I don't have a Carter fuel pump , I have a Holley Red and it will fit between the carb and the Dist. I am not going to use the mounting bracket that came with the pump, I am going to make my own that will bolt to the two rear carb mounting bolts and to the botton of the fuel pump . I will have spacers between the bracket and the bottom of the fuel pump to raise ithe pump as high as I can to keep it as cool as possible. I think the Carter is much larger than the Holley so I'm not sure if it will fit between the Carb and the dist. and with the top mounting bracket it may be difficult to mount.
Hmmm....now that you say it....you are right - I will have to fabricate a new bracket, too - but even then it will be hard to mount. But I've heard that the Holley pump need the use of a pressure regulator. That was the reason my decision felt to the 5psi Carter pump. Hope I didn't made a mistake. What are the dimensions (diameter, height) of the Holley pump you use, Jack? The Carter pump is 5.5" high, but I can reduce her about 3/4" if I take flat head allens instead of the long mounting studs who come with it.
I also want to change all fuel lines to stainless braided Aeroquip hoses with Aeroquip connectors. I ordered a Quadrajet adapter fitting (1" to 6AN male), a 90 degree coupler (6AN female to 6AN female), and a fuel gauge adapter (6AN male/6AN male with 1/8" tread for fuel gauge). Now - not really "now", because I just ordered the parts, and they will need at least 3 weeks over the pond- now my carb's fuel "entrance" has a pressure gauge and shows in drivers direction. I'll have to choose either the left way around the carb, or the right way around the carb- back to the pump. On the right side is very much room while the left side would provide a much cleaner look, but there is the throttle linkage, and therefore very few room....decisions, decisions...
The very best way would be a tube instead of a hose from the front of the carb to the pump (rear of the carb). A tube would take less room. But how can I make these 37 degree seats at the end(s) of the tube? Is there a tool available to make these AN tube ends? If so- someone have a part # for me?
Also - how do I seal NPT adapters for fuel lines (reserve tank, fuel pump, fuel tank crossover hose) best? I use to seal oil line treads with teflon tape, but teflon tape particles are like poison for any carb. In the past I used it (very carefully) for fuel lines, too- but there must be something better available.
Our whole fuel system has 3/8" diameter connections - the carb, the stock pump, the main and reserve tank- except the fuel selector valve. This valve has 5/16" fuel line connections. The first time my bike had a 5/16" fuel line from the petcock to the FSV. Fits perfectly on the valve, but it was a pain in the ass to get the hose on/off the petcock. Most of the time it ended with bloody fingers, an angry Loaf, and an inch shorter hose, cause it was destroyed, and I had to cut it off.
Then I took a 3/8" hose - fits perfectly at the petcock, but brought me a leaking connection at the selector valve from time to time, cause it's too big...grrrrrrrrrr!!!! :? Is this damn valve somewhere available with 3/8" hose barb connections? Or better - an all-brass, fuel resistant valve with 1/4 NPT treads for AN adapters? Sorry...I was dreaming.
Oh, and the petcock....don't know who it was, but someone posted about 2 years ago better not to use 5/16" hose for the fuel system. 3/8" would be better for flow reasons. I measured the petcock opening yesterday. We can use 5/16", and don't worry about flow - because the barb of the petcock sure is for a 3/8" fuel hose....but it has monster sized walls. The inner diameter is as large as 1/4"....heheheh...so a 5/16 hose shouldn't hurt- it's an improvement! Hehehe.... :lol:
I know a lot of you guys have AN hoses/connections at your fuel systems. I would be glad about some pictures. Especially the area around the carb.
Post them, or email them to me, please - [email protected]
I appreciate every good suggestion.
