mechanical fuel pump for FI 302 block

A quick back ground on what I am doing. A personal friend of 30 years was diagnosed with cancer. He just retired last october. His retirement project was a 52 F1 1/2 ton. With my wifes blessings I decided to finish the truck for him. the project is going well but I am at a snag. The engine is a 88 FI 302. Another friend has built the motor free of charge. It was converted to mechanical fuel pump. The fuel pump inlet and outlet are 5/16 and the new gas tank is 3/8 line. Will be running an Eldebrock 600 which has 3/8 inlet. This engine has a 2 piece eccentric on the cam. Does anyone know if this pump will run the engine if i reduce the line sizes to 5/16 or is there a pump that has 3/8 inlet and outlet for that will fit this block. Any help would be greatly appreciated.

You will have no problem dropping down to 5/16".. If this were a high performance engine I wouldn't do it, but for a driver, no trouble what so ever.

I wish your friend well, and you are a true friend to do this great thing for him. I have had friends like you in my life, and they are what really count in life.

Thanks ITOLDYOUSO, The engine is mild. Bored 30 over to clean up. Flat tops, mild hydrolic and Edelbrock performer intake. I see hyperformance fuel pumps on some sites but i don't think I need 110 gph. I have not been able to find a stock one that has the 3/8 fittings on both. I will try to neatly reduce the lines. I will keep looking but I am kind of on a time limit. Thanks Again.

If it's set up the same way as a '66 289/302 you could use a Carter from www.SummitRacing.com part# CRT6984 for $29.99 that would allow you to reduce the size with brass fittings.

I am being told that with the 2 piece on the eccentric that the older models will not work. I am not a Ford Guru so i am not sure. I don't know what the difference would be. Thanks for the reply.

Post a picture of the pump if you can. The only difference I can think of would be the length of the arm. Maybe Denny W will chime in, he's more of a Ford guru than I am. I going by what I know will work on early 389/302's and early 360/390's.

I have a '85 block w/mech. fuel pump. The pump is from an '83. I believe the timing chain cover was changed to accept the mech. pump. (I bought the motor done) My issue is, my power steering pump bracket now hits the fuel pump. I was going to use a later model serpentine set up. I didnt realize the pump would interfere. Keep that in mind, if you are planning to go serpentine

-- The fuel pump in question does run the engine nicely. Made test run around subdivision and it seems to do ok. My friend is still taking treatments and is having a hard time as you all might know if you have been with someone who is taking cancer treatments. With the help of son-in-law and 2 others the truck is on its way to paint shop( also another friend who volunteered to help).
This has been done in 32 days at approx. 10 to 12 hours a day.I will post a before and after pic as soon as i can if you guys are interrested. Thanks for your help and concern.
