aspeltz Posted September 27, 2012 Share Posted September 27, 2012 I just received my new rebuilt fuel pump for my 707A. I'm planning on using all new hardware and fittings into and out of the pump. I heard to not use teflon tape on fuel fittings. If so, is there anything else to use. I don't want any leaks.

fxfymn Posted September 28, 2012 Share Posted September 28, 2012 If you are planning on using rubber hoses make sure you get the newer high pressure hose made for fuel injected engines.. It will outlast the old stuff. Quote Money, sex, and fire; everybody thinks everyone else is getting more than they are!

609albert Posted September 28, 2012 Share Posted September 28, 2012 just for my future possible need ,where did you get a rebuilt fuel pump? Quote Link to comment https://www.bigmacktrucks.com/topic/27538-707-fuel-pump-fittings/#findComment-139520 Share on other sites More sharing options...
fxfymn Posted September 29, 2012 Share Posted September 29, 2012 The Ethanol in the fuel will also degrade the older hoses....found out the hard way too.Yep; I'm redoing a 72 IH 1310 right now and I'm going to run copper where a hose is used now. Too many sad stories of fuel hoses letting go that caused a fuel fed fire.After the show season is over I'm going to do the same to the 52.

41chevy Posted September 29, 2012 Share Posted September 29, 2012 I found that out on my 55 chevy. The E 10 we're forced to run destroyed all the rubber fuel lines, the seals in the Holly injectors and the bladder in my fuel cell. Learned this is SOP for the older systems. Now I'm a chemist for my older vehicles. Viton or equavalent fuel hoses and seals, lead additive for fuel (probably not needed except in my mind) and motor oil with a Zinc supplement to prevent cam wear.

aspeltz Posted October 1, 2012 Author Share Posted October 1, 2012 Albert,I used Arthur Gould Rebuilders in New Yorkhttp://arthurgouldrebuilders.com/Arthur Gould Rebuilders5R Main StreetKings Park, NY 11754United States(631)269-0093Over the phone he quoted me $80 for a single action and $100 for a dual action. They rebuild yourworn out pump you send to them. I had a single action and was charged $90. I paid shipping both ways. They use the viton or equivalent diaphragms. Turnaround time in their shop was about 3-4 days. Came back looking like brand new.Other people here have used Kanter Auto in Boonton NJ. I called them before Arthur Gould with part numbers for a quote and never heard back. Big turn off for me.

Gmerrill0516 Posted January 9, 2013 Share Posted January 9, 2013 I'm working to get a 49 707A gas engine in the LS85 running and had wrongly assumed that the lack of a mechanical fuel pump meant it didn't have one from the factory. WRONG. I have a 707C engine for parts that came with a pump installed. I know I can get it rebuilt. Does anybody know if it fits the A engine? Also, what the hell drives it? the cam and the third shaft are on the other side of the block? Any help would be appreciated. They appear to mount in the same location on either block.I know I could use an electric unit as long as I make sure I tie it to ignition power and probably a secondary fuel switch to make sure it can get shut off particularly in a fuel leak situation. I prefer the stock hardware whever I can run it reliably. If the 707C unit won't work, does anybody have the unit I would need?Thanks for any light you may be able to shed on the situation.Greg Quote Link to comment https://www.bigmacktrucks.com/topic/27538-707-fuel-pump-fittings/#findComment-155999 Share on other sites More sharing options...
