Hi All,

Need some ideas for a new racing fuel pump for my car. Currently has a Holley Blue. It has lived a long and LOUD life for the last 7 years (with a couple of rebuilds).

Now it is starting to sound funny. The pitch of the motor changes, up and down constantly. Figure it's about to go.

Never had any fuel stavation problems with it. I designed to whole system to cut out restrictions and it has worked well. Braided -8AN stainless and aluminum fittings throughout, no 90 degree turns anywhere.

I want something that can supply my current 383W along with being ok for a future 500+ BBF.

There are alot of pumps out there. Experiences? Looking at a Barry Grant 280, but the fittings on it are -10AN. Would be a pain (and not much room in the pump location) to use adapters to adapt the -8 line to -10 pump. The adapters would mean an -10 fiting on each side of the pump, then an adapter before hooking up to the line. Stacking the adapters like that would make it like 9-10" long. No room unless I move the fuel filter, pump mount on the frame etc.

Thoughts,

Later,

David Cole

Dave,

You can use a fitting that is -10 on one side to screw into the pump and -8 on the other. My Superflow (now Magnaflow) pump/filter combo uses a -12 in and out of the pump/filter assembly. I use 2 -8 lines into a trick "Y" that goes -12 into the pump and I use a -12 to -10 fitting on the outlet side.

Going -10 to -8 is not a big deal at all....it's one fitting no larger (maybe very slightly larger) than the 3/8 pipe to -8 that's in your Holley pump now. I'm pretty sure that Barry Grant sells the fittings your after, radiused inlet....real nice....if not, I know Magnaflow does.

I'm not a big fan of Barry Grant stuff in general, although I have used his pumps and regulators without problems in the past. In fact, I have a BG regulator on my car right now....I like the Magnaflow stuff. I got a good deal on mine when it was Superflow and I've sent it in for a service/upgrade once in the last 10 years. Had I not gotten such a good deal on it, I would have probably gone with the BG 400....I also like the fact that the pump and filter are one unit, the whole mess is only about 8" long without any fittings on it.

BTW, my car was running out of fuel with a Holley blue pump with a 19# spring in it when the car ran an FE....it picked up a couple tenths and about 3 mph with a good fuel system.

Butch is right about the fittings. I run a Holley Volumax 250 on my car and I run alcohol and it works great. It has the same -10 fittings as the BG. Personally, I dont care for the BG stuff due to the fact most of their salesman are a real pain to try and deal with on the phone.
When it comes time for me to buy another pump, it will either be another Holley 250, or the bigger 350 Holley.
