuck needing a ride to an auto parts store.

All done, top bolt was a pain but managed it from the top, without moving the power steering pump, just using a standard 1/2" spanner.... 1/10th of a turn at a time. lol & yes the 2nd gasket is for other engines with a spacer!

Should be 5/16. I used this on my Carter pump to run a 3/8 hose to my carb:

5/16" is the tubing size but threaded flare connections don't use NPT. it just is what it is for the 'tube nut' for the correct diameter tube for the outlet port on the pump. it's a straight thread so the NPT taper doesn't snug up before the flare crushes. if the fuel pump has a threaded inlet port w/o a flare then that will be tapered NPT unless it's a high-end pump, then all bets are off as it could be machined for a Straight Threaded O ring (STO) connection
